摘要
Comparison of new and old injection technologies in field test in the medium-fine sand aquifer of the Zhengbian new region shows that the new injection technology is much better than the old(traditional) injection technology in well completion time,recharge quantity,etc.The unit recharge quantity and the ratio of pumping quantity to recharge quantity rise greatly and the stable time for recharge is much shorter.According to pumping and recharge test of multi fall path(lift),we establish the relationship equation between the recharge quantity and the groundwater levels and well spacing.Based on the research results,the groundwater heat pump system may realize the heat transfer model with pumping and recharging in a standing column well system in the Zhengbian new region.The cost saving rate on heat transfer system(outdoor) reaches 50%.The old problem of injection difficulty in the medium-fine sand aquifer is solved.
