【摘要】 柴西南地区深部成藏组合勘探程度低,勘探潜力大,可划分为5个正向构造带,其中新区昆北断阶带切6井已获得重大突破,狮子沟—油砂山构造带和乌南斜坡也具有一定的潜力。柴西南地区红狮、跃进、乌南斜坡岩性勘探领域具有良好的勘探前景,并在乌南斜坡取得了重要进展。柴北缘地区中、下侏罗统分布广,厚度大,但优质烃源岩的分布相对局限,冷湖—南八仙构造带、鄂博梁构造带及南祁连山前带为勘探的有利区带。更多还原

【Abstract】 The level of deep reservoir combination exploration in the southwestern part of Qaidam basin is lower and potential of exploration is big,and five positive structural belts can be divided in that region,among which the Qie-6 well in Kunbei fault terrace of new area achieved breakthrough,Shizigou-Youshashan structural belt and Wunan slope also have some potential.Good exploration prospect is in the field of lithologic exploration in Hongshi,Yuejin and Wunan slopes of the southwestern part of Qaidam basin and important progress has been achieved in Wunan slope.The northern margin area of Qaidam basin is characteristics of wide Middle and Lower Jurassic distribution and having thicker thickness,but relative limited distribution of good quality of hydrocarbon source rock,Lenghu-Nanbaxian structural belt,Erboliang structural belt and South Qilian Mountain piedmont zone are favorable zones for exploration.更多还原
