Characteristics and controlling factors of reservoir in Sinian Dengying Formation,Sichuan Basin,China
摘要
Abstract
Dengying Formation of Sinian is one of the most important gas-bearing strata in Precambrian of China.Based on the lithology characteristics,the scanning electron microscope,the cathode luminescence and some other experimental analyses,this paper studies some samples taken from the outcrops and the drilling cores of Dengying Formation in Sichuan Basin.This paper studies the dolomite reservoir of Dengying Formation.The types of the dolomite reservoir are mainly the algal stromatolite dolomite,algal lamellar dolomite,algal dolarenite,algal oncolite dolomite and algal grumous dolomite,and so on.There are altogether 6 kinds of reservoir pore spaces in Dengying Formation.Among them,the interbreccia pores,the mass dissolved pores-caves and the “grape-lace”remnant pores-caves are very important.The Development of the dolomite reservoir is mainly controlled by sedimentary facies,dolomitization,dissolution,sea level ecstasy and tectonic action. The sedimentary facies is the environment basement of the reservoir.The dolomization is the key that the reservoir can be preserved.The dissolution,sea level eustasy and tectonic action are the key factors to make pore spaces.The tectonic fracture is an important factor to improve the reservoir.The cementation and silicification will fill the pores and are destructive factors for the reservoir in Dengying Formation.关键词
