Abstract
The utility model relates to an oil pipe electric heater unit that is used for paraffin removal of oil recovery well in oil field or oil recovery. The electric oil well is characterized by comprising a mobile electric delivery vehicle, a power supply control cabinet, a cable winch, an input cable, an output cable, a well head connector, an underground cable, an insulated sucker rod, a centralizer, a contactor, an insulated oil pipe short circuit and an oil pipe. The utility model discloses simple and practical can popularize and apply in the oil field.
Description
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.
