摘要
经过长期注水开采油田进入高含水期,油层内油、气、水交错渗流,剩余油的挖潜难度加大。高含水剩余油分布研究主要从剩余油分布研究方法、剩余油分布特征、剩余油分布控制因素三方面进行。总结目前剩余油分布及挖潜技术研究的国内外研究状况和最新进展,提出周期注水、降压开采等剩余油挖潜措施。
Oilfield falls into the stage of high water-cut after a long-term of exploitation. Owing to the mixing flow of oil, gas and water in the oil layer, the exploiting of the remaining oil becomes increasingly difficult. The study on the distribution of the remaining oil is consisted of three aspects： the research methodology of the remaining oil; the feature of the remaining oil＇s distribution and the factors influencing its distribution. In connection with the analysis and to solve the existing problems, some improved potential tapping techniques of the remaining oil have been put forward, such as circulatory water flooding and decompressional exploitation.
