According to the design requirements and geological characteristics, rotary drilling, mud pump positive cycle, cone bit, pressure by drill collar processes were adopted in the construction of Well WH-1. The formation structure and spatial distribution of aquifer within logging depth were got through geophysical logging. Good plugging effect was obtained by mud density reduction, viscosity enhancing, mud thickening and adding an appropriate amount of blocking agent. The pumping test shows the good water yield ability, good water abundance in geothermal reservoir aquifer and the water temperature is not affected by air temperature. The water temperature loss is small in the well flow test, which proves that the drilling and completion technologies are rational. The paper introduced the Well WH-1 about its drilling and completion technologies as well as pumping test results.
