| Abstract: | The composite reducer was composited by a terpolymer (acrylic ester, maleic anhydride and styrene) and nonionic surfactant in the ratio. The influence factors for reducing pour point and viscosity, the ratio of each substance in terpolymer, the ratio of terpolymer and nonionic surfactant, were discussed. The freezing point of the oil dropped 14 ℃ and the degree of viscosity dropped 63.6% under the temperature 50 ℃, rate of shear 100 s -1 , viscosity of the crude oil 5500 MPa·s, adding quantity 0.4%. |
