ABSTRACT: In oilfield fracturing construction, to solve the technical problems such
as poor dissolution effect and long dissolution time of polymer drag reducer
powder, the rheological regulator, phase transfer agent, organic solvent, and
drag reducer powder were compounded to prepare a drag reducer emulsion that was
soluble in water. The stability of the drag reducer emulsion was observed at
room temperature for 90 days. The effects of the rheological regulator, phase
transfer agent, and organic solvent on the stability and solubility of the drag
reducer emulsion were studied. The dissolution time, dissolution effect,
viscosity of the aqueous solution, and drag reduction performance of the drag
reducer emulsion were evaluated. The results show the stability rate of the
drag reducer emulsion prepared by MOST-1 rheological regulator, BHJ-8 and BHJ-6
compound phase inversion agent, ethylene glycol ether and 120 - 140 mesh powder
can reach 97% at room temperature for 90 days. Compared with the drag reducer
powder, when the aqueous solution concentration is 0.1%, the dissolution time
is only 28 s, the viscosity can be increased by 30%, and the drag reduction
rate can be increased by up to 8%.
