Description
The utility model relates to oil exploitation technology, specifically is a kind of thickened oil recovery automatic heating device.
When thickened oil recovery, because viscous crude condensation point height, the crude oil wax adhesive attraction can make with oil-extractor polish-rod down slow, reduce mechanical oil recovery efficient, have a strong impact on oil recovery amount, adopt mechanical removal and the material of oil recovery, human cost are significantly improved, at present to the way that the down-hole steam injection increases the well temperature, the device of a kind of effective heavy crude heat extraction that the oil-field thick-oil individual well is not provided also, this makes the oil recovery production difficulty of viscous crude individual well very big.
The utility model purpose is to overcome the problems referred to above, heats up, improves oil stream temperature, reduces the thickened oil recovery automatic heating device that crude oil is analysed wax and viscosity of crude, reduction oil flow resistance, improved the oil pumper pump efficiency to the down-hole heating crude oil in the face of the oil-field thick-oil individual well provides a kind of.
The utility model is achieved in that
The thickened oil recovery automatic heating device, form by oil pipe 1, sleeve pipe 2, petroleum pipeline 3, heating furnace 4, gs-oil separator 6, strainer 8, flow-limiting valve 9, valve 10, the petroleum pipeline 3 that is communicated with heating furnace 4 is arranged on the oil pipe 1, petroleum pipeline 3 outlets 5 on the heating furnace 4 are communicated with gs-oil separator 6, the outlet 7 of gs-oil separator 6 petroleum pipelines is communicated with sleeve pipe 2 through filter 8, flow-limiting valve 9, valve 10, and the passage 23 that is communicated with casing annulus is arranged in oil pipe 1 down-hole.
The utility model also is achieved by the following scheme:
Valve 11 is housed on petroleum pipeline 3, production trunk line flap valve 12 is housed on gs-oil separator 6.
At heating furnace 4 tops smoke vent opening 14 is housed, pin coil pipe 15 is equipped with in heating furnace 4 inside, and is communicated with petroleum pipeline 3 and gs-oil separator 6, and strong and weak nozzles 16 are housed in the bottom of heating furnace 4, and natural gas line 13 is communicated with it.
The shell upper of heating furnace 4 and bottom have ventilation opening 17.The top is equipped with and is communicated with inner deashing pipe 19.

The utility model description of drawings is as follows:
Fig. 1 is a thickened oil recovery automatic heating device schematic diagram;
Fig. 2 is the heating furnace structure schematic diagram;
Fig. 3 is the heating furnace sectional view;
Fig. 4 is the temperature-controlled circuit schematic diagram.
Describe in detail below in conjunction with accompanying drawing.
The utility model heating furnace 4, oil pipe 1, sleeve pipe 2, pipe network and automatic temperature control device 21 3 parts are formed.The petroleum pipeline 3 that is communicated with heating furnace 4 is arranged on the oil pipe 1, petroleum pipeline 3 outlets 5 on the heating furnace 4 are communicated with gs-oil separator 6, the outlet 7 of gs-oil separator 6 petroleum pipelines is communicated with sleeve pipe 2 through filter 8, flow-limiting valve 9, valve 10, and the passage 23 that is communicated with casing annulus is arranged in oil pipe 1 down-hole.
Heating furnace 4 is by pin coil pipe 15, and the strong and weak nozzles 16 of deashing pipe 19 and natural gas are formed.Deashing pipe 19 is the pipelines with compressed air cleaning burner hearth.When natural gas enters from managing 13, to strong and weak nozzles 16, strong and weak nozzles 16 are little nozzles that a normally open is arranged through electromagnetic valve 18, and the big nozzles that can control quantity combusted are arranged simultaneously.After lighting, the oil well casing 2 two parts interfaces that are subjected to the outer petroleum pipeline 3 of hot coil group 15 and oil well and feed back, constitute closed circuit at down-hole passage 23, power by oil extraction pump, the coil pipe group 15 that the crude oil of all gathering out enters heater heats, and then, portion of hot crude oil is done through gs-oil separator 6 collection inputs, other pyrogen oil make the thick oil underground well heat temperature raising through filter 8, current limit control valve 9 feedback down-holes.This heat cycles of not stopping causes the down-hole viscosity of crude to reduce, and implements heavy crude heat extraction.
Promote at the viscous crude machine under the effect of power, down-hole crude oil is extracted out from oil pipe 1 through 11 outputs of oil pipe 1 outlet valve, enter in the stove along oil pipeline 3, carry out heat temperature raising, heated then crude oil is flowed out by delivery outlet 5 and enters gs-oil separator 6, carry out Oil-gas Separation at this, the input outside the main line flap valve 12 of gs-oil separator upper end of a part of crude oil and gas is done, another part degassed crude enters oil well casing 2 by 7 outputs through filter 8, flow control valve 9, sleeve pipe 2 inlet valves 10.Owing to have action of pressure between sleeve pipe 2 annular spaces and the oil pipe 1, can make pyrogen oil flow to down-hole oil tube entrance 23, again by the power lifting ground of oil pumper, through valve 11 outputs of oil pipe outlet along sleeve pipe, enter heating furnace 4 bodies, formed the closed circuit of a closed loop.Constantly heating and circulation cooperates suitable heating and current limliting to regulate, and sets up the Circulation and Hot Oil Spray of constant-temperature constant-current, thereby realized down-hole heating crude oil heavy crude heat extraction.
