Nitrogen foam profile control in waterflooding heavy oil reservoir
辽河油田稠油油藏大部分采取注水开发方式生产,现已进入高含水开发阶段.随着弱凝胶调剖堵水施工轮次的增加,开发效果呈递减趋势.为改善油田注水开发效果和提高采收率,进行了氮气泡沫调驱技术研究.室内对比了3种起泡剂的表面张力和半衰期,研究了交替段塞的大小、气液比及段塞组合对泡沫体系的阻力特性的影响.室内实验结果表明,实施泡沫调驱后,采收率提高9%.在海外河油田的2口注水井进行了矿场试验,见到了明显的增油降水效果.
Water-flooding development is used for the production of most heavy oil reservoirs in Liaohe Oilfield, most of the reservoirs have been at the stage of high water cut. With the increase of number of weak gel profile control water plugging, the development decreases progressively. To improve the waterflooding development effect and enhance oil recovery in the oilfield, study is conducted on the nitrogen foam profile control technology. Through indoor ex…查看全部>>
