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 types 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.
