摘要
八面河西区沙四段滩坝砂体岩性组合复杂、横向变化快、储层精细刻画难度大。在现有的资料和技术状况下,测井上运用沃尔什反演法提高测井曲线纵向分辨率,地质上开展由砂组到小层再到砂体的逐级控制精细储层对比描述井间储层变化,地震上通过相控非线性随机反演技术精细刻画储层的平面展布,油藏上利用生产动态资料辨别砂体连通性进而验证和修正储层展布边界,小层圈闭识别精度大大提高。
There are the complex lithological combination,fast lateral change and difficulty to make refined reservoir description in the beach bar sand body of the Sha 4 member of the western Bamianhe area.With the existing data and technical conditions,the vertical resolution of logs is improved by using Walsh inversion technique;the refined reservoir correlation between sands and sublayers is used to make description of inter-well reservoir changes in a gradual control;the phase-controlled nonlinear random inversion technique is used to conduct a refined characterization of plane distribution of reservoirs;the producing performance data are used to identify sand connectivity and to verify and modify a reservoir distribution boundary.
