反滤回灌井是地下水库中一种有效的回灌设施,它由回灌井和井口的反滤层组成。完整反滤回灌井井流运动由反滤层的竖向流和完整井的水平流组合而成,文中提出了承压-潜水含水层中完整反滤回灌井稳定流的计算方法,结合实例说明了反滤回灌井的回灌量大大低于普通回灌井的回灌量,并分析了反滤层、井损、回灌堵塞和影响半径等因素对回灌量的影响。 Filter backfilling wells is an effective recharge facility in underground reservoirs, which consists of a backfill well and an antifilter layer at the wellhead. The wellbore flow in a complete filtration and recharge well is composed of the vertical flow of the anti-filtration layer and the horizontal flow of the complete well. In this paper, the calculation method of the steady flow in a complete backfill well in a pressure-subducting aquifer is proposed. The results show that the recharge volume of the filtration and recharge wells is much lower than that of the normal injection wells and the influence of the factors such as the filter layer, well damage, recharge plugging and the influence radius on the recharge volume is analyzed.
