| 摘 要： | 针对渤海稠油油田冷采低产低效井,通过室内实验研究了多元热流体增产引效工艺在非热采完井稠油油田解堵及增产效果。室内实验结果表明:多元热流体解堵后,采油指数可恢复到初始采油指数的35%左右;同时多元热流体对稠油冷采井具有明显增产作用,多元热流体吞吐周期内采油速度较冷采有明显提高,平均采油速度由4.65 mL/min提高至8.37 mL/min,累计增油量220 mL。

| Abstract: | In this paper, aimed at the wells with low production and efficiency under cold production, the simulation treatments of multi-component thermal fluid flood have been studied through the experiments. The results show that after the blockage reliving of multi-component thermal fluid flood, the productivity index has been recovered to 35% of the original productivity index. Meanwhile, the effect of multi-component thermal fluid flood is significant for wells under cold production. During the period of flooding, the rate of oil production has been obviously increased. The average rate of production is improved from 4.65 mL/min to 8.37mL/min. |
