Abstract

The invention relates to a distributed temperature testing system and method for a hot dry rock deep well. The system comprises a distributed optical fiber temperature collection device, a logging winch, a well descending device and a temperature measuring optical cable, wherein the distributed optical fiber temperature collection device is used for completing collection of temperature along the temperature measuring optical cable and data processing; the logging winch is used for containing and transporting the temperature measuring optical cable and further used for providing a power source for fixed-depth and uniform-speed descending and winding of the temperature measuring optical cable; the well descending device is used for mechanical fixation and guidance for descending and winding of the temperature measuring optical cable; and the temperature measuring optical cable serves as a temperature sensing element and a data transmission channel. The system and the method achieve distributed temperature measurement of the hot dry rock deep well, and have the characteristics of resisting high temperature and high pressure, resisting electromagnetic interference, being free of limitation of severe environments like complex geometric space, and the like.

Description

Technical field [0001] The invention relates to a distributed optical fiber sensing detection technology, in particular to a distributed temperature detection system used in a deep well of dry hot rock. Background technique [0002] The national survey and evaluation of geothermal resources carried out during the "Twelfth Five-Year Plan" period shows that my country is rich in hot dry rock resources, has significant benefits in energy conservation and emission reduction, and has broad prospects for exploration and development. During the "13th Five-Year Plan" period, it is necessary to further carry out investigation and evaluation of hot dry rock resources, gradually ascertain the distribution of geothermal resources in key areas, evaluate the amount of geothermal resources, mineable resources and mining potential, and delineate several prospects with prospects for exploration and potential for power generation and heating. In the hot dry rock target area, carry out hot dry rock...
