Abstract: 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.

摘要： 从众多植物胶压裂液体系中选取一级胍胶、香豆子胶以及苦苈胶进行实验室评价,通过对胶粉组成、
原液黏度、耐温耐剪切性能等方面评价,得到几种植物胶压裂液体系的优缺点,结果表明:三种植物胶在组成上具有
相似性,都是多羟基化合物,在质量分数为0.5%时,苦苈胶黏度最大为91.6mPa·s,三种植物胶的耐温耐剪切性均
能满足现场施工要求,一级胍胶的残渣质量浓度最小,为23.3mg/L。
