Description
Technical field
The utility model relates to oil-field thick-oils to exploit well head ancillary equipment, in order to solve oil-field thick-oil well crude oil extraction viscosity reduction
The problem of, specifically a kind of unpowered set chemicals dosing plant.
Background technique
Gudong field is developed for many years at present, has entered the " three high " development phase, and the acceleration successively decreased with oil field, viscous crude is opened
Hair has been the important component of crude oil production, and according to statistics, viscous crude well production has accounted for 14.3% at present.In recent years, it was opened in viscous crude
The cold excavating technology of casing dosing viscosity reduction is mostly used to be produced in adopting, the operating method of live heavy oil wells addition thinner is：It is first
First, sleeve gate will be opened, after casing gas is vented, secondly, once pouring into one to two barrel from sleeve valve by thinner.It is above-mentioned
Method has the following disadvantages：First is that can not be difficult to persistently send out according to the condition of production dynamic regulation thinner of oil well, thinner
The effect of waving, action time is short, and oil increasing effect is poor, and causes the waste of thinner；Second is that being discharged directly to the atmosphere natural gas, not only
Natural gas is caused to waste, and serious ground contamination environment；Third is that causing the fluctuation of oil well production pressure difference simultaneously, oil well is being influenced just
Often production, causes sand production, or even cause well of lying when serious.
Summary of the invention
The purpose of this utility model designs a kind of unpowered casing dosing aiming at drawbacks described above of the existing technology
Device.
The utility model is realized by following technical proposals：
The utility model includes：Funnel, dosing valve, safety valve, vent valve, thinner tank, balance pipeline, balanced valve
Door, lower observation valve, flow control valve, dosing pipeline, blow valve, bracket；It is characterized in that：The thinner tank is cylindrical type
Tank body pressure vessel, centre are round tube, and upper/lower terminal is welded as a whole with spherical crown end socket, and top is equipped with safety valve, in safety valve
Be equipped with vent valve on one side, another side is equipped with dosing valve, and the top of dosing valve is equipped with funnel, in the bottom of thinner tank
Centre is equipped with flow control valve, and flow control valve is connect by threeway I with blow valve, dosing pipeline, and dosing pipeline passes through threeway II
It is connected to the top of thinner tank, is equipped with compensation flap in the middle and upper part of dosing pipeline, is laid in the lower part of thinner tank
Valve is observed under three brackets and one, is equipped with upper observation valve on the top of thinner tank.
Thinner can system rated operating pressure in above-mentioned unpowered set chemicals dosing plant is 2.5Mpa.
Working principle：Unpowered set chemicals dosing plant is according to law of connected vessels, by the way of additional thinner tank, by flat
Weigh pipeline connection balance tank body and casing pressure, the thinner in thinner tank under the double action of gravity and casing pressure,
Thinner flows into oil sets annular space by sleeve valve by flow control valve, slowly to the reducing crude oil viscosity in collar-shaped space,
Reduce viscosity of crude, mobility enhancing makes crude oil can smoothly enter into deep well pump, extracts ground out by deep well pump.
The utility model has the beneficial effects that：It is exploited suitable for oil-field thick-oil well, thinner, can by flow control valve
According to the condition of production dynamic regulation thinner of oil well, thinner persistently plays a role, and long action time effectively prevent natural gas
Waste avoids pollution environment, increases oil well crude oil yield, easy to operate, mitigates worker's labor intensity.
Detailed description of the invention

Specific embodiment
The implementation of the utility model is further elaborated with reference to the accompanying drawing：
As shown in Figure 1, unpowered set chemicals dosing plant is by funnel 0, dosing valve 1, safety valve 2, vent valve 3, thinner tank
4, upper observation valve 5, balance pipeline 6, compensation flap 7, lower observation valve 8, flow control valve 9, dosing pipeline 10, blow valve
11, bracket 14 forms；It is characterized in that：The thinner tank 4 be cylindrical type tank body pressure vessel, centre be round tube, upper and lower two
End is welded as a whole with spherical crown end socket, and top is equipped with safety valve 2, is equipped with vent valve 3 on one side in safety valve 2, another side is equipped with
The top of dosing valve 1, dosing valve 1 is equipped with funnel 0, is equipped with flow control valve 9, flow in the bottom center of thinner tank 4
Regulating valve 9 is connect by threeway I with blow valve 11, dosing pipeline 10, and dosing pipeline 10 passes through the upper of threeway II and thinner tank 4
Portion's connection is equipped with compensation flap 7 in the middle and upper part of dosing pipeline 10, is laid with three brackets 14 in the lower part of thinner tank 4
