摘要： 塔里木盆地塔中地区Ⅰ号断裂带上奥陶统良里塔格组为目前国内较典型的碳酸盐岩油气储集层，且有巨大的勘探潜力，深入研究该套储集层的类型及分布对塔中地区的下一步勘探将具有重要的指导意义。通过大量岩心分析，根据孔隙度—渗透率相关关系将塔中地区Ⅰ号断裂带上奥陶统良里塔格组碳酸盐岩储集层划分为3 种主要类型：孔隙型、裂缝型、裂缝—孔隙型。根据各单井储集层类型，结合沉积相及断裂等储集层影响因素，推断了良里塔格组3个岩性段的不同类型储集层的分布范围，认为裂缝型储集层最为发育，而最有利于油气成藏的裂缝—孔隙型储集层主要发育于良二段，孔隙型储集层分布范围较小。最后认为塔中Ⅰ号断裂带塔中82井区—塔中24井区为油气勘探最有利区。

Abstract: The Upper Ordovician Lianglitage Formation is one of the typical carbonate reservoirs in China and has a considerable exploration potential. Therefore， further studies of the types and distribution of this reservoir have a great significance in guiding the next step of exploration in the Tazhong area. Based on the analyses of core data and the relationship between porosity and permeability，the carbonate reservoir of the Lianglitage Formation in the Upper Ordovician in Tazhong No.1 fault belt has been studied and is divided into three types:pore type，fissure type and fissure-pore type. According to the reservoir types of individual wells in different formations，combined with the controlling factors of the reservoirs，including sedimentary facies，fracture and so on，the distribution of individual type reservoir is determined for the three different formations. The fissure-type reservoir is widely distributed. The pore types distribution is narrow in this area. The fissure pore type which is the most favorable type for petroleum accumulation was mainly developed in the Member 2 of the Lianglitage Formation. Finally，The Tazhong well 82 and Tazhong well 24 areas are predicted to be the favorable exploration zones for the Upper Ordovician in Tazhong No.1 fault belt.

Key words: Tarim Basin, Tazhong area, Upper Ordovician, No.1 fault belt, reservoir type, carbonate rock
