GEOSTAR缝洞储层反演技术分析

Analysis of GEOSTAR inversion technique for fractured vuggy reservoir

对于构造隆起幅度大、多期大规模剥蚀、古地质环境复杂、不同目的层储层发育的主控因素差异大的复杂缝洞型碳酸盐岩地质条件,储层预测和识别具有较大的难度。分析了缝洞型储层地震地质特征,并采用GEOSTAR缝洞储层反演技术进行储层识别和预测,应用结果表明,该技术能较好地进行储层空间预测和刻画。

Reservoir prediction and identification is difficult for fractured vuggy carbonate where exist high structure uplift,large scale erosion,complex ancient geological environment and diversified controlling factors of reservoir development in different target layers.The seismic and geological characteristics of fractured vuggy reservoir are analyzed and reservoir identification and prediction are carried out by use of GEOSTAR fractured vuggy reservoir inversion technology.The application results show that this technique can be used to predict and characterize reservoir space.
