Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that there are the following defects: the installation method of the temperature-sensing optical fiber in the related technology is to set a counterweight at the lower end of the temperature-sensing optical fiber, and lower it into the well through the gravity of the counterweight and the self-weight of the temperature-sensing optical fiber. At the bottom, during the process of pumping water through the pump, the temperature-sensing optical fiber located in the well is entangled under the disturbance of the water flow, so it may affect the pumping process

Embodiment 1

[0035] The embodiment of this application discloses a geothermal well temperature-sensing optical fiber temperature measurement system, refer to figure 1 , including a temperature-sensing optical fiber 1 and a counterweight 2, the temperature-sensing optical fiber 1 is connected to a wireless transmission device (not shown in the figure), a casing 3 is arranged on the inner wall of the well body, and the temperature-sensing optical fiber 1 passes through the counterweight 2 Lowered to the bottom of the well body, the counterweight 2 is fixedly connected to the end of the temperature-sensing optical fiber 1 extending into the bottom of the well; since the temperature-sensing optical fiber 1 near the pump pipe may be disturbed by the water flow during the process of pumping water from the well body, Bending occurs, in order to make the temperature-sensing optical fiber 1 not easy to be entangled under the disturbance of the water flow, referring to the figure, the fixed block 21,...

Embodiment 2

[0046] The difference between the embodiment of the present application and the first embodiment is: refer to image 3 , the elastic abutment part 5 is an air bag, the lower end of the air bag is fixedly connected on the telescopic block 22, the upper end of the air bag is fixedly connected with the fixed rod 6, the air bag is an air bag made of high temperature resistance and waterproof material, and the gas injection port of the air bag is close to the wellhead. The airbag is filled with gas, and when the sleeve tube 3 deforms outward, the distributed optical fiber 4 is pressed against the sleeve tube 3 under the action of the airbag.

Description

technical field [0001] The present application relates to the field of temperature-sensing optical fiber temperature measurement, in particular to a temperature-sensing optical fiber temperature measurement system for geothermal wells. Background technique [0002] Geothermal energy is a natural new energy source. When utilizing the heat energy of geothermal wells, it is first necessary to find out the change and distribution of underground temperature. [0003] The temperature measuring device of the geothermal well in the related art includes a temperature-sensing optical fiber, a wireless temperature-sensing optical fiber demodulator and a data receiving storage. The temperature-sensing optical fiber is vertically arranged in the geothermal well. Connect the wireless temperature-sensing optical fiber demodulator, the wireless temperature-sensing optical fiber demodulator communicates with the data receiving storage, and uses the measuring tube and temperature-sensing opti...
