三维地震资料的储层预测──以开鲁盆地陆西凹陷包1块为例

Seismic Reservoir Prediction of Bao - 1 Block in Louxi Depression, Kailu Basin

以内蒙古开鲁盆地陆西凹陷包１块油藏为例，提出了以地震资料为核心，综合应用地质、测井和钻井资料进行储层预测的基本方法．在对三维地震资料进行精细构造解释的基础上，由速度谱资料求取了地震层速度，进而顶测了九佛堂组上段的砂泥岩百分比的横向变化和地层压力；采用协克里金方法，综合地震、测井及岩心资料预测了储层孔隙度；应用地震模式识别技术预测了包１块含油气范围。

The reservoir prediction of the Bao - 1 block, in the west of the Luxi depression, Kailu basin has been completed on seismic data. On the basis of exact interpretation of 3D seismic data, the interval velocities are computed, the sand - shale percentage and the formation pressure are predicted. Using cokriging method, the reservoir porosity is estimated. The oil and gas range of Bao - 1 block is also predicted by using the seismic pattern recognition.
