摘要
以大情字井油田为例,利用阵列感应测井、时间推移测井以及岩心泥浆侵入试验,说明了钻井泥浆对储层常规测井电阻率值有较大的影响。电阻率测井动态响应模型反演表明,对于水层,淡水泥浆增阻侵入;对于油水同层和油层,淡水泥浆减阻侵入。通过时间推移测井、油基泥浆取芯井、阵列感应测井与常规测井对比统计分析,结合软件反演,得出了不同孔隙结构类型淡水泥浆侵入电阻率校正值。
Taking Daqingzijing oilfield as an example,the effect of the drilling mud on resistivity values of the conventional logging was analyzed by using the array induction logging,time-lapse logging and core mud invasion tests.The dynamic response model inversion of the resistivity logging showed that the increased resistance invasion of the fresh water mud occurred in water layers and the decreased resistance invasion of the fresh water mud occurred in oil-water layers and oil layers.The corrected resistivity value of the fresh water mud invasion for different pore structures were given through comparing the time-lapse logging,the oil-base coring wells and the array induction logging with the conventional logging and combining with software inversion.
