摘要
为解决大庆黑帝庙稠油粘度高,开采难度大的问题,开发了应用乳化降粘技术采该油藏的新方法。现场应用表明,开发的稠油乳化降粘剂耐低温,使用浓度小,明显降低稠油粘度及其在井筒及管线中的流压,同时不影响稠油破乳,具有较大的推广使用价值。
The recovery and transport of viscous crude oil in Daqing Heidimiao region were difficult for its high viscosity and low mobility. We developed viscosity reducer for emulsifying viscous crude oil. The results in oil field test revealed that, at low temperature(15℃)and low concentration of chemicals(0.5%),it had high emulsifying efficiency, excellent viscosity reducing capacity, corresponding emulsion was easily demulsified.
