摘要
关于孔隙度指数m值的研究,一直是测井界的热点问题.基于国内外测井研究人员对孔隙度指数m进行的大量探索和研究,对各种方法进行了分析总结.从最初的只有粒间孔隙的砂岩模型的孔隙度指数m值,到后来根据双重孔隙模型确定孔隙度指数m值,现在发展到根据三重孔隙模型确定孔隙度指数m值.可以看出,随着油气勘探形势的严峻,孔隙模型越来越复杂,对储层的描述越来越详细,确定孔隙度指数m值的公式也越来越精确.对孔隙类型的识别是未来研究孔隙度指数m基础.
The study on porosity exponent m has been an area of abundant interest in logging. Based on the quest and research of log analysts home and abroad on porosity exponent m, this paper summarized some methods. From the porosity exponent m of reservoir only with interparticle pore to that of reservoir with dual porosity ,now the porosity exponent m of reservoir with triple porosity is developed. It can be seen that with the hard situation of exploration,the porosity models are more complicated, and the description of reservoir are more detailed, so the equations to determine porosity exponent rn are more accurate. The basis of studying porosity exponent in the future is identifying pore type.
