Abstract
A kind of high temperature core holding unit is the utility model is related to, rock core plunger confined pressure and axis pressure can be controlled by pressue device under the conditions of 1000 DEG C.Clamper casing is made using High-temperature resistant alloy material, is set on casing and is pushed away button and pulling buckle, is connected by push-pull wire with external pressue device, made in push-and-pull button cinching process, confined pressure is added to rock core.Both ends use fixed plug and movable drain plug, and equally carrying out axis pressure using push-pull wire applies.
Description
Technical field
A kind of clamping device for applying confined pressure and axis pressure to column rock core of the utility model design, especially can be in high temperature
The core holding unit used under environment.
Background technology
In recent years, with the adjustment of global energy structure, based on tight sand, shale, coal petrography, hydrate etc. very
The dynamics of rule resource exploitation is gradually increased, and needs to carry out reservoir storey increase design in actual recovery process, high-temperature heat treatment storage
Layer is the storey increase design measure of one of which.Rock under laboratory experiment simulation Original strata stress environment is needed to be heat-treated.
In the prior art, CN 102778417B disclose a kind of high pressure high temperature core holding unit, it is with high temperature resistant
The characteristics of high pressure, light weight, but the bush material used is polyether-ether-ketone, and the maximum temperature born is 250 DEG C.In CN
A kind of slip-type ultrahigh temperature core catcher is disclosed in 2932388Y, designs 350 DEG C of maximum temperature, both the above clamper is set
Meter highest carrying temperature also much can not meet simulation high-temperature heat treatment experimental temperature.
Utility model content
In view of the above problems, the utility model provides a kind of high temperature core holding unit device, which can be at 1000 DEG C
It is safe and accurate under environment to apply confined pressure and axis pressure to rock core.
The utility model solves the scheme that its technical problem uses：A kind of high temperature core holding unit device,
The clamper includes alloy sleeve, and the alloy sleeve includes rock core, bracing wire, ejector sleeve, pulling buckle and pushes away button, institute
Push away button and the pulling buckle stated are respectively welded at casing top, and cylinder, which pushes away button side and is drilled with, pushes away button hole, is drawstring through and pushes away the connection of button hole
In pulling buckle, the bracing wire other end passes through ejector sleeve, and the additional depressor of external stove；
The button that pushes away is connected with ejector sleeve, and the additional depressor of external stove.
A rock core plug is respectively placed at the rock core both ends, is movable drain plug and fixed plug respectively, plug and rock core
Close contact is positioned in circular casing jointly；
There is push plate outside the fixed plug, connecting rod is housed in push plate, connecting rod is connected with bracing wire；
There is push plate outside the movable drain plug, push plate outer end is drilled with hole, and by being drawstring through for connecting rod, ejector sleeve is connected to push plate
On.
Using cylindrical type sleeve made of solution strengthening type high-temperature alloy material as rock core casing, the both ends point on casing
Not She Zhi one push away button and pulling buckle, by the metal pipe line of connection, button will be pushed away, pulling buckle distance tenses, pipe skin girth shortens, and produces
Circumferential stress, applies radial load so as to clamp column.Solution strengthening type high-temperature alloy material system is respectively adopted at casing both ends
Into fixed plug and movable drain plug, by push-pull wire, the draw back plate on plug is tensed, gives rock core to apply axial force.Device
Using solution strengthening type high-temperature alloy material, there is high temperature resistant.
Push-pull wire is made of ejector sleeve and bracing wire, and ejector sleeve is welded on the outer shroud for pushing away button, equally uses solution strengthening type high temperature
Alloy material, is drawstring through and pushes away button hole, is welded in pulling buckle, uses SUS304 metal materials, high temperature resistance, has stronger
It is flexible.
Capstan winch spooler is used outside clamper, capstan winch is installed on V-type bar outer end, and ejector sleeve 2 is connected to the other end, and bracing wire is worn
Cross ejector sleeve to twist on spooler, V-type bar is by hydraulic cylinder pressurizing and propping, and when line tenses, oil pressure rises, and the power applied at this time can
To be calculated by hydraulic coupling.
The beneficial effects of the utility model are, under conditions of 1000 DEG C of highest rock core can be given to apply stress, and can
It is simple in structure with hot stove outer control stress intensity, it is reliable and stable.

In Fig. 1, rock core is put among casing 7, by using Fig. 3 pressurizers, bracing wire 2 is pulled out so that push away button 3,
Pulling buckle 4 tenses, and just adds confined pressure to rock core 6.
In fig. 2, in one insertion fixed plug 12 of casing, the other end is put into movable drain plug 10, by using another
Such as the pressurizer of Fig. 3, the plug at both ends is tensed, axis pressure is added to rock core.
In figure 3, pressurize to ejector sleeve 1, bracing wire 2, first by spooler 15 by bracing wire pretension, only rod 19 will be returned and be inserted into
Hole on spooler 15, prevents bracing wire from withdrawing, and is pressurizeed by hand pump to pressure rod, 16 outer bar of V-type bar is outwards elapsed, so that
Bracing wire 2 is drawn out.
The utility model is illustrated by way of example above, but the utility model is not limited to above-mentioned specific implementation
Example, all any changes done based on utility model or deformation belong to the scope of the requires of the utility model protection.
