Oil/electric integrated power wheel-type workover rig

Abstract

The invention belongs to the field of oil-water well workover operation devices and in particular relates to an oil / electric integrated power wheel-type workover rig. The rig comprises a diesel engine (12), a hydraulic torque converter, an automatic gearbox, a transmission shaft, a winch barrel and a variable frequency electric drive system which are arranged on a vehicle body (14), wherein the variable frequency electric drive system comprises a variable frequency motor (1), a dual-power mixing commutator (2), a coupling (11), an oil pump motor (3), a hydraulic pump (4) and a power supply; the output shaft of the variable frequency motor (1) is fixedly connected with the coupling (11) of the dual-power mixing commutator (2); the output power of the dual-power mixing commutator (2) is conveyed to a winch via a chain wheel (13); the output shaft of the oil pump motor (3) is fixedly connected with the input shaft of the hydraulic pump (4); and the power supply is used for providing electric energy to the variable frequency motor (1) and the vehicle body (14). The rig has low manufacturing cost, good energy saving effect and high equipment use ratio and is convenient to operate.

Description

technical field [0001] The invention belongs to the field of oil-water well workover operation devices, in particular to an oil / electricity comprehensive power wheeled workover machine. Background technique [0002] The wheeled workover rig is currently the main equipment for oil and water well workover operations in the oil field. Its field construction conditions are poor and the continuous operation time is long; resulting in an increase in the failure rate of the equipment and energy consumption indicators for standard wells; especially in 2008, Due to the sharp increase in the prices of various raw materials, the energy consumption and maintenance costs of workover equipment have become the main cost of workover operations. In recent years, with the higher requirements of energy saving, safety and environmental protection for workover operation technology put forward by enterprises, new electric drive and hydraulic drive workover rigs are gradually becoming the developm...

Problems solved by technology

In actual field application, electric workover rigs, in addition to high purchase costs, have certain requirements for wellsite power equipment (some remote wellsites lack corresponding power supporting facilities); at the same time, the existing wheeled workover rigs in oil fields are far from meeting The scrapping cycle is unlikely to be eliminated at one time; therefore, there are certain limitations in large-scale promotion and application
