神木-依拉克地区构造研究新进展

New progress in the study of Tectonics of Shenmu area

勘探程度较低的神木地区在获得工业油气流之后,已经跻身塔里木盆地油气勘探的重要地区之一。但在进入钻井阶段后取得的成果并不尽如人意,在神木3、4井钻探失败的背景下,对神木-依拉克地区的构造进行了更深一步地研究,勘探方向由之前的"以构造思路"进行勘探转换为"以岩性油气藏思路"进行勘探。对区块内的圈闭进行精细构造落实,发现并重新落实了5个圈闭;同时也对区块内沉积情况进行进一步的认识,发现神木-依拉克地区发育多种类型油气藏。

The Shenmu area with low exploration level has become one of the important areas for oil and gas exploration in the Tarim Basin after obtaining industrial oil flow.However,mo good results were achieved during the drilling.Because the drilling of Shenmu 3 and Shenmu 4 failed,we further studied the structure of the Shenmu area.The exploration direction is transformed from exploration with structural ideas to exploration with lithologic reservoir ideas.After a detailed study of the traps in this area,and five traps were discovered and re-implemented.At the same time,the sedimentation in the block was further recognized,and many types of oil and gas reservoirs were discovered in the Shenmu area.
