通过对胜利油田商 1 3 2 2单元进行的CO2 驱室内实验研究 ,确定了商 1 3 2 2单元的最小混相压力、原油与CO2体系的基本物性、CO2 对原油的膨胀降粘效果以及现场进行驱替时的合理注入方式。提出了胜利油田CO2 驱室内研究的一般思路 ,对胜利油田利用CO2 驱提高低渗透油田采收率具有一定的指导意义。
Based on the laboratory experiments of CO2 flooding in Shengli Oilfield Company, the minimum miscibility pressure of commercial units, basic physical properties of crude oil and CO2 system, the effect of CO2 on crude oil swelling and viscosity reduction and on-site Reasonable injection method of displacement. Proposed the general idea of indoor research on CO2 flooding in Shengli Oilfield, which is of guiding significance for the use of CO2 flooding in Shengli Oilfield to enhance the recovery of low permeability oilfield.
