摘要：针对河南油田超稠油黏度高,流动性差,开采和输送困难等现状,本文展开对河南油田超稠油的乳化降黏研究。得到优化的复合降黏剂F2配方,其中,乳化降黏剂主剂RA-1、稳定剂聚丙烯酰胺、助剂碱质量比为1∶0.25∶0.36,在F2总加剂量为0.483%(占原油乳状液的质量百分比),乳化温度70℃,油水质量比为7∶3下,可以制得均匀、稳定的O/W型超稠油乳状液,超稠油的黏度由240 Pa·s(50℃)降到其乳状液的42.8 mPa·s(50℃),降黏率高达99.98%。文中同时对降黏机理进行了探讨。
According to the problems of high viscosity,poor liquidity and difficulties in exploitation and transportation of Henan extra-heavy oil,the research on reducing viscosity of extra-heavy oil in Henan oilfield by emulsifying was carried out. The optimized composite reducing viscosity agent F2 comprised main agent RA-1,stabilizer polyacrylamide and additive alkali at the mass ratio of 1∶0.25∶0.36. When the dosage of the F2 was 0.483% in the emulsion and the oil to water mass ratio was 7∶3,the stable O/W emulsion was obtained at the temperature of 70℃. At the temperature of 50℃,after emulsified,the viscosity of the extra-heavy oil(240 Pa·s)could reduce to 42.8 mPa·s(50℃),and the viscosity reducing rate was up to 99.98%. In addition,the mechanism of viscosity reduction by emulsifying was studied.
