Problems solved by technology

When using this method, the mist of the steam reduces visibility, affects normal production operations, easily causes safety accidents, and is expensive
Local overheating of the blowtorch can easily burn it out, causing fires and causing huge economic losses. Moreover, the relevant operating regulations clearly stipulate that the use of open flames is strictly prohibited in the well site

Abstract

A movable anti-explosion pressure-resistance gas-liquid heater is used to resolving the block of tubes. The invention arranges an anti-explosion electric heater on the vehicle, several electric heating tubes in the pressure container and fixed at the flange of pressure container, and several diverting plates along the axle of pressure container fixed at the inner wall of container. The inlet and outlet of heating medium are arranged at the left and right ends of container. The pressure container is arranged with a discharge safe valve. The automatic electric controller and temperature automatic controller are mounted on the vehicle. Compared with present technique, the invention can save energy and improve safety.

Description

technical field [0001] The invention relates to electromechanical heating technology. The equipment has mobility and is mainly used to solve the freezing and blocking problems of tools, equipment and pipelines in oil fields and drilling operations. Liquid heating; it can be extended to explosion-proof and aseptic production sites. Background technique [0002] In the petroleum industry, during the production process of drilling and workover operations in winter, due to the temperature below 0°C, equipment (oil pipelines, gas and water pipelines, wellhead gate valves, elbow joints, etc.) often freeze and block, and wellhead tools (pipe wrench , elevators, etc.) and the freezing phenomenon of drilling tools and the freezing and blocking of wellhead oil pipelines affect the normal safe production process. [0003] At present, the usual methods for solving the freezing and blocking problems in the production of drilling operations in winter are to scald with steam and bake with...
