摘要

英买力地区碳酸盐岩基质孔隙度低、渗透性差,很难提供良好的储集空间,但由于其后期长期或多次出露地表遭受淋滤剥蚀和近地表岩溶作用,使碳酸盐岩中裂缝、溶蚀孔和溶蚀洞发育,形成了良好的古风化壳储层且主要分布在潜山顶面以下的风化壳带内。研究表明:来自库车坳陷丰富的湖相烃源岩油气,经大范围分布的古生界与中生界之间的不整合面提供的运移通道和下第三系与白垩系之间或侏罗系、三叠系砂岩疏导层向南运移,到达英买力地区碳酸盐岩古风化壳储层后,受到上覆白垩系卡普沙良群泥岩的封盖而聚集成藏。

Abstract

The matrix with low porosity and permeability in the carbonate reservoir in Ying maili area can not provide effective reservoir space, but because of the croppin g out long time or many times, they suffer leach, denudation and karsification n ear surface, so in carbonate the fracture, solution hole and solution cave have  developed. They form the paleoweathering crust reservoir. And they mainly distri bute the weathering crust belt beneath the superface of the burial hill. We have  worked out the oil and gas coming from the great of lake faces source in Kuche  depression pass through the migration pathway which is the unconformity surface  of paleontology and Mesozoic group and the carrier bed between the Paleogene Sys tem and cretaceous or the Jurassic and Triassic sandstone. At last they arrive t he carbonate paleoweathering crust reservoir and accumulate beneath the cretaceo us Kapushaliang mudstone. 
