孤岛油田周缘馆上段河道砂体储层描述

Description on the channel sand body reservoir of upper of Ng of the periphery of Gudao Oilfield

孤岛油田周缘馆上段河道砂体横向变化快,连通性差,缺乏有效的储层描述方法。在高分辨率层序地层格架的基础上,对馆上段的地层进行了细分追踪,运用层控地震复合属性描述的方法,开展储层综合描述与评价,解决了河流相砂体识别困难的问题。在此基础上,创新储层识别"门槛值"概念,结合油层厚度和倾角,建立储层分类标准,取得了良好的勘探开发效果。

The channel sand body reservoir of upper of Ng of the periphery of Gudao Oilfield have a horizontal fastchange, bad connection and lack of effective methods to describe the reservoirs. Based on the high resolution formationframework, the layers of the upper of Ng are divided finely and traced, the comprehensive description andevaluation of the reservoir are made by the layer-controlled seismic multi-attribute description, and the problemthat it is difficult to realize the channel phase sand body is solved. The concept of“threshold value”of reservoir realizationis innovated on the basis of this, the standards of the reservoir classification are set up combined with thethickness and dip of the reservoir, and good effects of exploration and development are obtained.
