Select the level of guar gum, from the system of many plant gum fracturing fluid in sweet bean gum and bitter drabanemerosa hebecarpa glue for laboratory evaluation, based on the composition of powder, liquid viscosity, shear performance and evaluation of Nevinne, has advantages and disadvantages of several plant gum fracturing fluid system, the results show that: the three kinds of plant gum has the similarity in composition, are polyhydroxy compounds, at the concentration of 0.5%, bitter drabanemerosa hebecarpa viscosity maximum is 91.6 mPa·s, Nevinne shearing of three kinds of plant gum, can meet the requirements of construction site, a guar gum residue mass concentration is 23.3 mg/L minimum.
