Abstract
The invention relates to the technical field of oil field exploitation, in particular to a dosing and metering device for a shaft mouth.The dosing and metering device comprises an adjusting valve, a stop valve, a blowoff valve, a funnel, a sewage discharge outlet, a sleeve, a medicament storage tank and a labeling column. The adjusting valve, the labeling column and the stop valve are connected in series with the bottom of the medicament storage tank in sequence. The stop valve is connected with the upper end of the medication storage tank connected with the funnel for a dosing port. The sleeve is communicated with the stop valve. The bottom of the medicament storage tank is communicated with the sewage discharge outlet via the blowoff valve.The dosing and metering device for the shaft mouth has following beneficial effects: long-term and stably continuous addition of medicament is achieved; medicament concentration of an output liquid medium is stably controlled so that the best medicament-adding effect is obtained; automatic dosing technology and self-control technology are adopted by the shaft mouth so that the problem that an antisludging agent and a corrosion inhibiter are hard to prepare on the site is solved; and requirements for timing, quantification and continuous medication addition of chemical agents are satisfied.
Description
Technical field
The present invention relates to oil field development technical field, be specifically related to a kind of oil field shaft mouth dosing metering device.
Background technology
At present; Ordos Basin major part oil field also exists moisture height; downhole tubular and roofbolt fouling corrosion are serious, and the exploitation of some difficult-to-produce reserves and some oil wells are because of reasons such as oily thick and wax deposition, cause oil well production abnormal or wellhead back pressure is high and collects the problems such as defeated difficulty.
Solve these problems it is necessary to add chemical agent in oil well, to ensure that oil well normally produces. On-the-spot commonly used artificial dosing method existing defects: disposable dosing can not play drug effect continuously; Well head is without measuring equipment, it is impossible to ensure chemical feeding quantity; Well head dilutes facility without water mixing, and medicament wall built-up is serious, it is impossible to all arrive at shaft bottom; Labor strength is big. And electric pressuring pump dosing utilizes the reciprocating motion of polished rod to drive thromboembolism pump continuous small dose dosing, its advantage is that medicinal liquid can be continuously added into oil sets annular space, and medicinal liquid utilizes fully; Shortcoming is that life-span of pump is shorter, maintenance is complicated, costly, and the individual part of tube rod pump can not total enclosing protection, be easily destroyed.
Summary of the invention
It is contemplated that propose a kind of well head Automatic Dosing metering device.
Technical program of the present invention lies in:
Well head medicine-adding metering device, by regulating valve, stop valve, blowoff valve, funnel, sewage draining exit, sleeve pipe, medicine storing pot, Calibration Column forms; Wherein, regulate valve, Calibration Column and stop valve and be sequentially connected in series bottom medicine storing pot; Stop valve, stop valve are connected with medicine storing pot upper end; Medicine storing pot connects dosing mouth funnel, and sleeve pipe connects with stop valve; The bottom of medicine storing pot is connected with sewage draining exit by blowoff valve.
Preferably, described medicine storing pot upper end is provided with emptying relief valve and manometer.
It is highly preferred that be provided with electric tracing inside described medicine storing pot, electrically heat tracing switch is arranged on the shell of medicine storing pot.
It is highly preferred that described medicine storing pot shell is additionally provided with liquidometer and thermometer.
Or preferably, described medicine storing pot upper end connects dosing mouth funnel by stop valve.
Or preferably, the pipeline of described sleeve pipe and stop valve is by the pipeline connection between stop valve and Calibration Column and stop valve.
The method have technical effect that:
Present invention achieves long-term, the steady and continuous of medicament to add, it is possible to stably control the drug concentration in production fluid medium, it is achieved best dosing effect. Well head Automatic Dosing technology adopts automatic control technology, solves antisludging agent and the big problem of corrosion inhibiter extemporaneous preparation difficulty, it is achieved that the timing of chemical agent well head, quantitatively, the requirement of continuous dosing. Mounting process of the present invention is simple, adopts rustless steel to process, less costly, repeatable installs between different oil wells, dismounting, install, easy to carry, saved equipment and materials, it is possible to popularization and application widely.

Wherein, 1-regulates valve; 2-stop valve; 3-blowoff valve; 4-emptying relief valve; 5-manometer; 6-liquidometer; 7-thermometer; 8-funnel; 9-sewage draining exit; 10-sleeve pipe; 11-medicine storing pot; 12-electric tracing.
Detailed description of the invention
Well head medicine-adding metering device, by regulating valve 1, stop valve 2, blowoff valve 3, funnel 8, sewage draining exit 9, sleeve pipe 10, medicine storing pot 11, Calibration Column 13 forms; Wherein, regulate valve 1, Calibration Column 15 and stop valve 2-2 and be sequentially connected in series bottom medicine storing pot 11; Stop valve 2-3, stop valve 2-4 are connected with medicine storing pot 11 upper end; Medicine storing pot 11 upper end connects dosing mouth funnel 8 by stop valve 2-5, and the pipeline of described sleeve pipe 10 and stop valve 2-3 is by the pipeline connection between stop valve 2-1 and Calibration Column 13 and stop valve 2-2; The bottom of medicine storing pot 11 is connected with sewage draining exit 9 by blowoff valve 3. Described medicine storing pot 11 upper end is provided with emptying relief valve 4 and manometer 5. Inside is provided with electric tracing 12, and the switch of electric tracing 12 is arranged on the shell of medicine storing pot 11. Shell is additionally provided with liquidometer 6 and thermometer 7.
First manual-lock regulates valve 1, stop valve 2-1, stop valve 2-2, blowoff valve 3, the medicament prepared is added in medicine storing pot 10 by dosing mouth funnel 8, close stop valve 2-4 afterwards, stop valve 2-5, open stop valve 2-3, owing to sleeve pipe 10 has pressure, the pressure of several seconds rear sleeves 10 and medicine storing pot 11 reaches balance, open stop valve 2-2 again, medicament flows in Calibration Column 13 under gravity, after Calibration Column 13 is full of medicament, close stop valve 2-2, open stop valve 2-1 simultaneously, sleeve pipe 10 and Calibration Column 13 form again pressure balance, the flow velocity controlling to flow into sleeve pipe 10 pharmaceutical quantities by controlling to adjust the aperture of valve 1 reaches requirement, the aperture of adjustment valve 1 is closed stop valve 2-1, is opened stop valve 2-2 after regulating, medicine storing pot 11 and sleeve pipe 10 form a pressure balancing system closed again, the medicament of medicine storing pot 11 under gravity, by the accurate calibration of Calibration Column 13, it is achieved accurate measurement continuous dosing.
In use, when ambient temperature is on the low side, thermometer 7 provides alarm signal, starts the switch of electric tracing 12, it is achieved the heating of medicinal liquid, and when medicinal liquid is heated to predetermined temperature, the switch cutting out electric tracing 12 stops heating. So circulation, makes medicinal liquid remain under good environment, and what be beneficial to medicinal liquid fills and give full play to its drug effect smoothly, it is achieved task of heating continuously.
