【摘要】 针对胜坨油田坨71地区断裂系统复杂性,采用了三维地震资料再处理技术,并结合相干及曲率分析法,精确刻画了断裂系统;针对砂砾岩储层多期混杂沉积、横向变化快、应用常规测井曲线进行对比难度大、扇体储层展布规律不清的难点,综合应用小波变换、聚类分析和INPEFA曲线重构技术实现了地层的精细对比划分,明确了储层展布规律。更多还原

【Abstract】 In view of the fracture system complexity of Tuo 71 area in Shengtuo oilfield,3D seismic data reprocessing was adopted.In combination with curvature analysis,the fracture system has been accurately depicted.In view of the glutenite reservoir characteristics,such as multiphase mixed sedimentation and quick horizontal change,by use of the conventional logging curve,the comparison difficulty is big and the fan reservoir distribution regularity can not be made clear.With integrated application of wavelet transform,clustering analysis and the formation of INPEFA curve reconstruction technology,the fine stratigraphic correlation and reservoir distribution regularity have been achieved and made clear.更多还原
