| titleOfInvention | A kind of crude oil viscosity reducer and preparation method thereof |
| abstract | The invention discloses a crude oil viscosity reducer and a preparation method thereof. The crude oil viscosity reducer is composed of a polymer shown in formula I and a polymer shown in formula II, wherein the polymer shown in formula I and the polymer shown in formula II The mass ratio of polymer is 1:(1-30), and the total concentration of described crude oil viscosity reducer is 1g/L-5g/L; In described formula I, R main chain carbon number is 6-30 Alkyl; x is an integer of 5-15; m is an integer of 1-20; in the formula II, y is an integer of 2-10; n is an integer of 10-90. The prepared crude oil viscosity reducer still has a good viscosity reduction effect under high temperature and high salt environment, and has good emulsification and viscosity reduction capabilities for crude oil. |
