An oil production well casing dosing device

Abstract

The invention discloses a drug-dosing device for an oil production well casing and relates to the technical field of oil production engineering. The invention includes a liquid medicine storage tank and an oil production well body. A medicine storage mechanism and a liquid medicine anti-sedimentation mechanism are installed inside the liquid medicine storage box. A circulation pump is fixed on one side of the medicine liquid storage box. The storage tank is connected through the first communication pipe, and the outside of the production well body is equipped with a casing body. The present invention can mix various medicines together more uniformly by setting the medicine storage mechanism, can effectively prevent the medicine that is not fully dissolved from entering the inside of the sleeve body, and can effectively protect the medicine liquid storage tank by setting the medicine liquid anti-sedimentation mechanism. The internal liquid is moved to effectively prevent the liquid inside the liquid medicine storage tank from settling. Through the cooperation of various accessories, the liquid can be evenly sprayed into the inside of the sleeve body, thereby greatly improving the effect of dosing.

Description

technical field [0001] The invention belongs to the technical field of oil production engineering, in particular to a drug-adding device for oil production well casing. Background technique [0002] Some oil wells are waxy and oily, and cannot be produced normally. Some oil wells contain corrosive media that corrode oil well production tools, and some oil wells are severely scaled, causing scale sticking and fouling. In order to eliminate waxing, thick oil, The impact of corrosion and scaling on oil well production requires the use of dosing devices to add wax removers, viscosity reducers, corrosion inhibitors, descaling agents and other chemicals to the casing, but the existing dosing devices cannot effectively A variety of drugs are evenly mixed together, and it is impossible to effectively prevent the incompletely dissolved drugs from entering the inside of the sleeve body. The liquid inside the device is prone to sedimentation, and the liquid cannot be sprayed evenly int...
