Abstract
The utility model relates to a portable airtight chemical inlet facility for oil well casing, it consists of: reagent barrel, sealing ring, manual cranking suction pump, quick connector, chemical inlet pipe, oil well casing connecting tube, check valve, flowmeter and pressure gauge, wherein reagent barrel is connected with one end of manual cranking suction pump, sealing ring is located on connecting point, the other side of manual cranking suction pump is connected with chemical inlet pipe with the aid of quick connector, the said chemical inlet tube is connected with oil well casing connecting tube with the aid of quick connector, sealing ring is located on said connecting point, check valve, flowmeter and pressure gauge are located on said oil well casing connecting tube. The beneficialeffects of utility model are: the structure is relatively simple, the facility is easy to dismantle, the production cost is low, the facility is environmentally friendly and effective, the amount andspeed of chemical added could be adjusted, small amount of chemicals could be added continuously for several times, in this way, the chemical inlet effect of oil well is ensured.
Description
One, technical field:
The utility model relates to the airtight chemicals dosing plant of a kind of portable oil well casing.
Two, background technology:
Oil well paraffinication, fouling, corrosion are than distinct issues in the oilfield development process, the method that solves this type of problem at present normally installs and fixes the formula chemicals dosing plant at well head or between recovering the oil, regularly inject wax control, antiscale, anti-corrosion agent to the down-hole through pipe box, though this method can solve oil well paraffinication, fouling, etching problem, the cost of production height; When the sleeve pipe atmospheric pressure is big, must be by the emptying exhaust, ability dosing smoothly, this has caused very big pollution to environment, has also wasted a large amount of natural gases simultaneously.
Three, summary of the invention:
The purpose of this utility model is exactly the defective that exists at prior art, and a kind of simple in structure, the airtight chemicals dosing plant of portable oil well casing that can significantly increase work efficiency is provided.
Its technical scheme is: the airtight chemicals dosing plant of a kind of portable oil well casing, comprise medicament bucket, sealing ring, hand suction pump, snap joint, delivery tube, oil well casing tube connector, ball-and-seat, flow meter, pressure meter, it is characterized in that: the medicament bucket connects hand suction pump one end, the junction is provided with sealing ring, the hand suction pump other end connects delivery tube by snap joint, delivery tube connects the oil well casing tube connector by snap joint, and the oil well casing tube connector is provided with ball-and-seat, flow meter and pressure meter.
Effect of the present utility model is: the utility model is simple in structure, quick detachable, cost is low, the airtight dosing of individual well, environmental protection, environmental protection, efficient height, but free adjustment dosing dosage and speed, and can repeatedly carry out low dose of continuous dosing, guaranteed oil well dosing effect.
Four, description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Five, the specific embodiment:
With reference to accompanying drawing, the utility model, comprise medicament bucket 1, sealing ring 2, hand suction pump 3, snap joint 4, delivery tube 5, oil well casing tube connector 6, ball-and-seat 7, flow meter 8, pressure meter 9, it is characterized in that: medicament bucket 1 connects hand suction pump 3 one ends, the junction is provided with sealing ring 2, hand suction pump 3 other ends connect delivery tube 5 by snap joint 4, delivery tube 5 connects oil well casing tube connector 6 by snap joint 4, and oil well casing tube connector 6 is provided with ball-and-seat 7, flow meter 8 and pressure meter 9.
During use, in the dosing process, operate hand suction pump 3 and extract and form medicament in the medicament bucket 1 out certain power, medicament relies on power to be metered in the oil well casing tube connector 6 by delivery tube 5, flow meter 8, and ball-and-seat 7, pressure meter 9 are used to monitor the casing pressure variation and prevent that the casing pressure height from causing refluence, dose is controlled by hand suction pump 3 rotating speeds, reaching regularly, decide matter, quantitative dosing, finish the medicament interpolation after, dismantle this device, reclaimer is finished once-through operation.
