Abstract
The distance between production and injection wells, distribution of wells and operation models of the pump system are the key determining factors of the system work efficiency. A new concept of flow transfixion is suggested by analyzing the general features of an aquifer. A couple numerical models of groundwater flow and heat transferring were established based on the basic theory of water-heat transferring in the aquifer. The interaction between flow and heat transfixions, and its significance to practical engineering were also analyzed. And then numerical analysis of the flow field and the temperature field for the pump system in one community of Xianyang City shows that the main factor of the formation of flow transfixion is hydraulic gradient, namely, the hydraulic gradient can be used to judge quantitatively whether the flow transfixion takes place or not. The effect of the injecting and pumping rate (Q) to the flow transfixion shows that the shorter occurrence time of flow transfixion, the more of the value of Q, and it is easier to occur flow transfixion for more of Q, and then to lead to occurrence of heat transfixion. In practical engineering, the occurrence of heat transfixion can be reduced by reducing the value of Q, and by increasing spacing of injecting and pumping wells.
