摘　　要：储集层的物性参数是评价储集层的重要基础数据,对储集层评价的准确程度有较大影响,文章统计分析结果表明砂岩储集层岩石密度与储集层主要物性参数之间有良好的相关性。以区域统计规律为基础,建立了东濮凹陷砂岩储集层体积密度与孔隙度和渗透率的关系方程。介绍了录井施工现场应用岩屑样品体积置换法、泥岩密度计法两种常规检测方法,能较准确的获取砂岩储集层的体积密度,反演计算孔隙度和渗透率数据,合理评价储集层物性参数,为准确评价储集层提供了可信度高的重要基础数据,从而弥补了录井现场物性参数获取不足的缺陷,在随钻评价油气储集层过程中有一定的实用价值。The physical parameters of the reservoir are the important and basic data to evaluate reservoirs, they affect the accuracy of the reservoir evaluation heavily. The statistic and analyzing results of the paper showed that the good correlations were existed between rock density of the sandstone reservoir and the main physical parameters. On the basis of the area statistic regulation, the author established the relationship formula for volume density of the standstone reservoir and porosity and permeability in Dongpu Depression. By using the methods of cutting sample volume displacement and clay density detection on mud logging site, the paper introduced that the volume density of the sandstone reservoir can be obtained accurately, porosity and permeability data can be calculated inversely, and physical parameters can be evaluated reasonably. It provided the important and basic data with high credibility for accurately evaluating reservoirs, made up the defect of being lack of obtaining physical parameters at logging site, the methods have certain practical value during oil and gas reservoir evaluation while drilling.
