Abstract
The utility model relates to a hydraulic plunger wellhead close, quantitative and continuous dosing device, belonging to equipment for oilfields. The device consists of a drug-reserving box, a hydraulic regulating valve and a dosing one-way valve; the bottom outlet of the drug-reserving box is connected with the inlet of the hydraulic regulating valve through a liquid inlet valve, a filter and a pipeline; the outlet pipeline of the hydraulic regulating valve is connected with a wellhead through the dosing one-way valve and a dosing valve; and the top pipeline of the drug-reserving box is connected with the outlet pipeline of the hydraulic regulating valve through an unloading one-way valve. The hydraulic plunger wellhead close, quantitative and continuous dosing device has simple structure, reasonable design and no pressure-casing process, can be mounted at an any position of an oil well, is convenient to construct, operate and overhaul, is unrestricted and can realize the close, quantitative (constant flow) and continuous dosing for a high-pressure oil well; the device can adjust the dosage (flow rate) in real time and is accurate to control the flow rate; the device does not affect various operations of the oil well; the device has no process switching and pressure-release operation when drugs are added, so that the personal injury is avoided, and the device is high in safety reliability, is convenient to repair and maintain and has low operating cost.
Description
Technical field
The utility model belongs to the oil field and uses equipment, particularly relates to a kind of hydraulic plunger well head closed quantitative device for continuously adding medicine into.
Background technology
In the oil gas well mining process,, need to add different medicaments, make the maximization that exploitation is more reasonable, guarantee production efficiency because of the ground condition is different.The medicament of oil gas field use at present has two kinds of forms, and a kind of is solid-state pharmacy, during use, directly throws in the well, lets it oneself dissolve, and this mode of lottery makes the medicament rate of dissolution inhomogeneous, causes the medicament drug effect unbalanced; Another kind is a liquid pharmaceutical, during use, directly pours in the well, causes medicament just to add the big formation waste of fashionable drug effect, and the later stage efficacy of a drug is not enough, does not have the effect of application at all.And above-mentioned dual mode all is after at regular intervals, to drop into medicament again, can not realize continuous dosing, causes the serious waste of medicament, and waste of manpower.
Summary of the invention
The utility model is intended to overcome the deficiency of prior art, and a kind of hydraulic plunger well head closed quantitative device for continuously adding medicine into is provided.
The hydraulic plunger well head closed quantitative device for continuously adding medicine into of the utility model; Be to constitute by explosive box, hydraulic regulation valve and the unidirectional valve of dosing; The outlet at bottom of explosive box is through the inlet of feed liquor valve, strainer, pipeline connection hydraulic regulation valve, and the export pipeline of hydraulic regulation valve is connected with well head through the unidirectional valve of dosing, dosing valve.
As the further improvement of the utility model, pipeline is connected with the export pipeline of hydraulic regulation valve through the unidirectional valve of emptying at the top of explosive box.
As the further improvement of the utility model, dosing valve also the parallel connection relief valve.
The hydraulic plunger well head closed quantitative device for continuously adding medicine into of the utility model, simple in structure, reasonable in design, no casing pressure flow process; Can be installed on any position of oil well; Construction, operation, maintenance are conveniently, and be unrestricted, can realize high pressure oil wells airtight, quantitative (constant current), continuous dosing; Can adjust in real time and add dose (flow), flow-control is accurate; Do not influence the oil well operations; Do not have flow process switching, pressure release operation during dosing, avoid personal injury, security reliability is high, and maintenance maintenance is convenient, and operating cost is low.
Description of drawings
Fig. 1 is the structural representation of the utility model hydraulic plunger well head closed quantitative device for continuously adding medicine into.
The specific embodiment
The hydraulic plunger well head closed quantitative device for continuously adding medicine into of the utility model is to be made up of the unidirectional valve 3 of explosive box 1, hydraulic regulation valve 2 and dosing.The outlet at bottom of explosive box 1 connects the inlet of hydraulic regulation valve 2 through feed liquor valve 4, strainer 5, pipeline, and the export pipeline of hydraulic regulation valve 2 is connected with well head through the unidirectional valve of dosing 3, dosing valve 6, and dosing valve 6 is and parallelly connected relief valve 8.
The top pipeline of explosive box 1 is connected with the export pipeline of hydraulic regulation valve 2 through the unidirectional valve 7 of emptying.
