摘要: 聚丙烯酰胺柠檬酸铝交联聚合物溶液(LPS)深部调驱先导试验结果表明,低浓度的交联聚合物溶液可以堵塞聚合物驱、水驱形成的水通道,提高注水井的注入压力,起到深部调剖、液流改向的作用,使驱替液进入聚合物驱、水驱未波及的含油层(层内或层间),增加生产井的产油量,降低含水率,进一步提高聚合物驱油藏的采收率。LPS深部调驱技术可作为聚合物驱的接替技术用于聚合物驱后油田的开发.

Abstract: An experiment of in-depth profile control using a linked polymer solution (LPS) of polyacrylamide (HPAM)-aluminum citrate (AICit)was conducted in Shengli Oilfield.The result shows that the linked polymer solution with a low concentration of polymer is able to plug the water channel formed by polymer flooding or water flooding.Therefore,the injecting pressure of injection well increased and the driving fluid can be easily diverted into oil-bearing reservoir.The technology taking linked polymer solution as in-depth profile control agent can increase the oil production and decrease the water cut of producing well.The technology can be used for oil recovery of the reservoir after polymer flooding.

Key words: linked polymer solution, in-profile fluid diversion, enhanced oil recovery, experiment
