摘要： 中古15井区与塔中其他区块奥陶系良里塔格组礁滩体储集层发育层位存在差异性，主要发育于良三段滩相颗粒灰岩，其次为灰泥丘隐藻泥晶灰岩，储渗空间主要为孔洞、大型洞穴和裂缝，且基质为低孔低渗型储集层；根据薄片、成岩组构和微量元素等资料综合分析认为，储集层的形成主要与良三段沉积时期发生过礁滩体岩溶和后期埋藏岩溶作用的改造密切相关。

Abstract: The Ordovician Lianglitage formation in Zhonggu?15 well area of central Tarim basin is of reef?flat karst reservoir, but different from other areas in this basin in horizon. It is mainly distributed in grain limestone bank of reef?flat facies of the third member of Lianglitage formation, and then in algal?laminated cryptite in lime mud mound. The main reservoir spaces consist of vug, cave and fracture, belonging to low?porosity and low?permeability reservoir. In accordance with the data analysis of the thin?section, diagenesis texture and microelements, it is recognized that the reservoir formation is closely related to the reef?flat karst and late burial karst reconstruction in the period of the third member deposition
