In this paper, MATLAB software is used to simulate the influence of parameters of different heat source wells on pumping temperature in groundwater source heat pump system. The absolute value of horizontal permeability coefficient of aquifer will not affect its pumping temperature, but when the permeability coefficient ratio increases from 1 to 10, the pumping temperature decreases by 1.1°C; When the specific heat capacity increases from 2000 kJ / m3 · °C to 3000 kJ / m3 · °C, the pumping temperature decreases by 0.8 °C; When the degree of thermal dispersion increases from 1m to 3m, the pumping temperature decreases by 0.4°C.
