| titleOfInvention | A kind of preparation method of multi-functional slickwater fracturing fluid drag reducer drag reducer |
| abstract | The present invention relates to a kind of preparation methods of multi-functional slickwater fracturing fluid drag reducer drag reducer, it is reacted using inverse emulsion polymerization, two kinds of nonionic emulsifier are compounded to form to the emulsifier of compounding, the emulsifier of compounding is dissolved in oil medium by mass fraction 0.3%, 1~2h is stirred under nitrogen protection, add 0.3% hydrophobic monomer of mass fraction, then the chelating agent of mass fraction 0.3~0.5% is added, with the monomer solution of acrylamide and 2- acrylamide-2-methyl propane sulfonic, it starts to warm up, when temperature rises to 52~57 DEG C, oil-soluble initiator and water soluble starter is added portionwise, 8~10h is kept the temperature after initiator adds, finally obtain a kind of stable water-in-oil type polymer emulsion.The present invention utilizes inverse emulsion polymerization method, by introducing special functional group's substance and emulsifier, develop it is a kind of with drag reduction, help the slippery water drag reducer of row function, not only reduce slippery water cost, more importantly shorten liquid preparation time, simplify and match liquid program, construction efficiency is greatly improved. |
