摘 要：SHA1 is the representative reservoir in Liao He *** the introduction of curvature displayed on the gray scale,we determine the substructure and *** inversion method is used to help study the porosity of *** relationship between interval transit times and resistivity among mudstone and sandstone,before and ater water injection,is *** relationship between porosity and permeability and the relationship between porosity and impedance from core analysis were *** the whole information above,we divide the microfacies of SHA1 reservoir to distributary channel,mouth bar,the leading edge thin sand,and prodelta *** water injections in diferent microfacies are *** distributary channel should be used by large distant injection wells or smaller injection pressure *** smaller distant injection wells or large injection pressure should be used in the mouth *** arrangement of well injection need consider the diferent sedimentary microfacies.
