摘　　要：针对J-99块毗邻J1-01井地热水的实际情况,为了提高J-99块稠油开发效果,在对地热水水质及其与该块油层配伍性研究的基础上,室内开展了地热水驱提高稠油采收率实验研究。研究结果表明,60～85℃范围是提高采收率幅度对地热水温度变化最敏感的区域,其间地热水驱采收率的提高幅度由3.39%增大至9.84%;不同温度地热水有一个有效注入量,地热水温度越高,有效注入量越大,实际注入地热水为70～85℃时,累计注入量以1.5PV为宜。该项研究为J-99块普通稠油利用地热水驱提高采收率提供了依据。Experiment research of enhanced heavy oil recovery by geothermal water drive has been conducted for J-99 block based on compatibility study of geothermal water quality in the adjacent well J1-01 with the reservoir. The result of experiment shows that 60～85℃ is the most sensitive range of EOR to geothermal water temperature. Within this range, the recovery factor increases from 3.39% to 9.84%. Geothermal water of different temperature has a certain effective injection rate. The higher the temperature of geothermal water is, the larger the effective injection rate is. When injected geothermal water is at 85℃, it is better to inject 1.5 PV. This research provides basis for EOR by geothermal water drive in J-99 conventional heavy oil reservoir.
