摘要:

利用就地CO2 在多孔介质中降低原油粘度技术是一种新研制开发的提高原油采收率有效技术,研究了就地CO2技术降低原油粘度的测定办法,提出了阻力系数法。对单液法和双液法就地CO2体系在填砂管中对原油的降粘能力进行了实验评价,结果表明:在油藏条件下,当原油粘度为12904.1mPas,温度70℃,压力6MPa时,单液法可以使原油粘度降低42.15%,双液法可以使原油粘度降低52.69%。证明阻力系数法测定原油粘度下降是可行有效的。

Abstract: It is a new and effective technology to enhance oil recovery by using insitu CO2 to reduce oil viscosity. The authors research the method to determine the oil viscosity reduction by using insitu CO2, and bring forward the method of resistance coefficient. The evaluation is done to the single liquid system and dual liquids system of insitu CO2 ability of reducing oil viscosity in the sand pack. The results indicate that the single liquid system can reduce the oil viscosity by 42.15%, and the dualliquid system can reduce the oil viscosity by 52.69% when the oil viscosity is 12904.1mPa•s, the temperature 70℃, the pressure 6MPa. It shows the method of resistance coefficient to determine the degree of viscosity reduction is feasible and effective.
