摘要
为了解聊城市城区东营组热储层回灌能力,利用地热井对古近纪东营组热储层开展了同层对井的自然回灌和压力回灌试验。结果表明,在自然回灌条件下,回灌量不宜大于20 m3/h;在加压回灌条件下,压强为0.2 MPa、回灌量为20 m3/h时,随着回灌时间的延长,回灌量呈现衰减趋势。通过对热储层地质条件、回灌能力进行分析,认为在该条件下,宜采取一采多灌的回灌方式。
To find out the capability to geothermal reservoirs recharge of Dongying formation in urban district of Liaocheng City,by using geothermal wells test of geothermal reservoirs in Paleogene Dongying formation in the same layers under the natural condition and pressure condition. As showed by the results,in the natural condition,the quantity of water recharge should not exceed 20 m^3/ h,in the pressure condition,the pressure equal to 0. 2 MPa,and the quantity of water recharge equal to 20 m^3/ h,as the extension of recharge time,the quantity of water recharge showed a trend of attenuation. Through analysis on geological condition,recharge capability of geothermal reservoirs,it is regarded that under this present condition appropriate to take one pumping and more irrigation method.
