塔里木盆地多旋回、不均衡构造运动和沉积演化导致油气成藏和分布非常复杂,近年来随着局部地区地质认识的不断深入,有必要加强系统的成藏规律研究。据已发现油气藏的成藏特征可建立7种油气成藏模式,即前陆盐下挤压背斜气藏、前陆盐上构造—岩性残余油藏、前陆前缘斜坡构造—岩性油气藏、台盆古隆起碳酸盐岩风化壳—层间岩溶立体组合油气藏、台盆古隆起碎屑岩复合油藏、台盆长期斜坡浅层反转构造—岩性油气藏和台盆长期凸起深层构造—岩性残余油藏成藏模式。通过对不同构造区域和构造层的成藏模式特征及分布规律分析认为,除了库车坳陷、塔北隆起和塔中隆起是油气增储上产三大主战场外,塔西南坳陷、库车西秋里塔格地区、台盆区志留系—三叠系、盆地东部低凸起斜坡是下一步勘探的重要方向。
In the Tarim Basin, multi-cycles, unbalanced tectonic movement and sedimentary evolution have resulted in very complicated hydrocarbon accumulation and distribution. In recent years, with the continuous deepening of geological understanding in some areas, it is necessary to study the law of hydrocarbon accumulation. According to the reservoir forming characteristics of the discovered reservoirs, seven kinds of hydrocarbon accumulation models can be established, namely, the foreland salt crustal anticline gas reservoirs, foreland salt structural-lithologic residual reservoirs, foreland foreland slope structures-lithologic oil and gas Permian paleo-uplift Carbonate weathered crust - interlaminar karst combination reservoir, basin paleo-uplift clastic composite reservoir, basin Long-term slope shallow inversion structure - lithologic reservoir and basin Long term Raised deep structure - lithologic residual reservoir accumulation mode. Based on the analysis of the characteristics and distribution patterns of hydrocarbon accumulation modes in different tectonic zones and structural strata, it is considered that except for the Kuche Depression, the Tabei uplift and the Tazhong uplift are the three major battlefields for oil and gas accumulation and production increase, In the western Qiliettag area, the Silurian-Triassic basin in the basin area and the low-convex slope in the east of the basin are the important directions for further exploration.
