| titleOfInvention | A nano-enhanced supramolecular cleaning fracturing fluid and its preparation method |
| abstract | The invention discloses a nano-enhanced supramolecular cleaning fracturing fluid and a preparation method thereof. The nano-enhanced supramolecular cleaning fracturing fluid is composed of nano-hydrophobic association polymer, anionic surfactant, viscosifying inducer, gel breaker and water according to (0.2～1):(0.2～3):(0.5～2) :(0.01～0.1):100 mass ratio compounded; wherein, the above-mentioned nano-hydrophobic association polymer is obtained by reacting surface amino-modified nano-silica and hydrophobic-associated partially hydrolyzed polyacrylamide. In the present invention, the nanometer-enhanced supramolecular cleaning fracturing fluid is prepared by using the nano-hydrophobic association polymer formed by the reaction of surface amino-modified nano-silica and hydrophobic association partially hydrolyzed polyacrylamide as a raw material, which can improve the performance of the fracturing fluid at high temperature. Viscosity and suspended sand performance, and is beneficial to reduce the residue content; at the same time, the present invention can be formulated as seawater-based or freshwater-based clean fracturing fluid. |
