| Abstract: | This article mainly introduces the way of laboratory preparation of hydroxypropyl guar gum used in oilfields. The effects of content of guar gum on the content of water - insoluble substance and the effects of crosslinker on the viscosity of fracturing fluid were examined. The temperature - resistance and salinity tolerance of hydroxypropyl guar gum were also evaluated. The result showed that the content of water -insoluble substance in hydroxylpropyl guar gum was less than half the content in original guar gum. Addition of crosslinker could help increase the viscosity of fracturing fluid. The temperature - resistance of hydroxylpropyl guar gum was not so ideal, but the salinity tolerance was obviously better than that of original guar gum fracturing fluid. |
