Abstract
The upper inlet of a kind of oil well chemical feeding device, including grug feeding jar, grug feeding jar is connected by pipeline and A valve with the outlet of funnel, and the outlet of grug feeding jar lower end is communicated by B valve with oil well casing, is additionally provided with blow valve on the pipeline before oil well casing import；Medicament is stored in grug feeding jar by funnel and A valve；Before dosing, the B valve of grug feeding jar lower part is closed, opening blow valve bleeds off the excessive gas in oil well casing and on pipeline；After pressure balance, blow valve is closed, the B valve for opening grug feeding jar lower part carries out dosing, and medicament passes through pipeline under the effect of gravity and enters oil well casing, and medicament closing conveying has safe ready, advantage small in size, easy to carry.
Description
Technical field
The utility model relates to oilfield machinery field, in particular to a kind of oil well chemical feeding device.
Background technique
In oil well normal productive process, to prevent oil well fouling caused by various internal and external factors, wall wax deposition and pipeline
Corrosion, it is often necessary to the chemical agents such as antisludging agent, Wax removing agent, corrosion inhibiter be added into well.For example, carrying out oil well pickling
Afterwards, acidification raffinate remaining in pit shaft can cause the sour corrosion of pipeline road system, at this moment just need that corrosion inhibiter is added.
The common method of filling medicament is that the medicament that will pull on well is directly poured into casing by funnel.This dosing side
The shortcomings that method is that gas pressure is larger in casing, it is possible to spray the medicament having been added in casing, cause medicament to lose, very
To safety accident.
Summary of the invention
In order to overcome the defects of the prior art described above, the purpose of this utility model is to provide a kind of oil well chemical feeding device,
Feature easy to operate with deft design, small in size, easy to carry.
In order to achieve the above object, the technical solution of the present invention is:
The upper inlet of a kind of oil well chemical feeding device, including grug feeding jar 2, grug feeding jar 2 passes through pipeline and A valve 3-1 and leakage
The outlet of bucket 1 is connected, and the outlet of 2 lower end of grug feeding jar is communicated by B valve 3-2 with oil well casing 5, before 5 import of oil well casing
Pipeline on be additionally provided with blow valve 4.
The utility model deft design, it is easy to operate, medicine is conveyed by the joint operation of valve, grug feeding jar 2 and connected pipeline
Agent, medicament closing conveying, has safe ready, advantage small in size, easy to carry.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The structural principle of the utility model and working principle are described in detail with reference to the accompanying drawing.
Referring to Fig.1, the upper inlet of a kind of oil well chemical feeding device, including grug feeding jar 2, grug feeding jar 2 passes through pipeline and A valve
3-1 is connected with the outlet of funnel 1, and the outlet of 2 lower end of grug feeding jar is communicated by B valve 3-2 with oil well casing 5, in oil well casing 5
Blow valve 4 is additionally provided on pipeline before import, 4 front end of blow valve has screw thread that can closely connect with oil well casing 5；Other valves
It can joint operation with blow valve 4.
The working principle of the utility model are as follows: medicament is stored in grug feeding jar 2 by funnel 1 and A valve 3-1；In dosing
Before, the B valve 3-2 of 2 lower part of grug feeding jar is closed, opening blow valve 4 bleeds off the excessive gas in oil well casing 5 and on pipeline；Pressure
After dynamic balance, blow valve 4 is closed, the B valve 3-2 for opening 2 lower part of grug feeding jar carries out dosing, and medicament passes through pipe under the effect of gravity
Road enters oil well casing 5, and medicament closing conveying has safe ready, advantage small in size, easy to carry.
