Problems solved by technology

[0007] The purpose of the present invention is to solve the technical defects of the existing vehicle-mounted drilling and workover rig, and provide a dual-capacity hydraulic energy storage workover rig with emergency function
During the operation, the kinetic energy delivered by the drilling tool is converted into the hydraulic energy of the hydraulic accumulator. During the lifting operation, the hydraulic accumulator works together, which reduces the rated power of the required motor and overcomes the problems of the existing vehicle-mounted drilling and repairing machine

Abstract

The invention provides a dual-capacity hydraulic energy storage workover rig with an emergency function. The vehicle-mounted drilling and repairing machine uses a motor and hydraulic motor dual-power operation mode, a hydraulic motor also serves as an emergency power source, and the hydraulic motor can be driven by an energy accumulator or an external power source. In the operation process, kinetic energy issued by a drilling tool is converted into hydraulic energy of the hydraulic energy accumulator, the hydraulic energy accumulator does work together during lifting operation, the rated power of the required motor is reduced, and the problems of an existing vehicle-mounted drilling and repairing machine are solved.

Description

technical field [0001] The invention relates to a hydraulic energy storage vehicle-mounted drilling and repairing machine with emergency and power compensation functions, which belongs to the field of oil drilling development. Background technique [0002] The vehicle-mounted drilling and workover rig is a specialized petroleum exploration equipment used for drilling and workover. It is mainly used for lifting and sending out drill pipes, oil pipes, and sucker rods, as well as wellbore repairs and window openings. At present, most of the vehicle-mounted drilling and repairing machines use diesel engines as the power source, which has low efficiency and serious environmental pollution. With the in-depth development of oil exploration and development, many drilling wells are currently located in densely populated areas such as residential areas, commercial areas, and farmland. The problem of high noise of traditional vehicle-mounted drilling and repairing machines cannot be ig...
