吐哈盆地北部山前带紧邻胜北、丘东、小草湖三大生油气凹陷。南北为近物源沉积,发育多套储盖组合。经历燕山期、喜山期等多期构造运动,从北至南发育逆掩带、背斜带和斜坡鼻隆带,油气多期运聚成藏。目前,已发现鄯勒、恰勒坎、柯柯亚、玉果、七泉湖5个油气田,6套层系获得工业油气流,证实为复式油气聚集带。燕山期古构造、现今构造高点、断层、储层、盖层等控制了油气藏的形成与分布。下一步应在积极拓展J2s主力油气藏的同时,加强水西沟群J1-2sh油气藏的勘探及中—东段浅层油气藏的勘探。
Turpan-Hami basin piedmont belt adjacent to the north, Qiu Dong, Grass Lake San Dasheng depression. Near the source sediment deposition, the development of multiple sets of storage cover combination. Experience Yanshanian, Himalayan and other multistage tectonic movement, from north to south developed reverse belt, anticline and slope of the nose uplift, oil and gas migration and accumulation. At present, it has been discovered that 6 oil and gas fields of Langle, Qialekan, Kekeya, Yuguo and Qichuang have obtained industrial oil-gas flow and are confirmed as oil and gas accumulation zones. Yanshanian paleostructures, present-day structural highs, faults, reservoirs and cap rocks control the formation and distribution of oil and gas reservoirs. The next step should be actively expanding J2s main oil and gas reservoirs at the same time, to strengthen the exploration of Jixihugou J1-2sh reservoir and exploration of the middle-eastern shallow reservoirs.
