通过对研究区取芯井的分析化验资料进行储层岩石学特征统计分析及对比,东泉-西泉地区都以岩屑砂岩为主,其次为长石岩屑砂岩。运用扫描电镜、铸体薄片、压汞等技术手段对储层进行精细微观结构分析,包括孔隙类型、孔隙结构等,分别对比储层物性特征及其主要影响因素,西泉地区孔隙度、渗透率较优于东泉地区,为相对优质储层。 Through statistical analysis and comparison of the reservoir petrology characteristics of the analytical laboratory data of the coring wells in the study area, mainly composed of lithic sandstone and later feldspar lithic sandstone in the Dongquan-Xichu area. The microstructure of the reservoir is analyzed by means of scanning electron microscope, cast thin slice and mercury intrusion, etc., including pore type and pore structure. Comparing the physical property of reservoir and its main influencing factors, the porosity and permeability of XQI Better than Dongquan area, as a relatively high-quality reservoir.
