阳离子胍胶的研制及其在油田中应用的室内试验

Development of Cationic Guar Gum and Laboratory Experiment of Oilfield Application

研制出了阳离子胍胶 ,并分析了其特性。在室内试验了阳离子胍胶作为增粘剂在钻井液、完井液、压裂液等方面的应用 ,并筛选出符合各类技术指标的合理配方。说明阳离子胍胶在油田有着广泛的用途。

A cationic guar gum is developed, its property is analyzed. The cationic guar gum used as a viscosifier in drilling, fracturing and completion fluids is tested in laboratory, rational formula in consistent with each technique is chosen .It is indicated that the cationic guar gum would be widely used in oilfields.
