Abstract
The utility model discloses a gas-liquid equilibrium continuing auto-filling device used for oil exploration techniques, such as oil well preservation, scale prevention, demulsification, viscosity reduction, wax prevention or the like in oil industry. The air pressure of the oil well annular tube is fully utilized to achieve the equilibrium inside the agent jar and the continuing precise agent-filling is realized by a flow indicator and a control valve according to the designed agent volume. The gas-liquid equilibrium continuing auto-filling device comprises an agent jar, a control valve, an agent jar bracket and a liquid level indicator. The agent jar is provided with an agent inlet opening and the agent goes through the agent inlet tube line and enters the oil extraction well mouth through the annular tube agent inlet opening. The agent jar is provided with a gas inlet valve which is communicated with an annular tube gas valve through the tube line. The gas-liquid equilibrium continuing auto-filling device is characterized by simple structure, practicality, safety, convenient management and wide application in various oil extraction techniques with the need of agent filling for oil wells.
Description
Technical field
The utility model relates to the automatic device for continuously adding medicine into of the mining equipment of petroleum industry, particularly vapor liquid equilibrium, is used for the oil production technology measure such as anticorrosion, antiscale, breakdown of emulsion, viscosity reduction, wax control of oil well.
Background technology
At the oil recovery scene of petroleum industry,, need to add chemical agent and achieve the above object for oil production technology measures such as anticorrosion, the antiscale of carrying out oil well, breakdown of emulsion, viscosity reduction, wax controls.At present, the principle of the device for continuously adding medicine into of using on the oil well mainly utilizes the medicament self gravitation to realize adding the control of dose, and adds dose and can not accurately control.Because the air pressure of a lot of oil wells is bigger, chemicals dosing plant can be unbalance with sleeve pipe feeding opening pressure, and promptly medicament can be subjected to the pressure generation back pressure phenomenon of sleeve pipe gas, the dosing effect that only depends on the self gravitation of medicament to be difficult to realize ideal.By the chemicals dosing plant of plunger dosing pump continuous dosing,, cause application life short besides, also have problems such as easily stolen, power consumption because the utilization rate of its pump is too high fragile.
Summary of the invention
The purpose of this utility model provides the automatic device for continuously adding medicine into of vapor liquid equilibrium, reaches desirable continuous dosing effect, overcomes the defective of prior art.Increase the effect of the oil production technology measures such as anticorrosion, antiscale, breakdown of emulsion, viscosity reduction, wax control of oil well.
The technical program can reach above-mentioned purpose: the automatic device for continuously adding medicine into of vapor liquid equilibrium, comprise pharmacy jar, control valve, pharmacy jar support and content gauge, pharmacy jar is provided with dosing mouth, soup enters production wellhead by the dosing pipeline from the sleeve pipe feeding opening, and pharmacy jar is provided with admission valve and is communicated with the sleeve pipe air valve by pipeline.
The utility model compared with prior art has following significant advantage: this installs successful lead-in bushing gas, make in the pharmacy jar and form pressure differential with sleeve pipe, the air pressure that makes full use of oil well casing is realized the balance that pharmacy jar is interior, add dose according to design, utilize control valve and flow meter to realize accurately dosing continuously.Control valve is a ball-and-seat, can suppress the backflow of sleeve pipe gas and guarantee normal dosing, has reached continuously reasonably dosing effect, realizes adding the accurate metering of dose.Corresponding safety valve, vent valve, pressure meter are installed on the pharmacy jar, have been guaranteed safety in production.If the pressure in the pharmacy jar surpasses the pressure limit of pharmacy jar, safety valve can start release pressure automatically.This apparatus structure is simple, and is safe and practical, and convenient management can be widely used in the oil production technology measure such as anticorrosion, antiscale, breakdown of emulsion, viscosity reduction, wax control of oil well.
