| description | The invention discloses a fracturing fluid and a preparation method thereof, and belongs to the field of oil field chemistry. The fracturing fluid is prepared from the following components in percentage by mass: 0.15-0.4% of a crosslinking monomer with a molecular weight of 200 thousands to 500 thousands, 0.1-0.8% of a tackifier with a molecular weight of 500-2000, 0.01-0.05% of an anti-flocculating agent, 0.1-0.8% of a surfactant, 0.3-0.8% of a crosslinking agent, 0.1-2% of a gel breaker, 0.01-0.2% of a pH value regulator and the balance of water, wherein the tackifier is polyacrylamide, andthe surfactant is an amino acid surfactant. The fracturing fluid has good fluidity and good sand carrying and crack making functions, has no damage to a reservoir after gel breaking, and can be conveniently pumped to the reservoir.
本发明公开了一种压裂液及其制备方法，属于油田化学领域。该压裂液通过以下质量百分比的各组分制备得到：分子量为20万～50万的交联单体0.15％～0.4％、分子量为500～2000的增粘剂0.1％～0.8％、防絮凝剂0.01％～0.05％、表面活性剂0.1％～0.8％、交联剂0.3％～0.8％、破胶剂0.1％～2％、pH值调节剂0.01％～0.2％、余量为水；增粘剂为聚丙烯酰胺；表面活性 |
