| titleOfInvention | Low-temperature instant salt-resistant integrated water-based thickener for fracturing fluid and preparation method thereof |
| abstract | The invention discloses a low-temperature instant salt-resistant integrated water-based thickener for fracturing fluid and a preparation method thereof. Functional monomer, then add acrylamide, acrylic acid and salt-tolerant monomer, salt-resistant hydrophobically associative polyacrylamide prepared by aqueous polymerization method, crushed and mixed with dispersant and dispersion stabilizer, add dispersoid and disperse The auxiliary agent is stirred at a high speed to obtain a low-temperature instant salt-resistant integrated water-based thickener for fracturing fluid. The low-temperature quick-dissolving salt-tolerant integrated water-based thickener for fracturing fluid prepared by the invention has the characteristics of good salt resistance, suspended sand, shear resistance, etc., fast dissolving speed, strong sand suspending ability, and good salt resistance. It can be applied to high salinity water quality solution, can realize on-site continuous mixing and real-time pump injection, meet the requirements of large-displacement construction, low formation pollution and low cost. |
