| 摘 要： | 采用室内模拟的聚合物驱采出液,研究了聚合物含量对渤海油田聚驱采出液破乳效果的影响,通过油水界面动态界面张力的测定,对破乳机理进行了探讨。结果表明,油溶性高分支破乳剂ICO-89针对模拟聚驱采出液具有较好的破乳效果,对于ρ(聚)=50 mg/L的模拟采出液,破乳2 h脱水率达到85%,随着聚合物含量的增加,脱水率呈下降趋势,当ρ(聚)=300 mg/L时,破乳2 h脱水率降至81%。破乳剂的分子结构与油水界面吸附能力的强弱是影响破乳脱水的两个重要因素。 |

| Abstract: | The influence of polymer on the demulsification of polymer flooding produced fluids in Bohai oilfield was studied by simulated polymer flooding produced fluids,then the mechanism of demulsification was discussed using the dynamic interfacial tension measurements.The highly branched oil-soluble demulsifier ICO-89 was effective to the simulated polymer flooding produced fluids,and the demulsification efficiency became lower with the increase of polymer concentration.With ICO-89,the dehydration ratio of produced fluids(ρ(polymer)=50 mg/L) was 85% after two hours;when ρ(polymer)=300 mg/L,the dehydration ratio fell to 81%.Structure of the demulsifier and the interfacial adsorption capacity are two important factors on the demulsification efficiency. |
| Keywords: | polymer flooding simulated produced fluids demulsifiers mechanism of demulsification dynamic interfacial tension |
