| titleOfInvention | Hydrophobic association polymer and synthesis process thereof |
| abstract | The invention discloses a hydrophobic association polymer and a synthesis process, which are characterized by comprising, by weight, 360 parts of pure water 320-one, 0.25-0.75 part of disodium ethylene diamine tetraacetate (Edta-2Na), 25-35 parts of baking soda, 18-22 parts of acrylic acid, 12-18 parts of potassium chloride, 95-105 parts of acrylamide, 15-20 parts of urea and 25-30 parts of monomers, wherein the Edta-2Na sand carrying capacity is less than 20% after 2 +/-0.1 h sedimentation, and the dry powder has the viscosity of 0.25% and 21-27%. Compared with the prior art, the invention has the advantages of simple operation, low production cost, stable product quality and extremely low influence on environmental pollution. Meanwhile, the invention has the advantages of wide raw material source, simple production operation, low cost and small influence on the environment; the product has the advantages of stable quality, good solubility, temperature resistance, salt tolerance, shear resistance, high viscosity and the like, and is suitable for medium and low temperature oil and gas reservoir fracturing construction and tertiary oil recovery. |
