The technical problems to be solved in the utility model is to provide a kind of super-pressure stable-pressure device, the arrangement achieves the pressure increment that can balance charge explodes and produce in superhigh-pressure high-temp container instantaneously, the pressure decrement caused because perforating gun cavity is filled up by medium after charge explodes can be made up simultaneously, reduce ultrahigh pressure vessel design pressure, reduce vessel fabrication cost, simple and practical, high voltage performance is good, long working life.Overcome existing charge explodes and in superhigh-pressure high-temp container, produce pressure increment instantaneously, be difficult to the deficiency of this part pressure increment of counteract.
Technical solution adopted in the utility model is: a kind of super-pressure stable-pressure device, comprises super-pressure vacuum tank; Super-pressure vacuum tank comprises cylindrical shell, cylindrical shell upper end inwall connects upper threaded pressure ring, upper threaded pressure ring pushes down seal head, cylindrical shell lower end inner wall connects lower threaded pressure ring, and lower threaded pressure ring pushes down lower seal head, and upper seal head, lower seal head center all have passage, upper seal head, lower seal head outer wall are all sealed by sealing ring and cylinder inboard wall, inner barrel is provided with piston, and sealing between piston and cylinder inboard wall also can move up and down along cylindrical shell, and cylinder body outer wall is connected with supporting leg; Upper seal head central passage connects demolition set and nitrogen pipeline electromagnetic valve respectively by pipeline, pipeline between super-pressure vacuum tank and nitrogen pipeline electromagnetic valve is installed gas-phase space pressure sensor, nitrogen pipeline electromagnetic valve is connected with high pressure nitrogen pipeline, lower seal head central passage connects liquid phase pipeline electromagnetic valve by pipeline, pipeline between super-pressure vacuum tank and liquid phase pipeline electromagnetic valve is installed liquid Space pressure sensor, liquid phase pipeline electromagnetic valve connects ultrahigh pressure vessel by pipeline.
The beneficial effects of the utility model are: the utility model can balance the pressure increment that charge explodes produces instantaneously in superhigh-pressure high-temp container, the pressure decrement caused because perforating gun cavity is filled up by medium after charge explodes can be made up simultaneously, reduce ultrahigh pressure vessel design pressure, reduce vessel fabrication cost, simple and practical, high voltage performance is good, long working life.
Accompanying drawing illustrates:
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of super-pressure vacuum tank.
Detailed description of the invention:
As shown in Figure 1 and Figure 2, a kind of super-pressure stable-pressure device, comprises super-pressure vacuum tank 3; Super-pressure vacuum tank 3 comprises cylindrical shell 10, cylindrical shell 10 upper end inwall connects upper threaded pressure ring 5, upper threaded pressure ring 5 pushes down seal head 6, cylindrical shell 10 lower end inner wall connects lower threaded pressure ring 12, lower threaded pressure ring 12 pushes down lower seal head 11, upper seal head 6, lower seal head 11 center all have passage, upper seal head 6, lower seal head 11 outer wall are all by sealing ring 7 and cylindrical shell 10 inner wall sealing, cylindrical shell 10 inside is provided with piston 8, seal between piston 8 and cylindrical shell 10 inwall and can move up and down along cylindrical shell 10, cylindrical shell 10 outer wall is connected with supporting leg 9; Upper seal head 6 central passage connects demolition set 2 and nitrogen pipeline electromagnetic valve 1 respectively by pipeline, pipeline between super-pressure vacuum tank 3 and nitrogen pipeline electromagnetic valve 1 is installed gas-phase space pressure sensor 13, nitrogen pipeline electromagnetic valve 1 is connected with high pressure nitrogen pipeline, lower seal head 11 central passage connects liquid phase pipeline electromagnetic valve 4 by pipeline, pipeline between super-pressure vacuum tank 3 and liquid phase pipeline electromagnetic valve 4 is installed liquid Space pressure sensor 14, liquid phase pipeline electromagnetic valve 4 connects ultrahigh pressure vessel 15 by pipeline.
During use, open nitrogen pipeline electromagnetic valve 1, pressurize from the import of upper seal head 6 to super-pressure vacuum tank 3 by high pressure nitrogen pipeline, the piston 8 of super-pressure vacuum tank 3 moves to super-pressure vacuum tank 3 chamber bottom thereupon, until gas-phase space pressure sensor 13 numerical value is the half of required maximum working pressure, close nitrogen pipeline electromagnetic valve 1.Now open liquid phase pipeline electromagnetic valve 4, pressurizeed to it from lower seal head 11 import by ultrahigh pressure vessel 15, when liquid Space pressure sensor 14 numerical value exceedes gas-phase space pressure sensor 13 numerical value, the nitrogen in super-pressure vacuum tank 3 is compressed, pressure raises, and piston 8 rises.After a period of time, gas-phase space pressure sensor 13 numerical value and liquid Space pressure sensor 14 numerical value can reach balance again, now the piston 8 of super-pressure vacuum tank 3 progressively moves to the centre of super-pressure vacuum tank 3, nitrogen is compressed into the operating pressure of liquid phase, gas-phase space pressure sensor 13 numerical value and liquid Space pressure sensor 14 numerical value increase to the operating pressure of ultrahigh pressure vessel 15, now namely complete the preparation of super-pressure vacuum tank 3.Demolition set 2 during pressure limit, can emit nitrogen, play a protective role in super-pressure vacuum tank 3.
When simulation oil well perforation, the pressure in the ultrahigh pressure vessel 15 be connected with this device can raise due to the effect of explosion wave, in liquid stream excess of imports high voltage stabilizing tank 3, piston 8 moves.After simulation oil well perforation, liquid medium needs to fill up perforating gun cavity, and the pressure in ultrahigh pressure vessel 15 can be caused to reduce, and the liquid stream of super-pressure vacuum tank 3 enters in ultrahigh pressure vessel 15, and the piston 8 of super-pressure vacuum tank 3 moves down.
