四川盆地南部寒武系碳酸盐岩储层类型及发育分布特征研究

Study on carbonate reservoir feature in south area of Sichuan basin

储层基本特征认识是分析和研究储层的重要基础之一,针对川南地区寒武系碳酸盐岩储层,前人对储层基本特征的总结尚显不足,由此,本文通过钻井岩芯、岩屑及其薄片观察,三汇场、岩孔、范店3个野外剖面储层综合解剖,岩芯及物性综合整理分析的基础上通过储层的岩石类型及岩石学特征、储渗空间类型与储层类型特征、储层发育分布特征等几个方面总结认识了区内碳酸盐岩储层特征。

Reservoir characteristics is one of the important basis in our analysis and research of reservoir.On Cambrian carbonate reservoir in south area of Sichuan basin,previous summary of the basic features of the reservoir is still inadequate.In this article,based on comprehensive analysis of drilling core,cuttings and thin section observation,three field,rock hole,fan shop three field profile,core and physical property,through the reservoir rock types and petrological characteristics,reservoir space types and the distribution characteristics of reservoir type,reservoir characteristics and so on,summary the regional characteristics of carbonate reservoir.
