Efficient combined-type geothermal well pipe structure

Abstract

The invention relates to an efficient combined-type geothermal well pipe structure. The efficient combined-type geothermal well pipe structure comprises two or more flow guiding pipes, two or more bearing pipes, solid-liquid filtering mechanisms, drainage pipes and a sealing plug. Every two adjacent flow guiding pipes and the corresponding two adjacent bearing pipes communicate mutually through connecting mechanisms correspondingly and are distributed coaxially. A plurality of flow guiding openings are evenly distributed in the side surfaces of the flow guiding pipes. Two or more guiding sliding rails are arranged in the flow guiding pipes and the bearing pipes correspondingly. The solid-liquid filtering mechanisms are slidably connected with the inner surfaces of the flow guiding pipes and the bearing pipes through the guiding sliding rails. The tail ends of the drainage pipes are embedded in the bearing pipes. According to the efficient combined-type geothermal well pipe structure, on the one hand, the working efficiency and quality of construction of a geothermal well can be effectively met, and on the other hand, high integration and modular design are achieved, and the flexibility and working efficiency of equipment market maintenance and part replacing operation are improved effectively while the equipment construction operation efficiency is improved.

Description

technical field [0001] The invention relates to a geothermal energy development and utilization equipment, specifically a high-efficiency combined geothermal well well pipe structure. Background technique [0002] At present, in the development and utilization of geothermal energy, geothermal resources such as hot water and hot gas are mainly developed and utilized through geothermal wells. Therefore, it is necessary to put the lower part of the well pipe equipment into the geothermal well, and then pump the geothermal resources in the geothermal well through the pumping station. Utilization, in order to improve the work efficiency and quality of geothermal resource collection operations and reduce equipment loss, it is often necessary to perform preliminary solid-liquid separation and filtration in the process of geothermal resource collection in geothermal wells.

[0002] At present, in the development and utilization of geothermal energy, geothermal resources such as hot water and hot gas are mainly developed and utilized through geothermal wells. Therefore, it is necessary to put the lower part of the well pipe equipment into the geothermal well, and then pump the geothermal resources in the geothermal well through the pumping station. Utilization, in order to improve the work efficiency and quality of geothermal resource collection operations and reduce equipment loss, it is often necessary to perform preliminary solid-liquid separation and filtration in the process of geothermal resource collection in geothermal wells. Currently, when performing such operations, it is mainly in The filter mechanism is installed at the front end of the well pipe, and then positioned in the geothermal well along with the construction of the well pipe. Although this well pipe structure can meet the needs of use, on the one hand, it causes a complex structure of the well pipe equipment, difficulty in installation and positioning, and low work efficiency. On the other hand, it also leads to the inability to maintain and replace the filter equipment in a timely, effective and flexible manner during the geothermal energy collection operation, which leads to the current geothermal energy collection operation, because the maintenance of the geothermal well filter equipment takes a lot of time. Manpower and material resources have seriously affected the reliability, stability and cost of geothermal energy collection operations. Therefore, in view of this situation, it is urgent to develop a new well pipe equipment for geothermal wells to meet the needs of actual use.
