The technical scheme of the oil production unit includes that the oil production unit is mainly composed of a down-hole circulation system, a wellhead sealing system and a ground thermal power system, wherein the wellhead sealing system comprises a hollow sealing rod and a sealing packing, the down-hole circulation system includes a one-way circulation valve, an oil pump and a hollow oil pumping rod, the one-way circulation valve is arranged on the hollow oil pumping rod, the oil pump is disposed at the end of the hollow oil pumping rod, the ground thermal power system is mainly composed of high pressure rubber hoses, a heating furnace and a high pressure pump, the heating furnace is communicated with the high pressure pump by the high pressure rubber hose, and the high pressure pump is communicated with the hollow oil pumping rod by the high pressure rubber hose. The thermal cycle oil production unit in oil fields has the advantages of realizing well bore paraffin removal and viscosity reduction, even cleaning up bypassed oil and paraffin in well bores of oil wells. Normal oil wells take 2-3 hours by using the thermal cycle oil production unit, which does not need stop oil production, facilitates oil well management, greatly prolonging the production period of oil wells, reducing operational cost of oil wells, and improving production safety.
Description
One, technical field:
The utility model relates to a kind of oil well and adopts device, particularly relates to a kind of oil well thermal cycle extracting device of oil.
Two, 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 have the expense height, uneasy congruence is not enough; High-pressure boiler car well-flushing also is the comparison effective and efficient manner, except cost is higher, be exactly in addition oil well under hollow stem can not carry out well supporting with boiler car.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, provides a kind of operating cost low and safe and reliable oil well thermal cycle extracting device of oil.
Its technical scheme is: mainly be made up of the down-hole circulating system, well head sealing system and ground level heat dynamical system; The well head sealing system comprises hollow stem sealer and sealed packing, and the described down-hole circulating system comprises one-way circulation valve, oil well pump and hollow rod, and hollow rod is provided with one-way circulation valve, and oil well pump is installed in the end of hollow rod; The ground level heat dynamical system mainly is made up of high-pressure rubber pipe, heating furnace and high-pressure pump, and described heating furnace is communicated with high-pressure pump by high-pressure rubber pipe, and high-pressure pump is communicated with hollow rod by high-pressure rubber pipe.
Described one-way circulation valve is installed in the wax deposition of hollow rod and puts following about 30 meters.
The beneficial effects of the utility model are: utilize the thermal source on ground, utilize thermal power system to heat viscosity reduction and wax removal processing for the hollow rod of oil well and the pit shaft of oil well efficiently; Pump into hollow rod for the liquid such as profit of the former well after heating by the circulation pump on ground, open one-way circulation valve in the hollow rod by the pressure of pump, form the circulation of hollow rod and pit shaft, the viscosity reduction and the wax removal of pit shaft have been realized giving, till the dead oil in the well wellbore and wax deposition are cleaned out, normal oil well needs 2-3 hour, neither needing to stop the well influence produces, make things convenient for oil well management again, prolonged the production cycle of oil well greatly, reduce the operating cost of oil well, and improved the safety of producing.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Among the last figure: heating furnace 1, high-pressure rubber pipe 2, high-pressure pump 3, sealed packing 4, hollow stem sealer 5, hollow rod 6, one-way circulation valve 7, oil well pump 8.
Five, the specific embodiment:
In conjunction with the accompanying drawings, the utility model will be further described:
Mainly form by the down-hole circulating system, well head sealing system and ground level heat dynamical system; The well head sealing system comprises hollow stem sealer 5 and sealed packing 4, and the described down-hole circulating system comprises one-way circulation valve 7, oil well pump 8 and hollow rod 6, and hollow rod 6 is provided with one-way circulation valve 7, and oil well pump 8 is installed in the end of hollow rod 6; The ground level heat dynamical system mainly is made up of high-pressure rubber pipe 2, heating furnace 1 and high-pressure pump 3, and described heating furnace 1 is communicated with high-pressure pump 3 by high-pressure rubber pipe 2, and high-pressure pump 3 is communicated with hollow rod 6 by high-pressure rubber pipe.Described one-way circulation valve 7 is installed in the wax deposition of hollow rod 6 and puts following about 30 meters.
According to the oil well paraffinication cycle, hot fluid is after heating, enter hollow rod with high-pressure pump by high-pressure rubber pipe, under certain pressure, the general opening pressure of one-way circulation valve is 0.3Mpa, hot fluid through oil pipe melts wax deposition crude oil, be circulated in the ground level heat jar, circulate through heating, logical until whole circulations, when the import of ground device reached consistent with outlet temperature, well-flushing finished.
With the effective heating of the small part liquid in the well wellbore by ground, improve heat, by the pump on ground it is turned back in the oil well again circulates by hollow rod, effect by heat reaches to the dead oil in the pit shaft and highly coagulates oil and wax deposition is carried out wax removal and viscosity reduction is handled, make viscosity of crude in the pit shaft that to a great extent reduction be arranged, the crystal of wax is also constantly removed, and is easy to flow, make the follow-up energy on stratum continuously outflow and catch up with, do not form obstacle and influence.The individual well back pressure on ground reduces more obvious, has saved a large amount of energy simultaneously.
