Description
Technical field
The present invention relates to oil well auxiliary device field more particularly to a kind of underground medicine-adding bins.
Background technique
When carrying out oil exploitation, oil well paraffinication, fouling, corrosion are problems more prominent in oilfield development process, at present
The method for solving problems is usually that fixed chemicals dosing plant is installed between well head or oil recovery, is periodically infused through pipe sleeve to underground
Enter wax control, antiscale, anti-corrosion agent, although this method is able to solve oil well paraffinication, fouling, etching problem, but production cost
It is high；When casing atmospheric pressure is larger, it is necessary to be vented by emptying, the smooth dosing of ability, this causes very big pollution to environment, together
When waste a large amount of natural gas.
Summary of the invention
In view of the foregoing drawbacks or insufficient, the purpose of the present invention is to provide a kind of underground medicine-adding bins.
The technical solution of the present invention is as follows:
Including medicament barrel, sealing ring, sucking pump, quick coupling, delivery tube, oil well casing connecting tube, medicament barrel connection is hand
Suction pump one end, junction are equipped with sealing ring, and the hand suction pump other end connects delivery tube by quick coupling, and delivery tube passes through
Quick coupling connects oil well casing connecting tube, is provided in the oil well casing connecting tube fixed for being sealed with oil well
Buckle.
The oil well casing connecting tube is equipped with ball-and-seat.
The oil well casing connecting tube that is equipped with is equipped with flowmeter and pressure gauge.
The invention has the benefit that
It is the configuration of the present invention is simple, quick detachable, at low cost, the closed dosing of individual well, environmental protection, environmental protection, high-efficient, it can freely adjust
Dosing dosage and speed, and low dose of continuous dosing can be repeatedly carried out, it ensure that oil well dosing effect.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
The present invention will be described in detail with reference to the accompanying drawing.
As shown in Figure 1, the present invention provides a kind of underground medicine-adding bin, including medicament barrel 1, sealing ring 2, sucking pump 3, fast quick access
First 4, delivery tube 5, oil well casing connecting tube 6, medicament barrel 1 connect hand 3 one end of suction pump, and junction is equipped with sealing ring 2, hand
3 other end of suction pump connects delivery tube 5 by quick coupling 4, and delivery tube 5 connects oil well casing connecting tube by quick coupling 4
6, it is provided with for being sealed fixed buckle with oil well in the oil well casing connecting tube 6.Wherein, the oil well casing connects
Adapter tube 6 is equipped with ball-and-seat 7.The oil well casing connecting tube 6 that is equipped with is equipped with flowmeter 8 and pressure gauge 9.
In use, installing oil well casing connecting tube 6 during dosing, sucking pump 3 is operated, medicament in medicament barrel 1 is taken out
Out and certain power being formed, medicament is entered in oil well casing connecting tube 6 by power by delivery tube 5, the metering of flowmeter 8,
Ball-and-seat 7, pressure gauge 9 for monitor casing pressure variation and prevent casing pressure height from causing to flow backwards, dose by hand 3 revolving speed of suction pump come
Control after completing medicament addition, dismantles the present apparatus, reclaimer completes primary behaviour to reach timing, determine matter, quantitative dosing
Make.
