摘　　要：对玉米淀粉经化学和物理变性制得变性淀粉。将该变性淀粉与少量植物胶XDF复配制成压裂液稠化剂。并对该稠化剂的理化性能、用量、复配比例以及压裂液的配方、性能和影响凝胶的因素进行了研究。结果表明:用该稠化剂配成的压裂液粘度高、流变性好、摩擦阻力小、易破胶、低残渣、低伤害,是一种适用于80℃以下低温的优良压裂液。Modified corn starch mixed with vegetable gum XDF used for drilling of oil wells is described in this paper.The physical and chemical properise,usage and mixing ratio of this modified starch are also given.Meanwhile,the ingredients of drilling mud and the factors affecting the colloid are studied.This kind of mixture has the characteristics of high viscosity,sufficient fluidity,low friction resistance and low residue,and can give the best performance under 80℃.
