摘要
苏里格气田苏54区块位于鄂尔多斯盆地西北部,前期勘探资料表明区块地质条件、气水关系异常复杂,因此开展储层综合评价对于目标区块的开发非常重要。通过对构造特征、沉积相、储层物性特征进行研究,分析了砂体展布及气水分布规律,确定了有效储集砂体的特征、类型以及主控因素,建立了储层综合评价的分类标准,并根据该标准对目标区的主力产层进行了分类评价。预测认为在目标区的东部、中部、西北部和西南部存在4个气藏富集区域,并根据研究成果部署下一年的产能建设任务,取得了良好的实施效果。该项研究成果为指导苏里格气田规模开发提供了技术支持,同时也为我国同类气田开展储层综合评价工作提供一定的借鉴。
Su54 block of Sulige gasfield is situated in northwestern Ordos Basin. Previous exploration shows that it is featured by the extremely complicated geological condition and gas-water relation. Therefore, reservoir comprehensive evaluation is important. Based on structural characteristics, sedimentary facies and reservoir physical properties, the law of sandbody and gaswater distribution was analyzed, the characteristics, types and main controlling factors of effective reservoir sandbody were determined, the standard to classify reservoir comprehensive evaluation was established and under this standard, the main production layer was classified and evaluated.Results indicate that there are 4 gas accumulation areas individually in the eastern, central, northwestern and southwestern target zone. Better result has been achieved in productivity construction.This research provides a technical support for large-scale development of Sulige gasfield, and can be guidance for reservoir comprehensive evaluation of other similar gasfields.
