摘要
基于岩心观察、铸体薄片、压汞分析和常规物性分析资料,对DM块储层微观孔隙结构和物性特征进行分析研究。结果表明:砂砾岩体储集空间类型主要为粒间孔和溶蚀孔,储层孔隙度平均9.8%,渗透率最平均0.5m D,属于低孔-特低渗储层。
Based on core observation, cast sheet, Mercury pressure analysis and conventional material analysis data, the microstructure and physical characteristics of the DM reservoir were analyzed and studied. The results showed that the reservoir space of gravel rock was mainly intergranular and dissolution, the average porosity of the reservoir was 9.8 %, and the average permeability was 0.5 mD.
