Abstract

The utility model relates to an electric oil pipe heating unit used for removing paraffin or oil extraction in oil field, comprising a moveable power supply vehicle, a power supply control cabinet, a cable hoist, an input cable, an output cable, a wellhead connector, an underground cable, an insulated sucker rod, a centralizer, a contactor, an insulated oil pipe short connector and an oil pipe. The power supply control cabinet, the cable hoist, the input cable and the output cable are arranged on the movable power supply vehicle; the wellhead connector is arranged on one side of a big four-channel bushing; the underground cable, the insulated oil pipe short connector, the centralizer, the contactor and the insulated sucker rod are embedded into the shaft before oil well operation for periodically heating the oil well for oil extraction or periodically heating the well pipe for paraffin removal on a plurality of oil wells. The utility model has the advantages of lower investment and easy management, increased rate of equipment utilization and prevention the wellhead equipment from being stolen. The utility model also has the advantages of simplicity, practicality and oil field popularization.

Description

A kind of oil pipe electric heater unit
Technical field
The utility model relates to a kind of oil pipe electric heater unit that is used for oil well wax removal or oil recovery.
Background technology
In order to guarantee that oil well normally exploits, some hypercoagulation oilfields or viscous crude field often adopt oil pipe electrical heating oil production technology technology to recover the oil, and its shortcoming is that every mouthful of well well head of this technology needs electrical power control cabinets, and cost is about 50,000 yuan, and disposable input is bigger.For regular heating oil recovery well or regularly heat the wax removal well, utilization rate of equipment and installations is lower.
Summary of the invention
Task of the present utility model is to provide a kind of oil pipe electric heater unit that is used for oil well wax removal or oil recovery, adopt this device, can be with an electrical power control cabinet to many mouthfuls of regular heating oil recovery wells or regularly heat the wax removal well and provide power supply at different time, reduce investment outlay, convenient management improves utilization rate of equipment and installations.
The utility model is to realize like this, it send electric car by flowing, electrical power control cabinet, cable hoist, the input cable, output cable, connector of well top, downhole cable, the insulation sucker rod, centralizer, contactor, insulation oil pipe short circuit, oil pipe is formed, its assembling mode is: electrical power control cabinet, cable hoist, the input cable, output cable is contained in to flow and send on the electric car, connector of well top is contained in well head big four sleeve pipe one side, contactor, centralizer, downhole cable, insulation oil pipe short circuit, be lowered in the pit shaft in advance during the operation of insulation sucker rod oil well, wherein insulate and arrive under the oil pipe short circuit apart from about 15 meters at well head, be connected with oil pipe up and down, downhole cable top is connected with connector of well top, the bottom is connected with the oil pipe of insulation oil pipe short circuit bottom, centralizer is contained in the oil pipe outside, contactor is contained in oil pipe bottom certain depth, and the insulation sucker rod is contained in below the polished rod.
During use, will flow and send electric car to reach to need the heated well well head, output cable is connected with connector of well top, the input cable is connected with the oil wells in field power supply, regulates the extremely suitable voltage of electrical power control cabinet, electric current and heats to oil well and get final product.After heating finishes, deenergization will import, output cable is recovered on the car, and car is reached next well site, and required well is heated.
The utility model novel structure, simple, cost is low, can be used for many mouthfuls of regular heating oil recovery wells or regularly heats the electrical heating of wax removal well oil pipe, reduces investment outlay, and convenient management improves utilization rate of equipment and installations, prevents the stolen mistake of wellhead equipment.
