Abstract

The sandstone geothermal recharge well wellhead device comprises a wellhead body, a drainage pipe, a recharge pipe, a water outlet pipe and an exhaust valve, the wellhead body is provided with a containing space, the containing space is divided into a first channel and a second channel, one end of the first channel is used for being communicated with a geothermal well, and the other end of the first channel is communicated with the water outlet pipe; one end of the second channel is communicated with the drainage pipe, one end of the recharge pipe is communicated with the water outlet pipe, the other end of the recharge pipe is communicated with the other end of the second channel, and the exhaust valve is arranged on the second channel. According to the sandstone geothermal recharge well mouth device, gas in the recharge process is exhausted in time through the exhaust valve of the second channel, and the efficiency and quality of geothermal well water recharge can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of wellheads of geothermal wells, in particular to a wellhead device for sandstone geothermal recharge wells. Background technique [0002] With the serious damage to the environment caused by traditional energy sources, renewable clean energy has become the current research and development trend. Geothermal resources have unique advantages such as cleanliness, high efficiency, stability, and safety. Therefore, in recent years, geothermal development has developed rapidly. However, in geothermal energy There are many problems in the utilization process, especially the problem of geothermal tail water recharge. For example, after the geothermal tail water passes through the recharge filter device, there is gas in the pipeline during the recharge process, which seriously affects the recharge; the recharge well is replaced The heat station is far away, and there are various suspended solids and sand particles i...
