【摘要】 针对塔里木DH油田超深井、高温、低渗透储层和注水井特点,提出了对压裂液性能的要求,优选了与超深井压裂相适应的有机硼交联改性瓜尔胶压裂液体系的配方和添加剂。介绍了塔里木高温深井压裂液的应用情况,分析讨论了该压裂液控制延迟交联,降低摩阻,优化配方,改善流变性能,以及低伤害特性等。现场应用表明,有机硼交联改性瓜尔胶压裂液具有低摩阻、流变性能好、携砂能力强、破胶彻底、低伤害等特点,满足了井深5850m以上超深井压裂施工的要求。更多还原

【Abstract】 A novel fracturing fluid system, boron crosslinked fracturing fluid system was introduced for using in the ultradeep and water injection wells with high temperature and low permeability in Tarim. The composition and properties of the system are described in detail. Tests indicated that the system possess the advantages of low friction, easy pumpability, good cutting transportation and low formation damage, etc, thus could be successfully used in wells over 5850 m.更多还原
