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.
