【 摘 要 】

In order to find out the recharge ability of the sandstone reservoir in the Dongying formation of Liaocheng City, the recharge test of geothermal tail water was carried out. The results showed that under the natural conditions, when the recharge of geothermal tail water was 27m3/h, the recharge ability was lost. Under the pressure of 0.2Mp, the recharge capacity tended to decay with the recharge time increasing, The maximum recharge volume is 20m3/h. From the analysis of the geological condition of the thermal reservoir, the pressure condition of the water head and the recharge ability, we find that the reirrigation capacity of the sandstone reservoir in Dongying formation of Liaocheng is weaker.
