Description
Technical field
This utility model is related to steel wire and wireline operation ground installation technical field, more particularly to a kind of easy accessibility, fast
Test joint that is prompt and can quickly testing sealing property after re-assemblying.
Background technology
The characteristics of steel wire, wireline operation is band press operation, whether intact quite important seals, usually in operation process,
Needs are taken apart and enter steel wire cable instrument under the well head control device on ground, it is necessary to which Jing often takes well head control device (apart
As be lubricator and preventer junction), often dismounting will have been damaged Jing to rubber seal, as other well heads controls set
Standby (lubricator or preventer) voluntarily detects the effect of sealing property after can not all realizing dismounting, enter to re-assembly under instrument
Afterwards, it is impossible to ensure that sealing property is still intact, potential safety hazard is so there is, therefore test joint is connected on into lubricator and blowout prevention
Device junction often takes position apart as Jing, and test joint carries the gauge pipe string of detection sealing property, so dismantles every time
Only can fast and easily detect whether the sealing property of itself is still intact with a handlance after complete.Test joint is exactly
After the completion of dismounting every time, armrest press pump is suppressed, and by pressure gauge, just can directly judge whether inner sealing performance is intact, reaches
The purpose of safety work.Generally known test joint, is distinguished by internal diameter, have 2.5 ", 3 ", 4 ", 5 ", 6.38 " etc..
Before common steel wire and cable execute-in-place, no test joint, when entering steel wire cable tool string under needs, can only be torn open
Lubricator and preventer junction is opened, after directly reconnecting lubricator and preventer after entering under instrument, work is begun to, is had
It is likely to occur dismounting position sealing ring in unloading process to damage, but operator cannot detects, so need a large amount of manpower things
Power, also loses time to check which position is revealed, and test joint is pressed to save substantial amounts of inspection and test period
Power test, if no test joint, cannot be accurate, efficiently check which link has leakage, if can not be timely
Problematic caulking gum part is changed, is directly operated without test, it is possible to pressure leakages occur, it is impossible to normally made
Industry, it could even be possible to cause security incident.
Original no test joint, enters steel wire cable under needing in well head steel wire operation/wireline operation as illustrated in figures 4-5
When tool string, it is necessary to which Jing often takes well head control device (generally at 2 junction A of lubricator 1 and preventer), Jing apart
Often dismounting will have been damaged to rubber seal, A at will be re-assemblied after entering under instrument, frequently dismantled, it is impossible to correctly judge A
Whether place's sealing property is intact, as other well head control devices (lubricator or preventer) can not be all realized after dismounting voluntarily
The effect of detection sealing property, enters under instrument after re-assemblying, it is impossible to ensure that sealing property is still intact, so there is safety
Hidden danger.
It is above-mentioned to understand, in shaft mouth operation dismount and ensure well head after each dismounting Jing normal in order to fast, convenient and safe
Equipment sealing property is still intact, it is necessary to which prior art operation is further improved, one new examination of necessary increase
Test joint.
