| titleOfInvention | A kind of shale gas acid fracturing drag reducer and preparation method thereof |
| abstract | The invention discloses a kind of shale gas acid fracturing drag reducer and preparation method thereof.Monomeric acrylic and 2 acrylamide 2 methyl propane sulfonic acids are mixed by the present invention, soluble in water, are subsequently adding acrylamide, finally add disodium ethylene diamine tetraacetate and be configured to aqueous phase；By compound surfactant and base oil mixed dissolution, form oil phase；Then oil phase and aqueous phase are carried out inverse emulsion polymerization, prepare shale gas acid fracturing drag reducer.This drag reducer introduces a large amount of acid-resisting monomer, greatly improves the capacity antacid of drag reducer；Drag reducer outward appearance is milky emulsion, and stability is high, does not fires, the most quick-fried, transports and stores safety；This drag reducer dissolves soon in water, will not form flake, meet the requirement of the continuous mixture of shale gas acid fracturing；Mass fraction is the dreg reducer solution of 0.2%, and its resistance-reducing yield just can reach more than 70%. |
