The invention provides a heat energy conduction device for conducting underground heat energy by utilizing an oil-string casing. The heat energy conduction device for conducting the underground heat energy by utilizing the oil-string casing comprises a box body, a lifting mechanism, an air and water inlet mechanism, a mounting mechanism, a heat conduction mechanism, a sealing mechanism and two conveying pipes, wherein the lifting mechanism is arranged at the top of the box body, the air and water inlet mechanism is welded at the bottom of the box body, the mounting mechanism is welded to the interior with the cross section in a parallelogram structure of the box body, the mounting mechanism comprises a limiting head, a lantern ring, a pressure spring and a mounting column, the heat conduction mechanism is arranged in the box body, and the heat conduction mechanism comprises a limiting sleeve, a connecting pipe, a connecting head and the oil-string casing. The heat energy conduction device for conducting the underground heat energy by utilizing the oil-string casing is small in occupied area, uniform in heat absorption and convenient to install.
Description
technical field [0001] The invention relates to the technical field of underground thermal energy conduction, in particular to a thermal energy conduction device that conducts underground thermal energy through an oil layer casing. Background technique [0002] Oil layer casing, also known as production casing, is the last layer of casing in the oil and gas well casing program. It goes down from the wellhead to below the oil and gas layer. The oil layer casing is the channel for oil and gas to isolate oil and gas from all formations, ensuring Oil and gas pressure does not leak. After the oil layer casing is put into production, its quality must be guaranteed to maintain a certain production life. [0003] At present, the oil layer casings in the thermal energy conduction devices that use oil layer casings to conduct underground heat energy are installed in a circular distribution, occupying a large area, absorbing heat unevenly, and are directly snapped inside the box durin...
