摘　　要：塔河油田C区是近年在油气勘探史上的又一重大突破。该区主要储、产油气层为下奥陶统 ,其储层属于潜山碳酸盐岩储层类型 ,具有较强的非均质性。塔河油田C区奥陶系油藏正处于开发初期阶段 ,动态资料尚少 ,根据油田地质情况、油藏类型及拥有的实际资料特征 ,笔者采用经验公式法、表格估算法及类比法The discovery of Block C of the Tahe Oil Field, Xinjiang marked a recent breakthrough in the oil and gas exploration in northwestern China. The source and reservoir rocks in the oil field consist dominantly of the Lower Ordovician strata , that may be assigned to the buried hill type carbonate reservoir rocks. The reservoir rocks are nonhomogeneous and undersaturated, and characterized by low porosity and constantly changing permeability. The primary recoveries of the Ordovician hydrocarbon reservoirs in Block C of the studied oil field have been determined with the aid of empirical formula , tables and analogy analysis on the basis of geology, reservoir type and available information.
