How to solve the dilemma of the hottest energy iso

How to solve the dilemma of "isolated island" of energy in Xinjiang recently, the national counterpart support for Xinjiang has been fully launched, and Xinjiang's energy industry has ushered in unprecedented development opportunities. The four-wheel drive development strategy of coal, electricity, oil and gas has initially taken shape, and the rich resources distributed in the North and south of Tianshan Mountain are making Xinjiang full of vitality. Although Xinjiang is rich in energy reserves, it is still an energy island with a serious shortage of energy delivery capacity. Experts believe that Xinjiang's energy industry must make breakthroughs as soon as possible in order to achieve rapid development

energy treasures hide in isolated islands

the imbalance between energy distribution and energy demand is China's basic national condition. Xinjiang is located in the hinterland of the Eurasian continent, bordering eight countries such as Mongolia and Russia. As an important strategic energy reserve base in China, Xinjiang is rich in oil, natural gas, coal, coalbed methane, hydropower, wind energy, solar energy and other resources, ranking in the forefront of the country

at present, the predicted coal reserves in Xinjiang are 2.19 trillion tons, accounting for 40% of the total predicted nationwide, ranking first in the country; The prospective reserves of oil resources are 21.3 billion tons, accounting for 20% of the total onshore resources in China; The prospective reserves of natural gas resources are 10.84 trillion cubic meters, accounting for 32% of the total onshore resources in China; Xinjiang, with 570 rivers, has a total water resource of 83.2 billion cubic meters, and the exploitable capacity of hydropower technology is about 16.57 million KW, ranking fourth in the country; The total reserves of wind energy resources in Xinjiang reached 886million kW, and the technical exploitable capacity was 120million kW, ranking second in the country; Xinjiang has a long sunshine time throughout the year, and the total annual irradiance is 10%~15% higher than that of China at the same latitude, second only to Tibet, ranking second in the country. Solar energy has great development potential

by the end of 2008, the annual raw coal output of Industrial Enterprises above Designated Size in Xinjiang was 60.6392 million tons, and 8.3 million tons were transferred, accounting for 13.69% of the coal output of that year; The output of crude oil was 8.61 million tons, accounting for 31.71% of the crude oil output that year; The production of natural gas was 23.603 billion cubic meters, and the output was 15.7 billion cubic meters, accounting for 66.52% of the total output of that year. The output and export volume ranked first in the country for four consecutive years; Remarkable achievements have also been made in the construction of the power industry, with a total installed power generation capacity of 10.8979 million KW and a power generation capacity of 48.9 billion kwh; It has achieved 220 kV connection across Xinjiang and built the 220 kV power supply with the largest coverage in the world

with the completion of Kazakhstan Atasu Xinjiang China crude oil pipeline, China also imported crude oil from abroad in the form of pipeline for the first time. With the strong support of the state, Xinjiang's energy industry has initially formed a complete industrial system, and its ability to balance the domestic energy market has been continuously improved. The export of energy such as oil, natural gas and coal has strongly supported the national economic construction

despite the rich resources, the energy development in Xinjiang is not plain sailing. At present, the proven degree of oil and natural gas in Xinjiang is 17.2% and 11.89% of the predicted total amount respectively, which is far lower than the national average level. While the structure of coal mining and power production is unreasonable, a large number of food in various countries have become garbage that needs to be treated due to expired deterioration, and the situation has not been completely improved. There are relatively many small and medium-sized coal mines, and the level of equipment assembly is low

in power production, 100000 kW and above units account for only 43.3% of the total installed capacity of thermal power in Xinjiang. Although the unit capacity of thermal power in Xinjiang has reached 300000 kW, there is still a big gap compared with other regions. The correlation between oil and gas development and local economy is not high. In 2008, Xinjiang's natural gas transmission from west to East was 15.7 billion cubic meters, accounting for 66.52% of the total output that year. The natural gas supply allocated to the autonomous region could not meet local demand, resulting in seasonal gas shortages in Urumqi and other cities

the main obstacle restricting the development of Xinjiang's energy industry is that the construction of energy delivery channels is not perfect, and large-scale delivery is difficult. At this stage, in terms of energy transmission channels, Xinjiang has only built railways, highways and oil and gas pipelines, and the power transmission channels are still under construction. The transportation capacity of Railways and oil and gas pipelines can not meet the requirements of energy export in Xinjiang. The transportation capacity of Lanzhou Xinjiang Railway can only provide 30% of the coal output. Therefore, it is difficult to transport coal from the west to the East on a large scale, and the journey of transmitting electricity from the west to the East is long

former substitutes turned into main players

in recent years, with the national economy maintaining near double-digit high-speed growth, energy demand is increasing day by day. The central and eastern region has a strong demand for oil, gas and coal resources, and the external dependence on energy remains high. The country began to gradually shift the strategic focus of the development of oil, gas, coal and electricity to the West. In 2007, the State Council issued a document clearly proposing the strategic goal of building Xinjiang into a national large-scale oil and gas production and processing base, a large-scale coal base, an important petrochemical industry base, a national demonstration base for the large-scale utilization of renewable energy, and a land-based safe passage for imported energy and scarce mineral resources. The growing demand for energy in China's economic development has led Xinjiang's energy development from behind the scenes to in front of the stage, gradually changing from a substitute in China's energy field to a main player

under the guidance of national macro policies, Xinjiang's energy resources have changed the old development mode of small-scale fighting, vigorously implemented the strategy of transforming advantageous resources, followed the road of new industrialization, and opened its mind to attract large enterprises and groups at home and abroad to go west to participate in the development of coal mining, coal power, coal chemical industry, coal coking, hydropower, wind energy and solar energy

