摘要

针对元坝气田长兴组碳酸盐岩储层孔隙结构复杂、非均质性强的特点,通过测试法、实验分析法、经验统计法等多种方法,对长兴组储层的有效孔隙度下限进行了综合研究,确定了元坝气田长兴组气藏有效孔隙度下限为2.0%,完成了元坝气田长兴组气藏第一期探明储量计算.

Abstract

The carbonate gas reservoirs of the Changxing Formation in the Yuanba Gas Field are characterized by complex pore structure and strong heterogeneity.A comprehensive study has been taken through test,experimental analysis and experience statistical method for the lower limit of effective porosity of the Changxing Formation.The research result shows that the lower limit of effective porosity is 2.0%.The first stage of proven reserves has been calculated on this basis.
