综合测试技术在剩余油评价和挖潜中的应用

Application of Integrated Testing Technology to Remaining Oil Evaluation and Tapping Potential

围绕注水开发油藏剩余油分析和挖潜需要,在GD油田注水开发区块建立初始地质模型;通过采用水流模拟方法,结合运用多井综合测试和生产数据,建立精细的动态分析模型,确定油水井连通性和油藏内剩余油分布状况,描述优势渗流通道分布。针对储层物性、剩余油分布特点和目前井网条件下的注采对应关系,提出挖潜方案,在增加可采储量、提高采收率等方面取得理想的地质应用效果。

According to the waterflooding reservoir remaining oil analysis and exploration, the initial geologic model is established for the water injection development blocks of GD oilfield.By adopting the method of water flow simulation combined with multi-well integrated testing and production data, the fine dynamic analysis model is made to determine the connectivity of oil and water wells and the distribution of remaining oil in reservoirs, and to describe the distribution of dominant seepage channels.In view of the reservoir physical properties, the remaining oil distribution characteristics and the corresponding injection-production relationships under the well pattern condition at present, the potential tapping scheme is put forward, and the ideal geological application effect is achieved in the aspects of increasing recoverable reserves and improving oil recovery.
