Abstract
The utility model discloses an auxiliary device for shale rock specimen permeability test, it includes sample (3), go up briquetting (1) and briquetting (2) down, about sample (3) lie in between the briquetting, seal membrane (4) parcel at sample (3), go up briquetting (1) and lower briquetting (2) on, be provided with interior auxiliary device (5) on the seal membrane of sample (3) and upper and lower briquetting contact department, be provided with on the seal membrane of upper and lower briquetting outer auxiliary device (8), the problem of prior art be used for shale rock specimen permeability test's device fastening effect not good, upper and lower briquetting can not align with the sample, and to shale rock specimen surface having relatively high expectations etc is solved.
Description
Technical field
The utility model belongs to shale experimental technique, more particularly to a kind of auxiliary for shale rock sample permeability test is filled
Put.
Background technology
Shale gas reservoir is that a kind of zonal continuous accumulation type Unconventional gas is hidden, with being conigenous storage, uninterrupted confession certainly
Gas, continuous aggregation, without the accumulation feature such as migration or minimum distance migration.By the development for having emphasis in the whole country in recent years
The result of shale gas Resources Strategy investigation：China's shale gas resource potential is big.To realize the high-efficiency mining of shale gas, shale is oozed
The experimental study of permeability is imperative.
In conventional shale permeability test, according to three-axis infiltration experiment rock sample specification, a diameter of 50mm, height are processed into
For the standard specimen of 100mm.In routine test, due to there is original crack inside rock sample, in the case where crustal stress is lost,
Rock sample can occur the phenomenons such as rupture or breach；Or some tests in particular cases are done, during sampling test such as after pressure break,
Due to the high intensity of shale, under the continuous improvement of confined pressure, original diaphragm seal can rupture in indentation, there, so as to cause shape
Oil into confined pressure presses to obtain water mixing with formation space, makes test data distortion, also has infringement to testing equipment.
Prior art in installation test test specimen, because human factor can not make test specimen align with upper lower lock block, during test
Test specimen discontinuity, easily damages test specimen by pressure, test data also easy distortion；Test specimen outside is diaphragm seal, and diaphragm seal is due to it
Plasticity, is susceptible to relative slip around test specimen, affects the authenticity of test data；There is trickle lacking in aliquot
Fall into, under the pressure effect of confined pressure, easily diaphragm seal is crushed, make the water to form osmotic pressure and form the oil mixing of confined pressure, it is right
Testing equipment is damaged, and also affects test data.
Outside diaphragm seal, in order to improve the sealing function of diaphragm seal, generally tied up using iron wire, this kind of method operation
When it is relatively difficult, often there is iron wire fracture or be unable to reach the effect of fastening in Jing.Efficiency and the test of test are had a strong impact on
As a result the degree of accuracy.
Utility model content
The technical problems to be solved in the utility model：A kind of servicing unit for shale rock sample permeability test is provided,
Bad for the device fastening effect of shale rock sample permeability test to solve prior art, upper lower lock block can not be with sample pair
Together, and it is higher to shale rock sample surface requirements the problems such as.
Technical solutions of the utility model：
A kind of servicing unit for shale rock sample permeability test, it includes sample, upper holder block and lower lock block, sample position
Between upper lower lock block, diaphragm seal is wrapped in sample（3）, on upper holder block and lower lock block, sample is close with upper lower lock block contact position
Interior servicing unit is provided with sealer, outer servicing unit is provided with the diaphragm seal of upper lower lock block.
The interior servicing unit and outer servicing unit include annular preform and fastening bolt, and annular preform is enclosed within diaphragm seal
On, disjunctor screw rod and fastening bolt fasten annular preform.
Annular preform is stainless steel material, and disjunctor screw rod and fastening bolt are iron material.
Diaphragm seal has wrapped up respectively the height of upper holder block and lower lock block more than 30%.
The beneficial effects of the utility model：
Interior servicing unit of the present utility model can make test specimen with upper and lower briquetting mechanical alignment, it is to avoid test specimen is received during test
The generation of power non-uniform phenomenon；Interior servicing unit of the present utility model is arranged on the diaphragm seal at sample and upper lower lock block, is risen
To the effect that diaphragm seal is in close contact with upper lower lock block is reinforced, outer servicing unit is arranged on the close of upper lower lock block by the utility model
In sealer, make diaphragm seal relative will not slide；The utility model may also act at the fine defects of sample, it is to avoid confined pressure is crushed
Diaphragm seal, substantially increases the accuracy of permeability test, makes test data relatively reliable, is easy to shale to lithology research；Solution
The device fastening effect that prior art of having determined is used for shale rock sample permeability test is bad, and upper lower lock block can not align with sample,
And it is higher to shale rock sample surface requirements the problems such as.
Description of the drawings：
Fig. 1 is the utility model appearance schematic diagram；
Schematic diagram when Fig. 2 is used for the utility model.
Specific embodiment：
A kind of servicing unit for shale rock sample permeability test, it includes sample 3, upper holder block 1 and lower lock block 2, examination
Sample 3 is located between upper lower lock block, it is characterised in that：Diaphragm seal 4 is wrapped on sample 3, upper holder block 1 and lower lock block 2, sample 3 with
Interior servicing unit 5 is provided with the diaphragm seal of upper lower lock block contact position, outer servicing unit is provided with the diaphragm seal of upper lower lock block
8。
The interior servicing unit 5 and outer servicing unit 8 include annular preform and fastening bolt 6, and annular preform is enclosed within sealing
On film, disjunctor screw rod 7 and fastening bolt 6 fasten annular preform.
Annular preform is stainless steel material, and disjunctor screw rod 7 and fastening bolt 6 are iron material.
Diaphragm seal 4 has wrapped up respectively the height of upper holder block 1 and lower lock block more than 30%, to guarantee the sealing function to sample.
Advantage of the present utility model has：
1st, by the way that sample and briquetting alignment, sample uniform force, sample in process of the test using the servicing unit, can be made
Will not be crushed, test data is truer.
2nd, by using the servicing unit, diaphragm seal being pressed on briquetting, sealing function is preferably played, improves examination
Test effect.
3rd, in the case where sample has part fine defects, the servicing unit can be covered in fault location, make diaphragm seal not
Crushed by confined pressure, improve test effect.
