The invention discloses a precise stratum freezer and an operation method thereof. The precise stratum freezer comprises a freezer head, a freezer outer pipe, a liquid supply hose for full-length temperature measurement in the freezer and a pipeline connected with a liquid distribution main pipe and a liquid collection main pipe, and the freezer head is provided with a liquid supply port and a liquid return port; the liquid supply port and the liquid return port are connected to the liquid distribution main pipe and the liquid collection main pipe through a high-pressure rubber pipe, a valve and a flow meter respectively; and the liquid supply hose is arranged inside the freezer and penetrates through the overall length of the freezer outer pipe to extend. Temperature measuring assembliesare embedded in the thickness range of the pipe wall of the liquid supply hose, the temperature measuring assemblies are embedded in the thickness range of the pipe wall of the liquid supply hose in the longitudinal full length direction, each temperature measuring assembly comprises a temperature measuring single double-core cable and a sheet type temperature measuring sensor and can measure thetemperature change in the length range of the freezing outer pipe in real time, the high-pressure rubber pipe, the control valve and the flow meter serve as a part of the precise freezer to regulate and control the flow and the refrigerating capacity, and stratum freezing engineering technology development is promoted.
Description
technical field [0001] The invention belongs to the technical field of stratum freezing, and in particular relates to a precision stratum freezing device and an operating method thereof. Background technique [0002] In the current artificial formation freezing method construction, the monitoring of the freezing temperature field and the development of the freezing wall is mainly realized by setting the temperature detection in the temperature measuring hole in the formation, and laying a temperature measuring sensor in the temperature measuring hole, through several temperature measuring The temperature data obtained by the hole can be used to judge the temperature situation of the whole field and calculate the development of the frozen wall. Therefore, outputting data through a limited number of temperature-measuring holes inevitably has the disadvantage of "one-hole view" and cannot reflect the overall formation freezing situation. [0003] In addition, the position of t...
