At present, the thickening agent used in fracturing of oilfields at home and abroad is mainly hydroxypropyl guar gum. Guar gum is endosperm derived from the annual herb guaer bean. Our company directly imports guar gum beans from abroad to grind, separate and produce guar gum powder. Chemical modification of guar gum powder is carried out to produce hydroxypropyl guar gum powder to increase water solubility, reduce water insoluble matter, and improve the thermal stability performance and shear resistance of fracturing fluid. The hydroxypropyl guar gum produced by our company is affordable, the water insoluble matter is low, the thickening capacity is strong, and the temperature resistance and shear resistance of the fracturing liquid are good.
