An energy storage workover rig

Abstract

The invention relates to the technical field of workover rigs, and discloses an energy storage workover rig, which includes an energy storage mechanism, which is fixedly installed inside the compartment of the workover rig body, the upper end of the worm runs through the upper end of the energy storage box, and the upper end of the worm The upper end is meshed with the worm gear; four sets of flywheel accumulators are vertically installed inside the energy storage box, and the reducer runs through the inner bottom of the energy storage box and extends into the gear transmission box; through four sets of flywheel accumulators with different energy storage levels It can be converted and used according to the working environment and industrial and mining needs during work, and the flywheel accumulator with reasonable power is used to work, which is more energy-saving; when the four sets of flywheel accumulators are working, the electric push rod is directly controlled by the PLC controller. Switching is realized and the operation is convenient; the supercapacitor battery pack and four sets of flywheel accumulators are used to match the main body of the workover rig, which has long service life, high efficiency, low maintenance frequency, good stability, and high power density. Fast response; able to meet various complex industrial and mining needs.

Description

technical field [0001] The invention relates to the technical field of workover rigs, in particular to an energy storage workover rig. Background technique [0002] The workover rig is mainly a common equipment used in the oil field for various oil and water well pipe lifting operations and downhole operations. The workover rig is often used to lift and lower the pipe string, and the operation of lifting the pipe string is an intermittent cycle process. The workover rig spends about 1 / 4 of the entire lifting cycle, while the time for auxiliary operations such as shackles and placing single strings takes up 3 / 4. [0003] When the workover rig is working, in order to meet the needs of quickly raising the pipe string, it is generally equipped with a high-power power machine, while in the workover process, only small and medium power is required for the lowering of the pipe string, cleaning of the wellbore, salvage of debris, and casing repair. The power machine can satisfy th...

[0003] When the workover rig is working, in order to meet the needs of quickly raising the pipe string, it is generally equipped with a high-power power unit, while during the workover process, only small and medium power is required for the lowering of the pipe string, wellbore cleaning, salvage of debris, and casing repair. The power machine is sufficient for use, and only one high-power machine is used to work, and the energy consumption is relatively high
