Geothermal energy is a clean energy source; its development and utilization are mainly realized by drilling engineering, and the value of development and utilization are determined by the amount of geothermal resources (water yield). In practice, due to the complexity and uncertainty of the stratum, the water yield and water temperature can not reach the expectation, especially in water-shortage mountainous bedrock area, development and utilization of clean energy source are seriously affected by low water yield and temperature indexes. Staged hydraulic fracturing technology by using fracturing truck and drilling pump is applied in serious water shortage area of Westen Henan for the first time, water output grows 3 times for low yield geothermal well and reached the expected target.It can provide reference for the future development and utilization of geothermal and groundwater resources in the bedrock area.
