Abstract
The utility model relates to an integrative device of proclaiming oneself of oil well operation pole pipe. The problem that current self-sealing device function singleness, have potential safety hazard, workman intensity of labour are big during the construction is mainly solved. The method is characterized in that: the lower part of the hanger lifting joint (13) is connected with a central rod (12), the central rod (12) is connected with a rod pipe self-sealing rubber core upper pressing ring (6) through a hanger, and the rod pipe self-sealing rubber core upper pressing ring (6) is in threaded connection with the main body (5); the bottom of the inner-rod pipe self-sealing rubber core upper pressure ring (6) of the main body (5) is provided with a self-sealing core (4); the bottom of the central rod (12) is connected with a rod pipe adapter (2), and the side wall of the bottom of the main body (5) is connected with a main body gate valve (1). The oil well operation rod and pipe integrated self-sealing device is wide in application range, eliminates potential safety hazards of overflow generated in operation construction and environmental pollution caused by blowout, improves operation efficiency, reduces operation construction cost, and reduces labor intensity of workers.
Description
Technical field
This utility model is related to a kind of oilfield, specifically a kind of oil well operation rod tube one self-packer.
Background technology
There is the extraction well of sucker rod at present in oil well, be to mitigate and prevent rod and tube partial-wear, arranged using lower centralizer in well
Apply, but sucker rod is using causing roofbolt stepped diameters after centralizer, due to no matching used self-styled, problem of environmental pollution is tight
Weight；Existing oil pipe self-packer can not be applied to some new-type simple wellheads simultaneously, and single function, and extraction well sucker rod is removed
Between to stop the operation control well operating time long, there is safety and environmental protection hidden danger, the high labor intensive of workman.
The content of the invention
Above-mentioned in order to overcome the shortcomings of existing oil well self-packer, this utility model provides a kind of oil well operation rod tube one
Body self-packer, the oil well operation rod tube one self-packer are applied widely, eliminate job execution and produce overflow and blowout
When pollute environment potential safety hazard, improve working performance, reduce job execution cost, alleviate the labor intensity of workman.
The technical solution of the utility model is：A kind of oil well operation rod tube one self-packer, including hanger handling connects
Head, main body, the hanger handling joint bottom are connected with center-pole, and center-pole is by hanger and pressure on rod tube self-sealing rubber core
Ring is connected, and rod tube self-sealing rubber core upper press ring is connected with main body screw；In the main body, rod tube self-sealing rubber core upper press ring bottom is equipped with
Self-sealing core, self-sealing core bottom are equipped with pressure release type rod tube self-sealing rubber core, and lead between pressure release type rod tube self-sealing rubber core and main body
Cross step to fix；The center-pole bottom is connected with rod tube adapter, and bottom part body side wall and is connected with main body slide valve.
This utility model has the advantages that：Due to taking such scheme, as the self-packer is connected with well head
The Space-Work of oil jacket well head inner chamber can not be depended on afterwards, do not have supporting making when solving little simple wellhead intracavity space, operation
The self-styled problem of oil pipe；Due to the elastic telescopic and self-sealing core difference level sealing of the pumping rod self seal fuse of the self-packer
Design, in rod job work progress, smoothly profit rises to realize rod string, centralizer, safety joint and piston
Under, and playing a part of Seal Oil tube space, solve after sucker rod uses centralizer, the shank diameter that causes to pump is straight with centralizer
The ratio difference in footpath is excessive, no matching used pumping rod self seal problem；As the self-packer is constructed in rod tube rountrip
In when there is overflow well kick, can rob in 2 minutes and install well head（Rise including screw rod well and stop between lower beam measure construction）, prevent and eliminate
The potential safety hazard of environment is polluted in sucker rod operation construction when producing overflow and blowout, improve working performance, reduce operation
Construction cost, alleviates the labor intensity of workman.
