摘要
当用电阻率、孔隙度测井信息根据阿尔奇公式计算泥质砂岩储集层的孔隙度指数m时,由于其中泥质的影响,不可避免地会使计算结果存在一定误差.本文通过分析泥质砂岩的导电性,提出了一种改进方法。
The porosity exponent m estimated according to electrical porosity log has some errors due to shale influence. This paper analyzes the electrical characteristics of shaly sands andproposes an improved method.
