摘要
针对彩南油田由于逐年高速开采引发的问题,介绍了为稳产增产而采取的综合治理措施。对采油井采用了隔水、二次压裂、卡堵水工艺、侧钻、化学堵水、油井酸化等措施;对注水井采用了CDG凝胶、聚合物驱、调剖、分注、酸化增注等措施。对这些措施的效果进行了分析和比较表明,CDG凝胶、聚合物驱及侧钻工艺应是今后主要采取的增产措施。
Some troubles resulted from oil production at high speed in Cainan Oilfield have been arisen in recent years. In order to protect stable operation and enhance oil production, some treatment methods were proposed. For oil wells, the methods such as waterproof, water shutoff, secondary fracturing, plugging water flood, side drilling technology, chemical plugging and acid treatment have been used. For water injection wells, some technologies such as CDG gel, polymeric compound driving, profile control and acidization to increase the injected water volume have been adopted. The application results of these treatment methods were analyzed and compared. The technologies of CDG gel, polymeric compound driving and side drilling should be taken as the main treatment methods for improvement of oil production in the future.
