摘要
复合离子调剖剂已在大庆油田得到广泛应用,并取得了一定的开发效果。但针对复合离子调剖剂的微观结构、在多孔介质的流动规律研究很少,无法了解复合离子调剖剂在多孔介质中的成胶情况,而复合离子调剖剂的成胶性能是与其效果息息相关。因此有必要开展复合离子调剖剂动静态性能综合评价。文章在室内对复合离子调剖剂进行了长管流动测定和静态及短岩心对比实验,首次提出并在室内进行了多孔介质的流动能力实验,并与常规静态实验结果进行了对比分析。实验表明复合离子调剖剂在多孔介质条件下成胶性能变差,不仅为客观优选评价凝胶类调剖剂提供了保障,而且也为优选其它凝胶类调剖剂提出了技术决策数据。
In Daqing Oilfield,compound-ion profile flooding technology is used wildly,and has obtained the better application results. The paper analyzed the static and dynamic property of compound-ion profile control agent,carried out the check experiment of compound-ion profile control agent in long sand-pack flowage and static determination and short core,put forward and carried out the flow capacity experiment of compound-ion profile control agent in porous medium in lab. Compared with conventional static experiment results,the gelling performance of compound-ion profile control agent in porous medium becomes poor. The experimental results provided a new method for optimizing gel profile control agent.
