三维地震精细解释技术在饶阳凹陷马西地区的应用

Application of 3-D fine seismic interpretation technique in Maxi area of Raoyang sag.

渤海湾盆地冀中拗陷饶阳凹陷北部马西地区是潜山、地层岩性和构造等复式油气藏聚集区。本文基于该区三块三维地震资料,分析了进行精细解释的难点,有针对性地采用了采集—处理—解释一体化运作模式、叠前时间偏移处理技术、精细层位标定技术、变速时深转换技术、复杂断块精细解释技术、平衡剖面技术、高精度层序地层技术、地震属性分析技术、三维可视化技术、储层反演技术及低幅度小面积深潜山识别技术等,完成了对该区三维地震资料的精细解释,取得了一系列的成果,应用效果良好。

The Maxi area of Raoyang sag in Jizhong depression,Bohai basin,is buried hill,stratigraphic-lithologic and structural composite oil/gas accumulated zone.Based on three blocks of 3-D seismic data in the area,the paper analyzed the difficulties of fine interpretation,purposefully used acquisition-processing-interpretation integrative technique,prestack time migration processing technique,finely strata-calibrating technique,variable-velocity time-depth conversion technique,fine interpretation of complex fault ...
