Description
Technical field
This utility model is related to the design field of oil extraction in oil field well-flushing device.
Background technology
In long-term oil recovery process, contained Colophonium class and waxiness composition in Produced Liquid, on the ground of pit shaft near its circumference
Assemble in layer, block formation influence well oil output.For guaranteeing normal oil recovery, crude oil stable high yield is realized, it is necessary to periodically to adopting
Oil well is cleaned.During conventional oil well well-flushing, using cementing truck hot water well-flushing, easily cause oil layer pollution, discharge opeing phase length, do not return
The problems such as liquid, not high quality of heat washing, it is impossible to efficiently accomplish paraffin removal from oil well task.
Utility model content
This utility model purpose is that for a kind of small volume and less weight of problem above offer, using effect is good, install maintenance side
Just oil well spontaneous circulation well washing apparatus.
This utility model includes that oil pumper, production tree, digital mass flowmeter calculate instrument, chemicals dosing plant and electric heater unit；
The oil pumper is connected with production tree, and the production tree outlet is connected with the input of electric heater unit by feed tube, described
The outfan of electric heater unit is connected with Christmas tree casing by drain pipe；Be respectively provided with the electric heater unit two it is warm
Control device and a thermometer intubation, arrange sewage draining valve in the electric heater unit bottom；The chemicals dosing plant is connected to out liquid
Guan Shang；The digital mass flowmeter is calculated instrument and is connected with two temperature controllers respectively.
Advantage of the present utility model has：1）Small volume and less weight, the widely applicable oilwell produced fluid amount that can be used for is between 5t/d-15t/d
Thermal well flushing, well-flushing are capable of achieving the work of oil well dosing wax removal simultaneously.2）Avoid the oil reservoir that traditional cements car hot water well-flushing is caused
Pollution, discharge opeing phase length, do not return liquid, the problems such as quality of heat washing is not high.3）It is reasonable in design, function admirable, reliable operation, service life
Grow, be easily installed maintenance.4）Production metering of oil wells error school can be carried out as a kind of measuring equipment, to onsite application indicator
Test.5）Working procedure is simplified, oil well production efficiency is improved, has been saved well-flushing cost.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
As shown in figure 1, calculating instrument 3, chemicals dosing plant 4 and electrical heating dress including oil pumper 1, production tree 2, digital mass flowmeter
Put 5；Oil pumper 1 is connected with production tree 2, and the outlet of production tree 2 is connected with the input of electric heater unit 5 by feed tube 6, and electricity adds
The outfan of thermal 5 is telescopic joint with production tree 2 by drain pipe 7；Two temperature controllers are respectively provided with electric heater unit 5
8 and a thermometer intubation 9, in 5 bottom of electric heater unit, sewage draining valve 10 is set；Chemicals dosing plant 4 is connected on drain pipe 7；
Digital mass flowmeter is calculated instrument 3 and is connected with two temperature controllers 8.
