Description
Technical field
Patent of the present invention is related to oil field experimental rig, specifically places formula pressure compensation HTHP simulation dress vertically
Put.
Background technology
As oil field at home developed to the middle and later periods, the difficulty of exploitation is increasing, wellbore environment worse and worse, pressure is high,
Temperature is high.Therefore requirement to downhole tool also more and more higher, so the downhole tool of research and development high temperature high voltage resistant turns into when business
It is anxious, for the performance of more preferable verification tool, it is necessary to HTHP analogue means is designed, because common HTHP is simulated
Device can not carry out high-potting for a long time, it is impossible to the high-pressure situations in effective simulation shaft bottom, in order to solve this problem, and design
It can carry out pressure compensated HTHP analogue means.
The content of the invention
The purpose of patent of the present invention, which is to provide, places formula pressure compensation HTHP analogue means vertically, can be more real
Simulate the situation of actual pit shaft, it is ensured that the reliability of test instrument.
In order to reach above-mentioned purpose, patent of the present invention employs following technical scheme, places formula pressure compensation HTHP vertically
Analogue means, including external pressure connecting tube, outer tube, inner sleeve, the outer tube empty set is in the outside of inner sleeve and outer tube
The bottom of external pressure connecting tube is both connected to the upper end of inner sleeve, heating oil ring sky, institute are formed between the outer tube, inner sleeve
State in inner sleeve by the vertical hanging test instrument of test instrument connecting tube.
The external pressure connecting tube upper port is fixed with the interior crimp head stretched into inside external pressure connecting tube, institute by joint gland
Test instrument connecting tube upper end is stated to be connected by hoop with interior crimp head lower end into external pressure connecting tube inside.
The external pressure connection pipe outer wall opens up a radial direction through hole led to inside external pressure connecting tube respectively and one leads to
The empty axially extending bore of oil ring is heated, an external pressure hydraulic test pump is connected at radial direction through hole, a compensation is connected at axially extending bore
Hydraulic test pump.
The inner sleeve threaded upper ends formula is connected to external pressure connecting tube bottom inwall, and the external pressure connecting tube bottom outer wall is opened
If evagination shoulder, the outer sleeve upper screw-type connection is in outer bell and spigot joint inwall, overcoat upper end of joint screw-type connection external pressure
Set, the outer gland are connected on the evagination shoulder, and sealing is set between the overcoat upper end of joint inwall and evagination shoulder
Circle.
The outer bell and spigot joint outer wall sets oil drain pan.
Heating oil-in and heating oil outlet are set on the outer tube.
Compared to prior art, patent of the present invention has the advantages that：
The device is reserved with the oily circulation port of high-temperature heating first, and height can be achieved by connecting high-temperature heating oil circulation device
Temperature experiment, test instrument are heated evenly；Secondly high pressure simulation experiment can be achieved, be no more than because the sleeve pipe of routine bears internal pressure
It 70MPa, can not just be tested when pressure testing is more than 70MPa, in order to meet that compression test under super high is simulated, be added again outside test casing
One layer of outer tube, during high-potting, certain compensation pressure is stamped in two layers of casing annulus, inner sleeve is maintained at it can hold
Within the pressure differential range received, at this moment internal pressure test tool can meet compression test under super high, while can pass through the pressure of each several part
Table observes directly the change of pressure；3rd, the analogue means can more really simulate actual pit shaft using formula is placed vertically
Situation, it is ensured that the reliability of test instrument.
Brief description of the drawings
Fig. 1 is the structural representation for placing formula pressure compensation HTHP analogue means vertically of patent of the present invention；
In figure, crimp head, 2 joint glands, 3 external pressure connecting tubes, 4 external pressure hydraulic test pumps, 5 outer glands, 6 are socketed outside in 1
Head, 7 oil drain pans, 8 outer tubes, 9 inner sleeves, 10 test instruments, 11 compensation hydraulic test pumps, 12 test instrument connecting tubes, 13 hoops.
Embodiment
Detailed description and technology contents about patent of the present invention, coordinate brief description of the drawings as follows, but accompanying drawing only provides ginseng
Examine and purposes of discussion, be not used for being any limitation as patent of the present invention.
According to Fig. 1, formula pressure compensation HTHP analogue means is placed vertically, including it is external pressure connecting tube 3, outer tube 8, interior
Sleeve pipe 9, outer tube empty set are both connected to the bottom of external pressure connecting tube in the upper end in the outside of inner sleeve and outer tube and inner sleeve
End, heating oil ring sky is formed between outer tube, inner sleeve, passes through the vertical hanging test work of test instrument connecting tube 12 in inner sleeve
Tool 10.The upper port of external pressure connecting tube 3 is fixed with the interior crimp head 1 stretched into inside external pressure connecting tube by joint gland 2, tests work
Tool connecting tube upper end enters inside external pressure connecting tube to be connected with interior crimp head lower end by hoop 13.External pressure connection pipe outer wall difference
Open up a radial direction through hole led to inside external pressure connecting tube and one leads to the empty axially extending bore of heating oil ring, in radial direction through hole
One external pressure hydraulic test pump 4 of place's connection, a compensation hydraulic test pump 11 is connected at axially extending bore.Inner sleeve threaded upper ends formula is connected to
External pressure connecting tube bottom inwall, external pressure connecting tube bottom outer wall open up evagination shoulder, and outer sleeve upper screw-type connection is in overcoat
The inwall of joint 6, the outer gland 5 of overcoat upper end of joint screw-type connection, the outer gland are connected on the evagination shoulder, outer socket
Sealing ring is set between head upper end inwall and evagination shoulder.Outer bell and spigot joint outer wall sets oil drain pan 7.Heating oil is set on outer tube
Entrance 14 and heating oil outlet 15.
Compensation hydraulic test pump 11, test instrument connecting tube 12 and interior crimp head 1 are connected first, are then placed in by external pressure
In pipe after connecting tube 3 and the connection of inner sleeve 9, jointing gland 2, then the tool string assembled is entirely put into by outer
In bell and spigot joint 6 and outer tube 8, outer gland 5 is tightened, finally high temperature oil pipeloop is connected.
After test string connects, if instrument tries internal pressure, pressure testing pipeline examination internal pressure is connected at interior crimp head 1,
Until instrument reaches the performance indications of design；When instrument tries external pressure, external pressure hydraulic test pump 4 is suppressed to external pressure connecting tube 3 and experiment
What annular space between instrument 10 carried out instrument holds external pressure test, when pressure reaches the maximum pressure of inner sleeve 9, passes through and compensates examination
Press pump 11 suppress the pressure difference for the annular space between outer tube 8 and inner sleeve 9 bearing, inner sleeve 9 always rational scope it
It is interior, and its internal pressure can improve a lot, so meet the test requirements document of most of downhole tool；When needing hot test
When, high temperature oil pipeloop is coupled with the heating oil-in 14 and heating oil outlet 15 reserved on outer tube 8, passes through height
Hot test can be achieved in temperature heating oil circulation device.
The preferred embodiment of patent of the present invention is the foregoing is only, is not used to limit the scope of the claims of patent of the present invention, its
He uses the equivalence changes of the patent spirit of patent of the present invention, all should all belong to the scope of the claims of patent of the present invention.
