Characteristics are: the container is inside and be equipped with water retaining device by the test chamber somatic part, and water retaining device comprises swing pipe, baffle and nut. Processing has the air vent on the swing pipe, and the baffle leaves the clearance with the vessel inner wall. The utility model discloses super high pressure vessel has add the manger plate function on the basis of original function, in airtight testing process, utilize water retaining device's baffle and the air vent on the swing pipe to keep off the liquid that high pressure splashes in super high pressure vessel, and it is internal by test chamber to have avoided liquid to get into effectively, has satisfied the requirement of airtight test, and this container has compact structure, opens the convenience, reliability height, advantage with low costs. Through the utility model discloses the reliability of airtight test has been ensured.
Description
Technical field
This utility model relates to a kind of ultrahigh pressure vessel, particularly relates to a kind of hermetic seal test ultrahigh pressure vessel.
Background technology
In oil, gas extraction field, difference due to geological conditions, drilling depth is also different, most of oil wells or gas well already more than the 5000m degree of depth, this brings bigger difficulty to drilling well, in order to improve drilling well oil yield further, fracturing technique is just progressively developed and has been applied in modern drilling operation.The fracturing work of oil well is needed significantly high pressure, also the sealing of drilling tool is had higher requirement simultaneously.
At oil, in gas drilling, the drill string thread joint of drilling well to be carried out test force value and need to reach more than 100MPa air tightness test, drillng operation just can be carried out after reaching hermetic seal requirement, so generally provided the pressure of more than 100MPa in hermetic seal test chamber by ultrahigh pressure vessel, in ultrahigh pressure vessel, medium is generally the mixture of water and gas, when utilizing hydraulic booster to make the mixing gas in ultrahigh pressure vessel reach the force value specified, the drill string thread joint of drilling well is carried out air tightness test, at present under supertension state, have internal tank separatory cognition and be splashed in tested cavity, make air-leakage test unstable, even test product is caused damage, it is difficult to ensure that the accuracy of test and the problem of reliability.
Utility model content:
The purpose of this utility model is in that improving prior art exists circumscribed problem, there is provided a kind of drill string thread joint meeting drilling well that detection extra-high can be allowed in pneumatic sealing test steadily to enter in test chamber, and liquid is not splashed in tested cavity, guarantee accuracy, reliability that hermetic seal tests, it is to avoid liquid enters in tested cavity the hurtful hermetic seal test ultrahigh pressure vessel of test product.
Technical solution:
Hermetic seal test ultrahigh pressure vessel, including: vessel, it is provided with baffle device for water in described vessel, described baffle device for water includes: swing pipe, baffle plate, described swing pipe one end is fixing with baffle plate to be connected, the other end is connected with the tested cavity of hermetic seal by the air inlet/outlet on vessel, and described swing pipe is provided with passage, is provided with the gap that gas passes through between baffle plate and vessel inwall.
Described vessel straight barrel, straight barrel is respectively arranged at two ends with closure, one end closure has air inlet/outlet, is connected with swing pipe top bottom air inlet/outlet, and other end closure has liquid in-out mouth.
Described vessel is threadeded with closure, and is sealed by black box.
Described closure adopts overall structure or split-type structural, and overall structure includes: plug screw；Split-type structural includes: swivel nut, cock body.
Described black box adopts metal triangular pad and packing ring combination to seal or double seal ring seals.
Being installed with nut on described baffle plate, swing pipe one end is threaded with baffle plate by nut or welds.Container inlet is connected with pump.
This utility model container is namely on the basis of ultrahigh pressure vessel original function, it is additionally arranged water retaining function, hydraulic booster makes the mixing gas in ultrahigh pressure vessel reach pneumatic sealing test required value, detected gas is in entering tested cavity process, partially liq will can be splashed in tested cavity at elevated pressures, the most of liquid splashed is kept off in ultrahigh pressure vessel by the baffle plate first with baffle device for water, with the extra-high of few partially liq again through the passage having on swing pipe, then in tested cavity.Efficiently avoid liquid and enter the accuracy affecting pneumatic sealing test in tested cavity.This container has compact conformation, unlatching is convenient, reliability is high, cost is low, both can be applicable to each big probing place such as ocean, land, it is possible to for detection test mechanism, the advantage that range of application is comparatively wide simultaneously.

Detailed description of the invention
On this utility model vessel 1, lower two-port is respectively provided with closure 2, closure 2 adopts swivel nut and cock body or plug screw, on, equipped with black box 3 in lower closure 2, black box 3 adopts double, two O type sealing ring or metal triangular pad and O type packing ring combination to seal structure, the lower center hole portion of upper end closure 2 is equipped with baffle device for water 4, baffle device for water 4 is by swing pipe 5, baffle plate 6 and nut 7 form, centre bore portion, swing pipe 5 top and bottom adopts engagement thread to connect, swing pipe 5 lower end is connected with adopting engagement thread in nut 7 hole, swing pipe 5 offers passage 8, baffle plate 6 is fixing with nut 7 to be connected, baffle plate 6 and vessel 1 inwall leave the gap of 1mm to 3mm, the air inlet/outlet 9 of vessel 1 upper port is connected with tested cavity, the liquid in-out mouth 10 of vessel 1 lower port is connected with high-pressure pump.
During work, high-pressure pump makes the mixing gas in ultrahigh pressure vessel reach pneumatic sealing test required value, detected gas is in entering tested cavity process, partially liq will can be splashed in tested cavity at elevated pressures, the most of liquid splashed is kept off in ultrahigh pressure vessel by the baffle plate first with baffle device for water, with the extra-high of few partially liq again through the passage having different azimuth on swing pipe, then in tested cavity.Efficiently avoid liquid entrance in tested cavity, test product to be caused damage, it is ensured that the reliability of hermetic seal test, accuracy.This container has compact conformation, unlatching is convenient, detection reliability is high, cost is low, the advantage of applied range.
