| description | The invention belongs to the field of oil field fracturing fluid, and particularly relates to an alcohol-containing fracturing fluid and a preparation method and application thereof. The alcohol-containing fracturing fluid comprises ethanol, ethylene glycol, water, a thickening agent and a cross-linking agent. By adding ethanol, the phenomenon that part of properties become poor due to addition ofethylene glycol into the fracturing fluid can be improved, and along with increasing of the content of ethanol, the viscosity of the ethanol-ethylene glycol-water mixed solvent fracturing fluid is increased, the temperature resistance is good, the sand carrying capacity is enhanced, the viscosity of the gel breaking fluid is reduced, and the content of residues is reduced.
本发明属于油田压裂液领域领域，具体涉及一种含醇压裂液及其制备方法和应用。含醇压裂液包括乙醇、乙二醇、水、稠化剂和交联剂。乙醇的加入可以改善因压裂液加入乙二醇而出现的部分性能变差的现象，随着乙醇含量的升高，乙醇-乙二醇-水混合溶剂压裂液的粘度升高，耐温性变好，携砂能力增强，破胶液粘度降低，残渣含量降低。 |
