摘要
Summary name="EnDivSummary">Based on the analysis of core, mud log, Inspection, well logging and other information, the relationship has been established between well logging curve and the sedimentary microfacies by using the self-potential, natural gamma, resistivity and acoustic logging. The type and characteristics of well logging curve shape in different sedimentary microfacies also have been described. Microfacies of the H1 Formation have been researched from three different level of single well, section correlation and planar distribution. The results show that oil-bearing layers of the HSS oilfield are river-delta depositional system, mainly including of delta front and shoreward lake sub-facies. The shapes of well logging curves corresponding to subaquatic distributary channel show as cylinder or bell-shape, corresponding to mouth bar as reversed cedar shape, to front sheet sand mostly as dentate shape, and to shore-shallow lake as dentate or finger-like shape.
