摘要
针对吴仓堡油田长9储层岩性复杂、物性变化较大及油层有效厚度下限难以确定等实际情况,在对储层岩性进行了识别之后,建立了该地区储层参数测井精细解释模型,采用孔隙度～电阻率交会法确定了油层的有效厚度起算标准,并利用含油产状法、压汞法及经验统计法对油层物性下限进行了印证,进而弄清了在现有经济技术条件下研究工区的物性动用下限。基于本文所建立的有效厚度起算标准,对该工区内266口井进行了数字处理和综合解释。解释结果与试油试采对比表明,测井解释符合率较高,能够满足储量参数计算和开发方案制定的要求。
According to the actual conditions of Chang 9 reservoir in Wucangbao oilfield,such as complex lithology,large variation of physical property and hard determination of the lower limit of effective thickness of oil layers,the precise interpretation model of reservoir parameter in the area is established after identifying reservoir lithology.Porosity-resistivity intersection method is used to determine the effective thickness standard of reservoirs,and oil-bearing occurrence method,mercury intrusion and empirical statistics are used to corroborate the reservoir physical lower limit,then to find out physical limit in the research area under present economic and technical conditions.266 wells in the area were processed and interpreted base on the standard.Comparison of interpretation result with oil testing indicates that the interpretation coincidence rate is high and it can meet the need of calculating reserves parameter and working out development programs.
