川东石炭系气藏开发地质模式研究

A STUDY OF GEOLOGICAL MODELS FOR RESERVOIR EXPLOITATION IN CARBONIFEROUS OF EASTERN SICHUAN

通过对川东各气藏储层特征、测试资料、开采资料的系统研究，采用静态、动态相结合的方法，将川东石炭系气藏分为高渗型气藏、中渗型气藏、低渗型气藏、非均质气藏。分别论述了各类气藏的储层特征、开采特征，在此基础上建立各类气藏储层分布模式、开采特征模式。

The Carboniferous gas reservoir iS the major gas exploitation base in eastern Sichuan.Basedon a systematic study of reservoir characteristic, test data, recovery data,production data and by themethod of combining static performance with developing performance,the reservoirs can be classifiedinto high permeability, middle Permeability,low permeability and nonhomogeneous reservoirs. Distribution pattern and production model of each reservoir have been established. The practice shows that themodels established here can predict the exploration and exploitation of the Carboniferous reservoirs andlay the foundation for building prediction models.
