Abstract
The utility model relates to a well head charge device, especially gravity type constant current oil well charge device in the oil recovery field. Gravity type constant current oil well charge device including the box, sets up medicine storage tank and adds the medicinal cupping in the box, the medicine storage tank top sets up the atmospheric valve, and medicine storage tank bottom and add the medicinal cupping and pass through the pipe connection sets up the solenoid valve on the pipeline, sets up floating ball liquid level switch in adding the medicinal cupping, and floating ball liquid level switch connects the solenoid valve, adds medicine tank bottom end and sets up and add the pencil, with setting up the stop valve on the pencil. The utility model discloses simple structure, convenient operation, long service life utilizes gravity to add the medicine, and the expense is low, adds the medicinal cupping through the setting and as transfer mechanism, has avoided the liquid medicine velocity of flow to change along with liquid level's change, reduces the fluctuation of liquid medicine addition, realizes that the constant current adds the medicine.
Description
Technical field
The utility model relates to a kind of wellhead chemicals-feeder in oil recovery field, particularly gravity constant current oil well chemical feeding device.
Background technology
In oilfield development process, along with the reduction of temperature and pressure and the precipitation of gas, the solvability of crude oil leaf wax can decline to some extent, cause oil well paraffinication, address these problems, chemical agent will be added in oil well, to ensure that oil well is normally produced, current oil well dosing mainly adopts artificial sleeve pipe to fill with and well head continuity point drips Teat pipette, once property dosing filled with by artificial sleeve pipe can not play the shortcomings such as drug effect, efficiency is low, labor strength is large continuously, well head continuity point drips Teat pipette to be had costly, the shortcomings such as application life is short.
Summary of the invention
The purpose of this utility model is to provide the gravity constant current oil well chemical feeding device that a kind of structure is simple, long service life, expense are low, can realize constant current dosing.
The technical solution of the utility model is:
Gravity constant current oil well chemical feeding device, comprise casing, medicine storing pot and grug feeding jar are set in casing, medicine storing pot top installation of relief valve, is connected by pipeline with grug feeding jar bottom medicine storing pot, pipeline arranges electromagnetic valve, in grug feeding jar, floating-ball level switch is set, floating-ball level switch connected electromagnetic valve, grug feeding jar bottom arranges chemical feed pipe, and chemical feed pipe arranges stop valve.
Described floating-ball level switch comprises ball float and guide rod, and ball float can move up and down along guide rod, guide rod is arranged high fluid level markings and low fluid level markings.
Described grug feeding jar top is communicated with communicating pipe, pipeline bottom medicine storing pot and between grug feeding jar arranges dosing pump, dosing pump connects floating-ball level switch, and by realizing the pressure balance between grug feeding jar and sleeve pipe communicating pipe, medicament realizes even dosing under the effect of intelligent management.
The beneficial effects of the utility model are: structure is simple, easy to operate, long service life, utilize gravity dosing, expense is low, by arranging grug feeding jar as transfer mechanism, avoid liquid flow velocity to change with the change of liquid level, reduce the fluctuation of liquid addition, realize constant current dosing.
