摘要
This paper studies the reservoir characteristics and main controlling factors of the Jia5 member,Triassic Jialingjiang Formation,and identifies two types of reservoir rocks,silt-sized crystalline dolomite and calcarenite.The silt-sized crystalline dolomite reservoir developed in the dolomite-flat microfacies has a good pore/throat configuration with intercrystalline pores and dissolved pores as reservoir space.The research on the main controlling factors of the reservoirs indicated that they are typically facies-controlled reservoirs.Microreliefs inside the carbonate platform lead to high heterogeneity of the reservoirs.Dolomitization and the leaching of syngenesis meteoric water are the key factors for forming good porous carbonate reservoirs.
