Abstract

The invention discloses a power battery energy storage type electric workover rig, which comprises a workover rig special chassis. An alternating-current frequency conversion motor is arranged on theworkover rig special chassis and connected with the output end of an electric energy distribution control unit; the input end of the electric energy distribution control unit is connected with a powerbattery pack; the electric energy distribution control unit controls the rotating speed of the alternating-current frequency conversion motor; during travelling and lifting operation of the electricworkover rig, the power battery pack supplies power to the alternating-current frequency conversion motor; and during lowering operation of the electric workover rig, the alternating-current frequencyconversion motor generates electricity and stores the electricity in the power battery pack. The problems of high noise, high energy consumption, high pollution and the like of a conventional dieselengine workover rig can be solved, the problem of operation power and travelling power configuration waste of an existing electric workover rig is further solved, and in addition, the problem that a super capacitor energy storage workover rig needs to wait for charging at the lifting interval is solved.

Description

Technical field [0001] The invention belongs to petroleum machinery, and particularly relates to an electric workover rig. Background technique [0002] The workover rig is the main equipment used to repair the developed oil wells. Its main function is to realize the lifting and lowering operations of the sucker rod and tubing in the oil well. [0003] The workover rigs on the market generally use diesel engines as the driving and operating power of the workover rig. Diesel engines have the advantages of large horsepower and independent operation without relying on the grid capacity of the wellsite. The workover load is a periodic load, and the load fluctuates greatly. Configuring the diesel engine power according to the maximum load often results in waste of diesel engine power consumption. In addition, the diesel engine itself has problems such as low efficiency, heavy pollution, and high efficiency. These problems run counter to the country's sustainable development and increa...
