摘　　要：针对营７２断块沙三中亚段储层特征，通过岩电分析，确定选用Ｗｙｌｉｅ公式作为声波时差到孔隙度转换的基础。根据储层岩石学特征确定公式参数值，并用岩心分析孔隙度与Ｗｙｌｉｅ公式计算孔隙度重叠逼近法确定校正系数Ｃ。Based upon reservoir characteristics of the middle sub member of the third member of Shahejie Formation in block Ying 72, and lithology electricity analysis, Wyllie equation is determined to be used for the basis of transmission from interval transit time to porosity. The parameters in the equation are determined through reservoir lithologies. The correction coefficient C is determined by the overlay and approximating of porosity derived from core analysis and porosity calculated by Wyllie equation. Finally, the interpretation model for porosity in consolidated sandstone reservoir is set up.
