塔里木盆地东部超深层油气勘探快速实现新突破

Rapid achievement of new breakthroughs in ultra-deep oil and gas exploration in eastern Tarim Basin

塔里木盆地东部蕴藏着丰富的油气资源,是我国陆上油气资源增储上产的重点地区。在国家油气勘查开采体制改革、新一轮找矿突破战略行动等政策背景下,中央-地方-企业紧密融合新机制助推了油气勘探开发快速实现突破的新模式,带来了极大的经济效益和社会效益。创新优化制定了塔东尉犁西1区块勘探部署方案,实现了8000 m以深地质层位设计和实钻对比“零”误差,取得了信源1井、信源2井、信源3井超深层油气重大发现。同时,形成了一系列科技创新成果,提高了超深层地质体识别精度,形成了地质工程一体化技术体系,明确了缝洞型储层发育区,形成了2亿t级规模超深层油气富集新区。新机制新模式开辟了“十四五”油气增储上产新领域,奠定了塔东油气资源接续基地建设基础,推进了新一轮找矿突破战略行动目标的实现。

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 significant 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 drilling comparisons,and making major discoveries of ultra-deep oil and gas in Well XY1,XY2,XY3.A series of technological 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 mechanism 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.
