Abstract
The utility model relates to a chemical agent storage slow releasing device in an oil wellbore, which comprises an agent tube containing chemical agent, wherein one end of the agent is provided with a release short section. The utility model further comprises a pore channel and a fixing device, wherein the fixing device is an oil pipe coupling, and the pore channel is provided on the release short section. When in use, the utility model can control the release time and amount of chemical agent, reduce the corrosion on the wellbore and obtain significant economic benefit, having wide application for the oil production of an oil extraction machine.
Description
Technical field:
The utility model relates to a kind of medicament storage releasing device, is the slow releasing device of chemical medicament storage in a kind of well wellbore specifically.
Background technology
Oil well in process of production, therefore burn into wax deposition and scale formation often take place in the steel pipe inwall of oil recovery passage, just need throw in and store a certain amount of chemical agent that is used to prevent burn into wax deposition and fouling in pit shaft.Owing to aqueous chemical medicament very difficult storage in well at present, period of validity is very short, therefore generally uses the Solid-state Chemistry medicament delivery and is stored in the down-hole.At present the method that adopts is only the down-hole is directly thrown in and be stored in to the Solid-state Chemistry medicament, waits for that it dissolves naturally, prevents pipe corrosion, wax deposition and fouling, and such technical scheme is unfavorable for the control in people's the manufacturing process, and effect is also bad.
Summary of the invention
The technical problems to be solved in the utility model is that the input of existing medicament is wayward and effect is bad, thereby provides a kind of device to be used for throwing in chemical agent, is beneficial to manufacturing process is controlled, and reaches a kind of reasonable antiseptic effect.
In order to solve the problems of the technologies described above, the utility model provides the slow releasing device of chemical medicament storage in a kind of well wellbore, this device is provided with the powder charge pipe, chemical agent is equipped with in powder charge pipe inside, powder charge Guan Yiduan also is provided with and lets out the medicine pipe nipple, this device also is provided with duct and fastening devices, and described fastening devices is tubing coupling, and described duct is located at and is let out on the medicine pipe nipple.
The chemical agent that is equipped with in the powder charge pipe is preferably solid state, is preferably Powdered or graininess.Further preferred version is: tubing coupling is provided with dead stifled pipe nipple, lets out and also is provided with the plug joint on the medicine pipe nipple; Between tubing coupling, extremely stifled pipe nipple and the powder charge pipe and the powder charge pipe, let out that connected mode is screwed connection between medicine pipe nipple and the plug joint.
This device is provided with the duct, is beneficial to that crude oil flows into and flows out, and dissolves and release medicine, and the size that the rate of release of chemical agent also can passing hole channel is regulated simultaneously, therefore can reach antiseptic effect preferably.When adopting said apparatus to carry out operation, the powder charge pipe is provided with fastening devices, can realize that the powder charge pipe is connected with oil pipe.When sucker rod is up and down, oil from around ooze out, enter oil pipe, the utility model device is in the bottom, is soaked by oil.The mobile of oil impels the medicament in this utility model slowly to be dissolved from the duct outflow, and the chemical composition of corroding with causing in the oil reacts, and reaches prevention effect.Use this device, can make the release time and the burst size of this chemical agent more reasonable, obviously reduce the well wellbore extent of corrosion, increase medicament storage and service time, prolong oil well repair free period greatly, reduce operating cost, the corrosion of oil pipe and sucker rod is eased simultaneously, also can obtain considerable economic.
Further in the preferred version, plug joint and tubing coupling can be unlikely the leakage chemical agent with the upper and lower side complete closed of this device.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
In the accompanying drawing, 1. tubing coupling, 2. dead stifled pipe nipple, 3. powder charge pipe, 4. chemical agent is 5. let out the medicine pipe nipple, 6. the plug joint.
The specific embodiment
In the well wellbore shown in this Figure of description in the slow releasing device of chemical medicament storage, tubing coupling (1), extremely stifled pipe nipple (2), powder charge pipe (3), let out medicine pipe nipple (5) and plug joint (6) is linked in sequence together, tubing coupling (1), extremely block up between pipe nipple (2) and the powder charge pipe (3) and powder charge pipe (3), let out that connected mode is screwed connection between medicine pipe nipple (5) and the plug joint (6).Chemical agent (4) is housed in the powder charge pipe (3).Tubing coupling (1) is connected with oil pipe, connects oil pipe on oil well pump and the pump on it, is sucker rod topmost then, is extracting device of oil of the prior art with top again, thus integrant oil production machine.
During operation, with plug joint (6), from bottom to top screwed connection is together successively to let out medicine pipe nipple (5), powder charge pipe (3), use the tractor hoist G.I.H, in powder charge pipe (3), pour selected powdery or the granular chemical agent (4) that is used for pre-anticorrosion (fouling or wax deposition) then into, connect dead stifled pipe nipple (2) and tubing coupling (1) then, again oil pipe on afterbody oil pipe, oil well pump and the pump of completion flow string is arrived projected depth down, be lowered to sucker rod at last.After oil well is opened and is taken out, chemical agent (4) in the powder charge pipe (3) flows out and enters in the oil stream by the dissolving of oil stream and by letting out duct that medicine pipe nipple (5) is provided with at afterbody, react with the chemical composition that causes corrosion (fouling or wax deposition), corrosion (fouling or wax deposition) degree by the oil stream after chemical agent (4) processing reduces, and therefore reaches the effect of control.The utility model can be widely used in the oil field oil production machine and carry out oil producing operation.
