摘　　要：通过对北天山山前主要目的层储集层基本特征、成岩作用及影响储集层物性的主要因素等综合分析研究，认为该区各储集层的演化严格受区域及局部构造运动、沉积展布、成岩作用的制约。不利沉积相带、碳酸盐胶结及自生粘土矿物析出等是影响储集性能的不利因素；有利因素为溶蚀、环边泥膜及早期碳酸盐胶结物支撑。指出安集海塔西河组（N1t）、独山子沙湾组（N1s）、呼图壁紫泥泉子组（E1－2z）及玛纳斯安集海河组（E2－3a）为较好储集层。Comprehensive analysis for principal target strata in piedmont of northern Tianshan Mountain is conducted including the studies of fundamental characteristics of reservoir diagenesis and other important factors affecting the petrophysical properties of reservoir． It is recognized that the evolution of various reservoir is strictly constrained by regional and local tectonic movements deposits distribution and diagenesis． The unfavorable factors affecting reservoirs are the unsuitable sedimentary facies belt where they situated carbonate cementation and the separate out of autogenetic clay minerals etc． while the favorable conditions are denudation peripheral mud film and carbonate cements supporting in earlier stage． The paper indicated that the relatively good reservoirs are Taxihe formation(N1t) of Anjihai Shawan formation(N1s) of Dushanzi Ziniquanzi formation(E1－2z) of Hutubi and Anjihaihe formation(E2－3a) of Manasi．
