Abstract
The utility model relates to an oil-exploitation and wax removal device for an electric oil pipe. An insulation sucker rod is arranged between a polish rod and a sucker rod. The upper part of an oil pipe is connected with an insulation short section. The oil pipe and a sleeve pipe are separated and insulated by an insulation centralizer. A fire wire of a power source is connected with the oil pipe on the lower part of the insulation short section through a conducting wire. A zero line is connected with the sleeve pipe through a communicating device on the lower part to form a heating loop. The utility model has the advantages of compact structure and good exploitation and wax removal effect. Insulation exists between the oil pipe and a ground height.
Description
The utility model is the corollary apparatus during viscous crude and high waxy oil well recover the oil.
At present, each oil field adopts sucker rod to move up and down heating and simple oil pipe heating solves mining problem in viscous crude and the thermal recovery of high waxy oil well.Need to use fixed power source (as needs transformer and corollary equipment), cost height, maintenance rate height.Because of its heating sucker rod moves up and down, electric pole leakage, cable fracture take place aborning easily and short circuit, causing has a power failure stops production.
The purpose of this utility model is, provides a kind of and both can adopt fixed power source, can adopt the electric heating oil pipe oil recovery paraffin removal unit of portable power source again.
The technical solution of the utility model is:
Both can adopt portable power source (as: vehicle-mounted diesel power generation unit, transformer etc.), and can adopt fixed power source (wiring near the power supply) again, be live wire with static oil pipe, and sleeve pipe is zero line, receives on the ground electrical power control cabinet by the down-hole linker.Electric current by on the oil pipe by making its heating.Connect by insulating short section between first and second root oil pipe below the ground, thereby guarantee oil pipe and ground insulation.Cut off insulation by the insulation centralizer between down-hole oil tube and the sleeve pipe.Use this device to need to use the special well head of energy outgoing cable line.The live wire of ground portable power source (or fixed power source) is received on the oil pipe at the following position of insulating short section, down-hole through lead, electric current passes to the shaft bottom through lead and oil pipe, receive on the sleeve pipe (zero line) by the shaft bottom linker again, and return ground electrical power control cabinet, constitute an electrical heating loop.The function of this device is that down-hole oil tube and ground level insulation guarantee that the contained paraffin of viscous crude melts, and makes underground petroleum can successfully be discharged to ground by oil well pump.
Below in conjunction with accompanying drawing planform volt of the present utility model is specified
Accompanying drawing is a structural representation of the present utility model
The special well head 4-of 1-power supply 2-polished rod 3-insulating short section 5-insulation sucker rod 6-insulation centralizer 7-oil pipe 8-sucker rod 9-sleeve pipe 10-oil well pump 11-down-hole linker
The structure of this device is:
Special well head 3 with cable outlet is connected with insulating short section 4, and insulating short section 4 is connected with oil pipe 7. Polished rod 2 inserts in the special well head 3, and its lower end is connected with insulation beam hanger 5, and insulation beam hanger 5 lower ends are connected with beam hanger 8, and oil well pump 10 is arranged at beam hanger 8 bottoms. Oil pipe 7 outer surface covers have insulating centralizer 6, and there is sleeve pipe 9 insulating centralizer 6 outsides. Between device bottom oil pipe 7 and the sleeve pipe 9 linker 11 is arranged. The live wire of power supply (mobile or fixed power source) 1 is received on the oil pipe 7 zero line
Receive on the sleeve pipe 9 through linker 11, form an electrical heating loop. Because heater circuit is arranged, high content of wax viscous crude and viscous crude in the oil pipe are melted, insulating short section is arranged again on the oil pipe, insulation beam hanger and insulating centralizer, therefore when mining operations, down-hole oil tube and ground level insulate, and can successfully crude oil be discharged to ground.
The utility model has the advantages that, compact conformation, insulating properties are reliable, can guarantee that the high content of wax and viscous crude melt smoothly, exploit, and cost is low, and is easy to use.
Embodiment:, can implement according to the relevant explanation processing and manufacturing in the structure of accompanying drawing and the manual.
