Abstract
The utility model relates to an oil extraction device, in particular to a heat circulation oil extraction device. According to the technical scheme, the heat circulation oil extraction device comprises a downhole oil extraction unit and a circulation heating unit. The downhole oil extraction unit comprises a shaft, a sucker rod and an oil well pump, wherein the sucker rod is arranged in the shaft and connected with the oil well pump. The circulation heating unit comprises a heating furnace, a high-pressure circulating pump, a circulating tube and a return tube, wherein the heating furnace is connected with the high-pressure circulating pump. A sealer is arranged between the sucker rod and the shaft. The circulating tube is arranged between the sucker rod and the shaft. The bottom of the circuiting tube is communicated with the shaft. The heating furnace is connected to the top of the circulating tube. The top of the shaft is connected with the high-pressure circulating pump and the heating furnace through the return tube. The heat circulation oil extraction device has the advantages that by the adoption of the heat circulation oil extraction device, viscosity reduction and paraffin removal are achieved, production cannot be influenced since extraction stopping is not needed, oil well management is convenient, the production period of an oil well is greatly prolonged, the operation cost of the oil well is reduced, and the safety of production is improved.
Description
Technical field
The utility model relates to a kind of oil exploitation device, particularly a kind of thermal cycle oil extraction apparatus.
Background technology
At present, oil well viscosity reduction, paraffin removal and control method are more, and electrical heating is the better measure of effective wax removal viscosity reduction, but exist high, the uneasy congruence of expense not enough; High-pressure boiler car well-flushing is also more effective mode, except cost is higher, be exactly in addition oil well under hollow stem can not carry out well supporting with boiler car.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of thermal cycle oil extraction apparatus is provided, and has extended the production cycle of oil well, has reduced the operating cost of oil well.
Its technical scheme is: comprise down-hole oil production unit, circulating-heating unit, down-hole oil production unit comprises pit shaft, sucker rod, oil well pump, pit shaft inside is provided with sucker rod, sucker rod connects oil well pump, circulating-heating unit comprises heating furnace, high-pressure circulation pump, circulation pipe, return duct, heating furnace connects high-pressure circulation pump, between described sucker rod and pit shaft, be provided with sealer, between described sucker rod and pit shaft, be provided with circulation pipe, circulation pipe bottom is communicated with pit shaft, the top of circulation pipe connects heating furnace, pit shaft top connects high-pressure circulation pump and heating furnace by return duct.
The beneficial effects of the utility model are: by the viscosity reduction and the wax removal that use this device to realize, neither need to stop well impact and produce, facilitate again oil well management, extended greatly the production cycle of oil well, reduce the operating cost of oil well, and improved the safety of producing.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
In upper figure: heating furnace 1, high-pressure circulation pump 2, pit shaft 3, sucker rod 4, oil well pump 5, circulation pipe 6, return duct 7, circulation pipe 8.
The specific embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises down-hole oil production unit, circulating-heating unit, down-hole oil production unit comprises pit shaft 3, sucker rod 4, oil well pump 5, pit shaft 3 inside are provided with sucker rod 4, sucker rod 4 connects oil well pump 5, circulating-heating unit comprises heating furnace 1, high-pressure circulation pump 2, circulation pipe 6, return duct 7, heating furnace 1 connects high-pressure circulation pump 2, between described sucker rod 4 and pit shaft 3, be provided with sealer 8, between described sucker rod 4 and pit shaft 3, be provided with circulation pipe 8, circulation pipe 8 bottoms are communicated with pit shaft 3, the top of circulation pipe 8 connects heating furnace 1, pit shaft 3 tops connect high-pressure circulation pump 2 and heating furnace 1 by return duct 7.
Viscosity reduction and the wax removal in this device course of work, realized, neither need to stop well impact and produce, and facilitates again oil well management, extended greatly the production cycle of oil well, reduced the operating cost of oil well, and improved the safety of producing.
