| 摘 要： | 针对南泥湾采油厂压裂施工后返排液多、处理费用高,研究了羟丙基胍胶压裂液重复利用技术.首先,以羟丙基胍胶为稠化剂,硼砂为交联剂,缓释型SS-1为破胶剂制备可重复利用的压裂液基液.然后在40℃条件下,优化重复利用时破胶液与基液的混合比例,以及向混合液中加入交联剂、破胶剂和交联促进剂的量,满足现场施工60 s内交联、3 h后破胶的要求.通过室内实验确定了重复利用压裂液体系最佳配方:破胶液与基液混合体积比为1∶3,加入交联剂硼砂质量分数0.035%～0.045%,缓释型破胶剂SS-1质量分数0.25%～0.35%,交联促进剂质量分数0.03%～0.06%.性能评价结果表明,该压裂液体系具有良好的流变性和抗剪切性,滤失量小,破胶彻底和残渣低等优良性能,实现了压裂液的重复利用.

| Abstract: | In order to solve the resource waste and the environment pollution of a great deal of flow-back fracturing fluid in Naniwan oilfield,a reusing technique of hydroxypropyl guanidine gum fracturing fluid was developed.Firstly,the recoverable fracturing fluid was prepared using hydroxypropyl guanidine gum as thickeners,borax as cross-linking agent and a slowly-releasing SS-1 as gel breaker.Then,the mixing volume ratio of gel breaked fluid to basic fluid(the recoverable fracturing fluid),and the adding amount of... |
