Abstract
Core observation and indoor thin section analysis as well as other technical means systematically studies the clastic reservoir rock characteristics of Shiwu Fault Depression.The study found that Shiwu Fault Depression deep buried clastic are composed mainly by fine sandstone and medium sandstone,and grain size are mainly controlled by sedimentary facies.Interstitial material is mainly carbonate and shale,secondly kaolinite.These characteristics provide a petrology foundation for accurately predicting the reservoir’s development of favorable zones in this region, and for further developing the deep buried clastic accumulation regularity.
