摘要

通过沉积相、测井相、地震相的综合研究,认为四川中江地区沙溪庙期为河流-湖泊相沉积环境,从早至晚经历了浅湖→半深湖→湖底扇→三角洲→曲流河环境演化过程。根据不同时期沉积微相特点及平面展布,指出了有利的含气砂体相带。

Abstract

Based on a synthetic study of sedimentary facies,logging facies and seismic facies,Shaximiao formation in Zhongjiang area,Sichuan province was considered to be deposited in a fluvial-lacustrine environment.It underwent evolution process of shallw lake,semi-deep lake,sublacustrine fan,delta to meande ring stream environments from early to late periods.The favourable zone for gas accumulation was pointed out according to the characteristics of sedimentary microfacies in different periods and their distribution.
