It is critical to determine how the well group arranges for application of the GWSHP system. Based on the fact that water movement is the most important factor influencing heat transfer in an aquifer, this paper presents a two-step analysis method and analyzes the inter-well thermal transfixion method as follows. First, we forecast the least influence radius through calculating the thermal diffusion function of aquifer. Then, we perform an analysis on the inter-well thermal transfixion, using the streamline analysis method and doing a quantitative analysis of the effects that inter-well distance and flux have on it. We discuss the well group arrangement and puts forward optimal scheme by means of the thermal diffusion and streamline simulation.
