【摘要】 针对喇嘛甸油田井震断层匹配矛盾突出、断层表征精度低的问题,运用井震结合断层识别技术,利用井断点与地震信息精细刻画断层。其中,多套井网标定准确地将井断点进行深时转换,与地震断层解释结果进行匹配分析,得出5类断点井震对应关系。对于井震符合好、对应单一的情况,采用井定位置、震控形态的解释方法精细刻画了断距为5m以上断层;对于断裂带部位多个断点对应一个或多个地震响应的情况,采用模式指导、属性约束的解释方法对其进行了精细表征。研究成果指导了喇嘛甸油田北西二区断层边部5口补充井、7口调整井的部署。调整后,平均单井钻遇砂岩厚度为13.8m,有效厚度为10.2 m,增加可采储量2.1×104t。更多还原

【Abstract】 The fault identification in Lamamiao Oilfield is featured by serious match contradiction and low characterization accuracy.Logging-seismic combination fault identification,well breakpoints and seismic data are used to finely characterize faults. Time-depth conversion of well breakpoint is implemented accurately by taking advantage of multiple stets of well pattern calibration,and a matching analysis with seismic fault interpretation result is carried out. Therefore,5 types of corresponding relations between breakpoint and logging and seismic are obtained.更多还原
