摘要

开发中后期油田对储层参数精细二次解释要求高,直接影响老油田剩余油挖潜策略的制定。以L油田为研究对象,充分利用录井、岩心、取芯井分析化验和试油试采等资料,建立了更为科学合理的测井二次解释新模型,消除了测井系列多、标准多和解释时间跨度长等带来的误差,储层参数解释精度提高了8%;完成了71口井的测井重解释以及31个小层的孔隙度及渗透率等值线图绘制,提高了储层参数在平面和纵向上的空间分布预测准确度;结合储层构造、沉积特征,通过相邻井的横向和纵向比较,提高了解释结果与实际地质情况匹配度,为老油田剩余油有效深度挖潜提供更为有利的地质依据。
        Secondary interpretation of reservoir parameters of fine logging during middle and late development of oil fields is of great importance to exploitation ofproductive potential of an old oilfield. This study establishes a new and more reliablesecondary interpretation model of fine logging based on logging data, core analyses and producing test. The same new model is applied to the L oilfield which eliminates errors from long time span and varied logging series and standards and enhances precision of reservoir parameter interpretation by 8%. Secondary interpretation of fine logging data for 71 drill wells enhancesaccuracy of spatial distribution prediction, providing scientific basis forexploiting the potential of old oil fields.
