【摘要】 测井资料在横向上连续性差,在断层解释方面存在着无法组合孤立断点、多解性断点和井间小断层等缺陷。与测井解释断层相比,地震资料在横向上精度高,具有断层空间组合方面的优势。但地震资料属于时间域,不能被油田开发直接应用。井震联合建模通过时深转化技术将深度域上的测井数据转换到时间域上,并通过方差体分析、蚂蚁追踪、断点归位等技术综合解释断层的空间形态。井震联合技术应用于大庆油田某区块的地质构造精细解释,成功地解决了孤立断点、多解性断点、井间小断层无法解释等问题,实现了测井资料与地震资料的优势互补。更多还原

【Abstract】 Logging data were poorly continual in the horizontal direction.In fault interpretation,there existed many isolated breakpoints,multi-solution breakpoints,small cross-hole faults and some other defects which could not be accurately interpreted on simply logging data.Compared with the logging interpreted fault zones,seismic data were more accurate in the horizontal direction and had advantage of spatial combination of fault zones.However,seismic data for its time domain,it could not be directly used for oilfield development.For the combined modeling of logging and seism,logging data in depth domain were able to be transformed into time domain.Variance volume interpretation,ant tracking,breakpoint homing and other technologies were integrated for interpreting fault in this progress.This technology is used successfully to solve the problems that the isolated breakpoints,multi-solution breakpoints and small interwell faults can not explain and achieve a highly acceptable complementation of logging data and seismic data in a block of Daqing Oilfield.更多还原
