Rapid achievement of new breakthroughs in ultra-deep oil and gas exploration in eastern Tarim Basin
Eastern Tarim Basin is rich in oil and gas resources and is a key region for reserve growth and production addition of land oil and gas resources in China.Under the institutional reform of national oil and gas exploration and exploitation and new round of mineral exploration breakthroughs strategic actions,the close integration of central and local grovernment and enterprises has promoted a new model of oil and gas exploration and development,bringing sig-nificant economic and social benefits.The formulating exploration deployment plan for Yuli west 1 block was innovated and optimized,achieving a"zero"error in the design of geological horizons deeper than 8,000 meters and actual drill-ing comparisons,and making major discoveries of ultra-deep oil and gas in Well XY1,XY2,XY3.A series of tech-nological innovations have been made,which improved the accuracy of ultra-deep geological body identification.And an integrated technical system of geological engineering formed.The development area of fractured-cavity reservoirs was clarified,and a 200 million ton-scale ultra-deep oil and gas accumulation area was discovered.This new mech-anism and new model opened up a new area for reserve growth and production addition of oil and gas in the 14th Five-Year Plan period,which laid the foundation for the oil and gas resource succession base construction in eastem Tarim Basin and promoted the goals achievement of the new round of mineral exploration breakthroughs strategic actions.
