Description
Technical field
This utility model belongs to the formation rock experimental evaluation technical field during oil-gas mining,
Particularly relate to a kind of artificial core preparation facilities for the test of rock physicochemical property.
Background technology
Artificial core is widely used in the lab analysis evaluation of formation rock during oil-gas mining,
Important application is have also been obtained in the analysis of rock physicochemical property is tested.Compared to natural core,
The homogeneity of artificial core is more preferable, has contact area more fully with test fluid, is conducive to
Some prominent characteristic that reaction and selective analysis rock or rock are had with fluid matasomatism.Meanwhile,
Compared to granule or the rock sample of powdery, artificial core can keep some structure of natural core
Feature, can test under certain stress condition simultaneously.But artificial core is due to cementing journey
Spending weak, the sampling process after having suppressed often causes sample due to the limitation of sample preparation device design
Product are destroyed.Therefore, strengthen degree of consolidation some auxiliary materials (epoxy resin, cement,
Gypsum Fibrosum powder etc.) often it is added in sample.
But in the physicochemical property of rock sample is tested, even minimal amount of interpolation mineral or fluid are also
Experimental result may be affected.The most this kind of artificial core must use natural rock powder to prepare,
After rock sample has been suppressed, sampling process rock core is fragile.
Summary of the invention
The purpose of this utility model is to provide a kind of artificial for the test of rock physicochemical property
Rock core preparation method, it is intended to after solution rock sample has been suppressed, sampling process rock core is flimsy asks
Topic.
This utility model is achieved in that a kind of described people for the test of rock physicochemical property
The device of lithogenesis heart preparation method, described device includes: include plug, shell, inner sleeve, the end
Seat and jacking block；
Inner sleeve is fixed on base, then uniform application on the outer wall of inner sleeve and the inwall of shell
Lubricating oil, fits together shell with inner sleeve and base.
Further, described inner sleeve is to be combined by two full symmetric semi-cylindricals.
The artificial core preparation facilities for the test of rock physicochemical property that this utility model provides,
Compared with prior art, have the advantage that
(1) preparation process of artificial core is pure physical process, without any interpolation mineral or stream
Body, can retain the physicochemical property of formation rock itself to greatest extent.
(2) core barrel of compacting rock core uses shell and interior Analysis of Nested Design, the sample preparation of all steel
Convenient dismounting after completing, artificial core is hardly damaged, and is pressed into power high.
(3) the artificial core pattern prepared is complete, has certain intensity, Ke Yi
Relevant rock physicochemical property test analysis is carried out under the conditions of effective stress.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below
In conjunction with the embodiments, this utility model is further elaborated.Should be appreciated that this place
The specific embodiment described, only in order to explain this utility model, is not used to limit this practicality new
Type.
Below in conjunction with the accompanying drawings application principle of the present utility model is explained in detail.
Below in conjunction with the accompanying drawings application principle of the present utility model is further described.
First, choose certain mud shale stratum rock sample, after fully drying under the conditions of 80 DEG C, ball mill
Claying into power, 50 grams of the powder of weighed 200 mesh standard sieve nets is stand-by.As it is shown in figure 1,
Artificial core preparation facilities mainly includes plug, shell, inner sleeve, base and jacking block five major part.
After device is carried out and fully dries, inner sleeve 4 is fixed on base 6, then in inner sleeve
Uniform application lubricating oil on the outer wall of 4 and the inwall of shell 3, then by shell 3 and inner sleeve 4
Fit together with base 6.After being completed, ready rock sample powder is loaded inner sleeve
Among 4, then insert plug 1, and in the axial compressive force of the upper end of plug 1 applying 80MPa,
Maintain pressure 60 minutes.After artificial core is compressing, first take out plug 1, then will
Jacking block 2 is put into the top of inner sleeve 4, and by impacting jacking block 2 gently, inner sleeve 4 will be with base 6
Contact surface along inner sleeve 4 and shell 3 together is gradually skidded off, as shown in Figure 2.Such as Fig. 3
Shown in, inner sleeve 4 is to be combined by two full symmetric semi-cylindricals, and therefore inner sleeve 4 is sliding
After going out, two semi-cylindricals are broken into two with one's hands by available hands gently, thus are not damaging artificial core
Under premise, it is easily removed rock core.
According to above-mentioned steps, the artificial core of certain mud shale stratum prepared, result shows
The integrity of artificial core is good, surface whole smooth, can be used for the rock physics and chemistry under stress condition
Performance test.The linear expansion test of one of rock physicochemical property test content is selected at this, right
Artificial core is verified for the feasibility of rock physicochemical property test.This artificial core is used
The rock linear expansion test of (3MPa confined pressure) under stress condition, records this mud shale ground
The layer rock 16 hours linear expansion rate under certain drilling fluid system are 8.06%, and ratio is same
The linear expansion rate that layer rock powdery sample records is low by 3.48%.Result shows, uses this practicality
Artificial core prepared by novel method can be used for the test of rock physicochemical property, and artificial core is being surveyed
Examination can be applied with efficacy, can more fully react the physicochemical property of rock under the conditions of stratum.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this reality
With novel, all made within spirit of the present utility model and principle any amendment, equivalent replace
Change and improvement etc., within should be included in protection domain of the present utility model.
