Description
Technical field
The utility model relates to oil extraction in oil field production technology, specifically a kind of closed dosing dress of manual well mouth of oil well
It sets.
Background technique
Oil well is in oil recovery production process, and due to the influence of the factors such as oil is thick, the content of wax, corrosion, will lead to oil well cannot be just
Often production, so different medicaments will be added into well, the amount that different medicaments needs to be added is different, and adding manner is not yet
Together.The chemicals dosing plant of field application is miscellaneous at present has, useful oil drum repacking, and it is straight that useful funnel opens sleeve gate
Connect in casing plus, dosage control is difficult, have pressure plus does not enter, and bleeds off casing gas dosing and will cause casing gas and is discharged into
Atmosphere pollution environment, threatens to operator.
The chemicals dosing plant of field application is miscellaneous at present has, and useful oil drum repacking is put into casing slowly dosing
, have plenty of the funnel for the transformation that sprays fire extinguisher, open sleeve gate directly in casing plus, dosage control is difficult, there is pressure
Power plus do not enter, bleed off casing gas dosing and will cause casing gas and be discharged into atmosphere pollution environment, threaten to operator.
For above situation, at well mouth of oil well sleeve gate, high pressure line and ball-and-seat is installed, are connected with the device
It connects, feeding opening and ball-and-seat pipeline are connected with pharmacy jar, effect of the driving handle piston in piston rod lever conversion pin
Under move backward, at this moment liquid-inlet ball-and-seat is opened, and the ball-and-seat of liquid outlet ball-and-seat liquid and surge tank is closed, by
It not can enter gas in the elevated pressure gas of surge tank, medicament be drawn into piston cylinder；Handle piston is pulled to connect in piston
