Abstract

The invention discloses an ice and frost removing device and an ice and frost removing method. The device comprises a shell, a heating chamber, a flow guide chamber and a drying chamber are sequentially arranged in the shell, the heating chamber, the flow guide chamber and the drying chamber sequentially communicate, a heating element and an air supply element are arranged in the heating chamber,the air supply element is arranged on the side, away from the flow guide chamber, in the heating chamber, the heating element is arranged on the side, close to the flow guide chamber, in the heating chamber, the heating element and the air supply element are externally connected with a power supply through cables respectively, a flow guide element is arranged in the flow guide chamber and used forchanging airflow passing through the flow guide chamber into spiral airflow, an opening is formed in one end of the drying chamber, the opening of the drying chamber is used for placing an iced and frosted tubing head or oil rod screw thread, and the diameter of the opening end of the drying chamber is larger than the outer diameter of the tubing head or oil rod screw thread.

Description

technical field [0001] The invention belongs to the technical field of oil production pipeline treatment, and in particular relates to a de-icing device and a de-icing method. Background technique [0002] In the maintenance and repair process of underground operations in oil exploitation, due to the low temperature in severe winter, the oil pipe rods placed on the ground must be cleaned of wax by the boiler car before entering the well, and the threads will freeze after the wax is removed; or logging in the oil production well When the gas condenses in the casing, condensate oil is produced, and water is brought out at the same time, so that the casing head of the test well freezes, causing the casing to be blocked by ice during well logging and unable to perform well logging. [0003] The conventional deicing and defrosting methods currently adopted are: [0004] Brush the oil rod screw thread after the boiler car thorn washing with a wire brush in turn to clean the frost...
