渤海稠油热水驱驱油效率规律研究

Study on Oil Displacement Efficiency of Heavy Oil by Hot Water Flooding in Bohai Sea

为对比不同条件下热水驱开发效果,本文通过驱油效率实验对比了不同注入温度和不同注入速度条件下热水驱开发效果。热水驱的适宜注水温度推荐150℃;注水速度推荐100~150m^3/d;热水驱的驱油效率可以达到50%左右。

In order to compare the development effect of hot water flooding under different conditions,this paper compares the development effect of hot water flooding under different injection temperature and different injection speed by oil displacement efficiency experiment. Suitable water injection temperature for hot water flooding is recommended:150 C;water injection speed is recommended:100-150 m3/d;the oil displacement efficiency of hot water flooding can reach about 50%.
