摘要
介绍了聚合物冻胶体系延迟交联作用机理,并针对深部调剖技术要求,研制出一种高效延迟交联剂配方,使聚丙烯酰胺堵剂冻胶的成胶时间在3～6d。该堵剂具有可泵性好,交联时间可控,成胶后强度高、对人造岩心封堵率大等特点,可用于深部调剖。
This paper describes the mechanism of suspend crosslinking acting in polymer jell system. Based on the requirement of deep profile control technology, a kind of high efficiency formula of suspend crosslinking has been developed, and the form ing time of polypropylene amide bridging particle jell is 3 - 6 days. The bridging particle has the characteristic of good pumping; high crosslinking robustness and high plugging rate for artificial core, and it can be used in deep profile control.
