| titleOfInvention | Self-demulsification type temperature-resistant viscosity reducer for cold recovery of thick oil and preparation method and application thereof |
| abstract | The invention provides a self-breaking type temperature-resistant viscosity reducer for cold recovery of thick oil, which comprises the following components in percentage by mass: 37-55wt% of active component, 15-20wt% of additive, 5-8wt% of penetrating agent and the balance of deionized water; the active components comprise: fatty alcohol-polyoxyethylene ether sulfate, surfactin sodium and fatty acid alkanolamide in a mass ratio of (12-15): (0.5-1): 7-10). The application provides a from breaking milk type temperature resistant viscous oil cold recovery viscosity breaker, have fine complex nature between its each component, when being applied to the viscous oil of high temperature, high mineralization, can demonstrate apparent viscosity reduction performance to can also demonstrate better from breaking the emulsion effect after the viscosity reduction. Experiments show that when the viscosity reducer composition provided by the application is used as a displacement fluid, the viscosity reduction rate and the dehydration rate are both better than the effect of various surface active components when the surface active components are used independently, and the viscosity reducer composition has a good synergistic effect. |
