摘要
根据克拉玛依油层情况,提出了碱-聚合物稠化水驱油体系的配方:0.05%HPAM+0.05%六偏磷酸钠+0.1%氢氧化钠,讨论了体系中各组分的功用和碱-聚合物驱提高采收率的机理。研究表明,该体系能大幅度提高原油采收率,特别适合于原油粘度高、岩石表面亲油的油层。
An alkaline-polymer flooding system is suggested for field tests in Karamai Oil Field,It contains 0.05% partially hydrolyzed polyacrylamide,0.05% sodium metaphosphate and 0.1% sodium hydoxide in the formation water in-situ.The functions of every ingredient in the system and the mechanizms of oil displacement are experimentally studied through in-tube and flat core tests and discussed in this paper.
