Abstract: Multistage fracturing of horizontal well is a good explored mode for unconventional oil and gas resources. In this mode, continuous mix is required, and fracturing liquid is required to dissolve and disperse in a short time in order to fit application demand.The basic physical property, dispersibility and swelling property of an instant guar gum are studied, which is compared with another used guar gum in work site. The results showed that the instant guar gum was characteristic of favorable dispersibility and swellability and met the requirements of operation. It has been used in Xinjiang oil field successfully.

Key words: Instant guar gum,    ,  Senior guar gum,    ,  Dispersibility,    ,  Swellability

摘要： 水平井多级压裂是对非常规油气藏资源的一种良好的开发模式。这种开发模式需要的压裂现场工 艺是连续混配, 要求压裂液体能够在短时间分散溶解好, 原液黏度要在短时间达到施工要求。经过实验室评价, 对 一种速溶胍胶的基本物性、 分散性能以及溶胀性能进行了评价, 并与现场常规使用的一级胍胶的性质进行对比。实 验表明, 这种速溶胍胶在分散性和溶胀性上具有良好的性能, 能够满足现场施工要求。新疆油田成功应用该速溶胍 胶进行施工。
