| titleOfInvention | A kind of heavy oil viscosity reducing agent and heavy oil viscosity reducing cold recovery method |
| 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 realize "inside-out" viscosity reduction, can spontaneously contact heavy oil without stirring in the room, quickly disperse heavy oil, peel, carry, migrate, effectively reduce viscosity and remove blockage, and is beneficial to heavy oil formations Flow and wellbore lift. The on-site test effect of the invention is remarkable, and the oil-increasing cost per ton of oil is about 30%-50% of the previous steam huff and puff cycle. In addition, the invention has simple construction process, safe and reliable operation, improves the current development mode of heavy oil, and has broad application prospect and promotion value when the development benefit of heavy oil reservoir is mentioned. |
