Abstract
The invention discloses an auxiliary device for permeability tests of a shale sample. The auxiliary device comprises a test sample (3), an upper pressing block (1) and a lower pressing block (2), wherein the test sample (3) is positioned between the upper pressing block and the lower pressing block; the test sample (3), the upper pressing block (1) and the lower pressing block (2) are wrapped by a sealing film (4); internal auxiliary devices (5) are arranged on the sealing film at the contact parts of the test sample (3) and the upper pressing block and the lower pressing block; external auxiliary devices (8) are arranged on the sealing film on the upper pressing block and the lower pressing block. By adopting the auxiliary device, the problems in the prior art that a device for the permeability tests of the shale sample is poor in fastening effect, upper and lower pressing blocks cannot be aligned to the test sample, the surface of the shale sample is relatively highly required, and the like, can be solved.
Description
Technical field
The invention belongs to shale experimental technique, more particularly, to a kind of auxiliary device for shale rock sample permeability test.
Background technology
Shale gas reservoir is that a kind of zonal continuous accumulation type Unconventional forage is hidden, and has and is certainly conigenous storage, uninterrupted confession
Gas, continuous assemble, without the accumulation feature such as migration or minimum distance migration.By there being the development of emphasis in recent years in the whole country
The result of shale gas Resources Strategy investigation: China's shale gas resource potential is big.For realizing 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, it is processed into a diameter of 50mm, highly
Standard specimen for 100mm.In routine test, due to there is original crack inside rock sample, in the case of losing crustal stress,
Rock sample can occur the phenomenons such as rupture or breach；Or do some tests in particular cases, 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, thus leading to shape
Become the oil of confined pressure and formation space to press to obtain water mixing, make test data distortion, also have infringement to testing equipment.
Prior art in installation test test specimen, because human factorss 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 easily distortion；It is diaphragm seal outside test specimen, diaphragm seal is due to it
Plasticity, is susceptible to relatively slide around test specimen, the verity of impact test data；There is trickle lacking in aliquot
Fall into, under the pressure of confined pressure acts on, easily diaphragm seal is crushed, make the water of formation osmotic pressure and the oil mixing of formation confined pressure, right
Testing equipment damages, 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 relatively difficult, often there is iron wire fracture or the effect being unable to reach fastening.Efficiency and the test of test are had a strong impact on
The accuracy of result.
Content of the invention
The technical problem to be solved in the present invention: provide a kind of auxiliary device for shale rock sample permeability test, to solve
Certainly prior art is bad for the device fastening effect of shale rock sample permeability test, and upper lower lock block can not align with sample, and
The problems such as higher to shale rock sample surface requirements.
Technical solution of the present invention:
A kind of auxiliary device for shale rock sample permeability test, it includes sample, upper holder block and lower lock block, and sample is located at upper
Between lower lock block, diaphragm seal is wrapped on sample (3), upper holder block and lower lock block, the diaphragm seal of sample and upper lower lock block contact position
On be provided with interior auxiliary device, the diaphragm seal of upper lower lock block is provided with outer auxiliary device.
Described interior auxiliary device and outer auxiliary device include annular preform and fastening bolt, and annular preform is enclosed within diaphragm seal
On, annular preform is fastened by disjunctor screw rod and fastening bolt.
Annular preform is stainless steel material, and disjunctor screw rod and fastening bolt are iron material.
Diaphragm seal has wrapped up upper holder block and the height of lower lock block more than 30% respectively.
Beneficial effects of the present invention:
The interior auxiliary device of the present invention can make test specimen and upper and lower briquetting mechanical alignment, it is to avoid test specimen discontinuity during test
The generation of phenomenon；The interior auxiliary device of the present invention is arranged on the diaphragm seal at sample and upper lower lock block, plays reinforcing diaphragm seal
The effect being in close contact with upper lower lock block, outer auxiliary device is arranged on the diaphragm seal of upper lower lock block the present invention, makes diaphragm seal
Will not relatively slide；The present invention may also act at the fine defects of sample, it is to avoid confined pressure crushes diaphragm seal, substantially increases and oozes
The accuracy of permeability test, makes test data relatively reliable, is easy to shale to lithology research；Solve prior art for shale
The device fastening effect of rock sample permeability test is bad, and upper lower lock block can not align with sample, and to shale rock sample surface requirements
Higher the problems such as.
Brief description:
Fig. 1 is appearance schematic diagram of the present invention；
Schematic diagram when Fig. 2 uses for the present invention.
Specific embodiment:
A kind of auxiliary device for shale rock sample permeability test, it includes sample 3, upper holder block 1 and lower lock block 2,3, sample
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, and sample 3 pushes with above
Interior auxiliary device 5 is provided with the diaphragm seal of block contact position, the diaphragm seal of upper lower lock block is provided with outer auxiliary device 8.
Described interior auxiliary device 5 and outer auxiliary device 8 include annular preform and fastening bolt 6, and annular preform is enclosed within sealing
On film, annular preform is fastened by disjunctor screw rod 7 and fastening bolt 6.
Annular preform is stainless steel material, and disjunctor screw rod 7 and fastening bolt 6 are iron material.
Diaphragm seal 4 has wrapped up upper holder block 1 and the height of lower lock block more than 30% respectively, to guarantee the sealing function to sample.
Advantages of the present invention has:
1st, pass through using this auxiliary device, sample and briquetting alignment, sample uniform force can be made, in process of the test, sample will not
Crushed, test data is truer.
2nd, pass through using this auxiliary device, diaphragm seal can be pressed on briquetting, preferably play sealing function, improve examination
Test effect.
3rd, in the case that sample has part fine defects, this auxiliary device can be covered in fault location, makes diaphragm seal not
