摘要
Ordovician carbonate oil and gas reservoir forming conditions is superior in Yingmaili region.Yijianfang and Yingshan Formation as the main quality reservoir horizon,the distribution of reservoir has obvious difference.Through the cores,flakes,logging and testing data,this article analized the Ordovician carbonate rock reservoir.The results shows that it is mainly flat sparry grain limestone and argillaceous limestone particles in Yijianfang Formation,grain limestone and micrite interactive distributed in Yingshan Formation.The reservoir space is mainly structural cracks and holes,the reservoir type is mainly pore fracture type and fracture type.Sedimentary facies belt control material basis,contemporaneous period atmospheric fresh water dissolution,burial dissolution and tectonic action made reservoir connectivity well,reservoir space increases,forming good reservoirs.Dissolution and tectonic movement is the key factors of the reservoir’s distribution.
