摘要：

上震旦统克孜苏胡木组主要为近滨、前滨、藻坪和潮坪四个亚环境。其中二、四段的残余凝块石粉(泥)晶白云岩、粉泥晶白云岩等分别经历了白云石化作用、溶解作用、胶结作用和新生变形作用。溶解作用、白云石化作用为凝块石白云岩产生了有利的储集孔隙。物性资料显示,残余凝块石粉(泥)晶白云岩具有良好的储集性能。

Abstract:

The Kezisuhumu Formation in the Upper Sinian is composed of carbonate rock and terrigenous detrital rock deposited in coast envirgnment,which could be subdivided into shoreface,foreshore,algal flat and tital flat subenvironment.Thormbolite-dolomitite in the algal flat and micro-dolomite in the tidal flat underwent dolomitization,dissolution,cementation and neomorphism.The porosity in the thormbolite-dolomitite was speedy de-clined by the cementation,but the reservoir spaces were produced by the dissolution,dolomitization and neomorphism.The analysis results of physical property for the thorm-bolite-dolomitite shows that the rock has good reservoir property.
