| titleOfInvention | Reducing thick oil viscosity helps row composition, viscosity reduction cleanup additive, preparation method and application |
| abstract | The invention discloses a kind of reducing thick oil viscosities to help row composition, viscosity reduction cleanup additive, preparation method and application, belongs to technical field of petroleum extraction.The viscosity reduction helps row's composition to be grouped as by the group of following mass fraction: 0.1~2 part of fluorocarbon surfactant, 0.5~1 part of hc-surfactant, 0.25~1 part of auxiliary agent, 0.05~0.3 part of cleanup additive.Wherein, fluorocarbon surfactant is selected from one of FC-01, FC-02, FC-04-1, FC-06, FC-08, FC-11 or a variety of；Hc-surfactant is selected from one of α-sodium olefin sulfonate, SYHSY, SDBS, YN or a variety of；Cleanup additive is selected from one of F370, F633, SH6 or a variety of.The viscosity reduction helps row's composition to have lower surface and interface tension, and the dynamic viscosity of viscous crude can be effectively reduced, and improves surface wetting, improves water recovery rate. |
