伪声阻抗在碳酸盐岩储层研究中的应用

APPLICATlION OF PESUDO-ACOUSTIC IMPEDANCD IN STUDY OF CARBONATE RESERVOIR

本文介绍利用伪声阻抗研究碳酸盐岩储层孔隙物性的方法,以L油田为例,做了伪声阻抗剖面,将其与井的声阻抗速度和孔隙度测井资料进行相关对比分析。进而对伪声阻抗剖面做孔隙度标定,最终获得孔隙度解释剖面和储层厚度加权平均孔隙度平面图等成果。

Coauthors developed a technique of utilizing pesudo-acoustic impedance sections to study carbonate reservoir quantitatively. Subsequently,they are employed in L oil field,compared corr- elatively with sonic,velocity and porosity logs,and calibrated in porosity.Finally porosity cross sections and planar variation map of thickness-weighted porosity are made with the technique.
