摘要:

CT9-6是一种用于压裂施工作业的有机硼交联剂,以其为主剂构成了缓交联体系.通过调节体系各组分的加量,可实现20 s～15 min的缓交联时间;用其交联羟丙基胍胶(HPG)形成的冻胶耐温、抗剪、易破胶、滤失伤害小.该交联剂在四川油气田进行数井次的现场试验表明该剂悬浮性能良好,破胶彻底,增产效果明显.

Abstract:

On the basis of organic borate cross-linker CT9-6, a new delayed cross-linking fracturing fluid is developed. The cross-linking time can be adjusted conveniently between 20s~15min. The gel by hydroxypropyl guarfum with CT9-6 have the good performance as g
