Operation driving device of oil-electricity hybrid power workover rig

Abstract

The invention relates to the technical field of oil and gas development of oil fields, and discloses an operation driving device of an oil-electricity hybrid power workover rig. The operation drivingdevice comprises a permanent magnet synchronous motor and an angle transmission box, wherein a chain wheel is arranged at the power output end of a power shaft of the angle transmission box; the powershaft is rotationally connected with a bevel gear I and a bevel gear II, and is fixedly connected with a reversing shifting fork in the radial direction; the bevel gear I and the bevel gear II are respectively connected with the reversing shifting fork in a sliding manner in the axial direction of the power shaft, and are connected with a bevel gear III in an engaged manner; an input flange is arranged at the power input end of the power shaft of the angle transmission box; and the input flange is fixedly connected with a coupling, an output flange and the permanent magnet synchronous motor in sequence. Through the operation driving device of the oil-electricity hybrid power workover rig, a vehicle-mounted power system and a permanent magnet synchronous motor power system coexist to perform workover operation; vehicle-mounted power is adopted during migration between well sites; permanent magnet synchronous motor power is adopted during light-load workover operation; and hybrid powerof the vehicle-mounted power and the permanent magnet synchronous motor power is adopted during heavy-load workover operation, so that the energy conservation and the environmental protection are realized, and the workover operation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of oil and gas development in oilfields, in particular to an operation drive device for an oil-electric hybrid workover rig. Background technique [0002] At present, workover operations are an important measure to maintain the normal production of oil wells in the process of oil and gas exploration and development, and are of great significance to ensure stable and high production in oil fields. Workover rigs are widely used as the main equipment for workover operations. Traditional workover rigs mostly use diesel engines As a single power source, it has high energy consumption, high pollution, serious noise, cumbersome operation, and complicated construction. It has become the general trend to develop new types of operating equipment that are green, environmentally friendly, zero-pollution, and easy to operate. Although the network power workover rigs that have been used in the market currently replace the...

[0002] At present, workover operations are an important measure to maintain the normal production of oil wells in the process of oil and gas exploration and development, and are of great significance to ensure stable and high production in oil fields. Workover rigs are widely used as the main equipment for workover operations. Traditional workover rigs mostly use diesel engines As a single power source, it has high energy consumption, high pollution, serious noise, cumbersome operation, and complicated construction. It is an irresistible trend to develop new types of operating equipment that are green, environmentally friendly, zero-pollution, and easy to operate.

Although the network power workover rigs that have been used in the market currently replace the operating power with motor drive, due to the demand for operating power, the installation of a relatively large motor (generally above 90kW) cannot match the power of the well site transformer (below 50kW) installed in the oilfield now. Matching, and the matching transformer device of about 100-200kVA is inflexible during use and inconvenient to operate; the gas engine powered workover rig that uses LNG as fuel has the problem of inconvenient transportation and filling of LNG fuel
