摘要:

对埋藏浅、储层温度低的油气藏进行压裂改造，需要解决压裂液低温破胶、快速返排和伤害问题。本文介绍了一种有机硼交联胍胶压裂液体系，描述了该体系的破胶、返排和低伤害性能，介绍了该压裂液体系在川西白马一松华地区成功进行的4井次低渗浅层气井现场试验，取得了良好的应用效果。

Abstract:

The primal problem in low temperature and shallow gas reservoirs is to overcome the break,the flowing back,and the damage of the fracturing fluids.This article introduces an organic-borate crosslinked guanidine gum fracturing fluids and theirs performance
