Research On Gas Reservoir Of Shanxi Formation In Southeast, Ordos Basin

Based on theories of sedimentology. petroleum geology, reservoir geology, tectonic geology, geomathematics and logging geology, taked computer and the automatic plotting technology as the method, used the modern reservoir conditions theory as the instruction, combined with the data of geologic control, geophysical well logging, analytical and reservoir testing, the fine compartmentalized and parallelled of Shanxi formation fine explaining of contexture, diagenesis and porosity evolution, dividing types of sedentary microfacies the plane distribution characteristic of sedentary microfacies evolutionary rule of sedimentation and distributing of frame sand are researched from rock and key well analysis. In this article, physical property, pore structure and their nexus,heterogeneity of reservior rule are also studied. Futher more.the interpretational criteria of reservoir parameters. Reservoir sensitivity and heterogeneity are evaluated. Based on the research of reservoir character and conditions, plane graphs of sections tectonic, sedimentology and reservoir parameters mapped by geology software.The research above will contribute to development program, technical policy and reservoir research.