at present, the five major domestic power generation groups and the top 20 coal enterprises have all settled in Xinjiang. The diversification of energy investment subjects has initially changed the pattern of resource development and utilization in Xinjiang, which is dominated by coal and crude oil, promoted the comprehensive start of the transformation strategy of energy and resource advantages, and improved the scale, quality and efficiency of the energy industry

experts predict that by 2020, the coal gap in China's mainland will be more than 1.5 billion tons, and the total power gap in northern, central and eastern China will be about 300million kW. This provides a broader space for the development of Xinjiang's energy industry

therefore, the autonomous region has proposed to speed up the development of energy industry, build the energy industry into a pillar industry of the autonomous region as soon as possible, rely on advantageous resources, implement the development strategy of four-way drive of coal, electricity, oil and gas, steadily build large-scale coal and coal electrification Bases Based on coal development, combined with the development of coal electricity, coal chemical industry and other industries, enhance the strategic position of Xinjiang's coal, and form coal and coal chemical industry, electricity, natural gas The production and export base of petroleum and petrochemical products, diversified development, deepening utilization, expanding export, transforming Xinjiang's energy resource advantages into economic advantages, establishing Xinjiang's important strategic position in China's energy industry, and meeting the national energy and Xinjiang's development and construction needs

reconstruction of energy chess game by coal power transmission

the "Research on the medium and long term development planning of energy in Xinjiang Uygur Autonomous Region" issued in 2009 shows that in the future, while ensuring the supply of coal in the autonomous region, Xinjiang will focus on meeting the needs of other regions for coal, coal power and coal chemical products, focusing on the four coalfields of Zhundong, Tuha, Yili and kubai, and build six large coal bases, including Hami, Zhundong, Yili, zhunbei, Tabei and Zhunnan, Build the most important coal production center in Western China

the coal chemical industry will focus on the conversion of coal to oil, coal to methanol to dimethyl ether or olefins, and coal to natural gas, develop new coal chemical industry, reduce dependence on oil, and ensure national energy security. While increasing the intensity of coal conversion, expand the railway transportation capacity and form a coal transportation channel between the north and South wings. The south wing mainly supplies Sichuan and Chongqing, and the North Wing mainly supplies Hubei, Hunan, Jiangxi and other places. It is planned to achieve an annual delivery capacity of 100 million tons in 2015

on the basis of expanding the scale of oil and gas exploitation in Xinjiang and increasing oil and gas production, we should strengthen foreign oil and gas cooperation, based on the rich oil and gas resources in Central Asia and Russia, speed up the development of natural gas resources in Central Asia, build the second phase of the China Kazakhstan oil pipeline due to damage accumulation and the second line of the west east gas transmission, plan to build the third and fourth lines of the west east gas transmission, and strive to basically build Xinjiang crude oil, refined oil and natural gas pipelines by 2020

relying on the construction of coal bases, build Zhundong, Tuha and Yili thermal power bases to realize the joint production of coal and electricity. According to the power supply construction plan of Xinjiang, it is estimated that the total installed capacity of Xinjiang in 2015 will reach 34.6 million to 39.5 million KW, with the maximum outward power of 9.2 million KW. In order to optimize the allocation of resources in a wider range and increase the proportion of electricity in energy output, Xinjiang is implementing the strategy of ultra-high voltage, large units, high parameters and large electricity, actively participating in the west to East power transmission, vigorously promoting the construction of 750 kV power and the pace of Northwest Power connection, so that power production and export have become an important means of transforming Xinjiang's advantageous resources

with the strong support of the State Power Corporation, six 750 kV power transmission and transformation projects in Xinjiang in 2009 have been approved by the national development and Reform Commission, and three projects have been approved and started construction. Xinjiang's first 750 kV Urumqi Turpan Hami power transmission and transformation project has been completed and will be connected with northwest power within this year. As an important rear area of energy resources in China, with the implementation of the strategy of transforming advantageous resources and the strategy of large enterprises and groups, Xinjiang has gradually turned the remote supply rear area into a frontier base for intensive processing. From the west east gas transmission, west east coal transportation to the west east power transmission, Xinjiang is forming a diversified pattern of energy resource development

invest 1.5 billion yuan to promote mineral exploration in Xinjiang

this year, China will invest 1.5 billion yuan to continue to promote the exploration of important minerals such as coal, iron, copper, lead and zinc in three mountains and two basins in Xinjiang, so as to provide sufficient resource guarantee for China's economic and social development

according to the Department of land and resources of Xinjiang Uygur Autonomous Region, this year, the state and autonomous region finance will continue to invest 1.5 billion yuan, focusing on the integrated exploration of western coal and Eastern Coal Transportation bases such as Tuha and ILI, as well as important metallogenic prospects such as Awulale, Tashkurgan, Qimantag, and strive to discover 30 new ore producing areas, and add 500 million tons of iron ore resources, 1 million tons of copper, 3 million tons of lead and zinc, 300 billion tons of coal, etc. Driven by the strong financial investment of the central and autonomous regions, this year's mineral exploration in Xinjiang is expected to attract 20 billion yuan of social funds for the design stage of products

in order to promote the process of geological survey in Xinjiang, in July 2008, the Ministry of land and resources signed an agreement with the people's Government of Xinjiang Uygur Autonomous Region to jointly carry out public welfare geological survey and important mineral exploration projects in Xinjiang, striving for good projects in three years, encouraging results in five years and significant results in eight years, so it is referred to as 358 project. The project was officially launched in 2009, with a total investment of 994 million yuan, 186 new and continued projects, 111.7 billion tons of new coal resources in Turpan Hami basin, 30million tons of new potash resources in Lop Nur, and 175 million tons of new iron ore in Hejing county. The mineral exploration results are rich. (Li Yifeng)
