| titleOfInvention | Viscosity reducing agent for heavy oil and viscosity reducing cold recovery method for heavy oil |
| abstract | The invention discloses a heavy oil viscosity reducing agent and a heavy oil viscosity reducing cold recovery method. The heavy oil viscosity reducer includes independently: active polymer viscosity reducer, and sulfonate type anionic surfactant and/or sodium carbonate. The invention can achieve "from inside to outside" viscosity reduction, can spontaneously contact with heavy oil without stirring indoors, quickly disperse heavy oil, strip, carry, migrate, effectively reduce viscosity and remove plugging, and is beneficial to heavy oil formations Flow and wellbore lift. The field test effect of the present invention is remarkable, and the oil increase cost per ton of oil is about 30%-50% of the previous steam stimulation cycle. Moreover, the invention has simple construction technology, safe and reliable operation, perfects the current heavy oil development mode, improves the development benefits of heavy oil reservoirs, and has wide application prospects and popularization value. |
