摘要: 塔北为大型古隆起控制油气区域性聚集,它与生油坳陷紧邻,油气源充沛;古隆起上的大型凸起、重叠复合构造、不整合面、断裂、地层楔形体,对油气运移、聚集和分布有不同的控制作用。沙雅隆起具有纵向上的三层结构特征和横向上的三大油气聚集领域。

Abstract: Shaya uplift in North Tarim Region is situated between Amang and Kuqa oil-generating depressions with rich hydrocarbon source.Oil and gas accumulation is con-trolledby the large embossment,stratigraphic wedges,superposition structures and local structures developed on the uplift.The pool-forming model is considered to be:1.Three-layer structure in vertical.The upper one is composed of Meso-Cenozoic sandstone and characterized with secondary accumulation;the middle one is composed of Middle-Upper Paleozoic sandstone in wedge-shape,and characterized with primary and secondary accumulation;the lower one is composed of percolation bed and interior layer of weathered crust in Lower Paleozoic carbonate rocks,and characterized with primary accu-mulation. 2.Three accumulation fields in lateral including(1)the superimposed area of upper and lower structural layers in the north part of Shaya uplift;(2)the superimposed area of Upper-Middle Paleozoic wedge between two unconformities in the margin of the uplift;(3)three completely superimposed area in the south part of the uplift.
