Description

Technical Field

[0001] The utility model relates to the technical field of geothermal resource exploration, in particular to a casing of a remote monitoring device for drilling temperature and pressure used in geothermal exploration. Background Art

[0002] Temperature measurement and pressure monitoring are the most familiar scientific research methods for human beings. They play an important role in various aspects of earth science, from studying the formation and evolution of the earth, deep structure and tectonic structure, to the formation of mineral resources, climate change, ecological environment change, etc. Strengthening the monitoring and research of ground temperature and underground pressure can meet the needs of earth system research and promote faster and deeper development of related earth science research fields. Therefore, people have begun to pay extensive attention to the changes in the earth's temperature and pressure, and it is particularly important to measure the earth's temperature and pressure.

[0003] Since the surface temperature is easily affected by changes in the surrounding environment, in order to measure more real and accurate values ​​when measuring the earth's temperature and pressure, temperature probes can be inserted deep underground through prospecting drilling, oil drilling and other scientific research drilling to conduct long-term temperature and pressure measurements.

[0004] At present, there is no mature drilling temperature and pressure monitor shell. When conducting long-term monitoring of underground temperature and pressure, the temperature and pressure acquisition module and the power supply battery are placed in a PVC box. The waterproofing of the connection between the temperature measuring line and the box is solved by sealant. When the power supply of the equipment is insufficient, the box is opened and the battery is replaced. When reading data, the memory card in the acquisition module is pulled out and the data is read on the computer. Opening and closing the box back and forth like this can easily cause the sealant between the box and the temperature measuring line to loosen, which leads to poor sealing effect of the box, resulting in gaps, water leakage and short circuit of the internal electronic module.

[0005] Therefore, the utility model provides a housing of a remote monitoring device for drilling temperature and pressure for geothermal exploration to solve the above problems. Utility Model Content

[0006] 1. Technical issues to be solved

[0007] The utility model provides a casing of a remote monitoring device for temperature and pressure of a well drilling for geothermal exploration, aiming to solve the problem that the existing remote monitoring device for temperature and pressure of a well drilling for geothermal exploration proposed in the background technology has no formed casing. When long-term monitoring of underground temperature and pressure is performed, a temperature and pressure acquisition module and a power supply battery are placed in a PVC box, and the waterproofing of the connection between the temperature measuring line and the box is solved by a sealant. When the power supply of the device is insufficient, the box is opened and the battery is replaced again. When reading data, the storage card in the acquisition module is pulled out and the data is read on a computer. This results in a poor sealing effect of the box, which is prone to water leakage and other problems.
