Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below the present invention in technical scheme carry out clearly
Chu, it is fully described by, it is clear that described embodiment is a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Refer to Fig. 1-4, the multi-functional heterogeneous core simulator that the application is provided, including core model main body 2, top
Lid 1 and supporting tamp module 5；The supporting module 5 of tamping is described for tamping the core model main body 2 for filling quartz sand
Top cover 1 is used to work as the opening tamped and finish core model main body 2 described in rear enclosed；
Being set respectively on four side walls of the core model main body 2 has import and export 22 and screw channel 23, the turnover
Mouth 22 is separately positioned on two broad side walls of core model main body 2, and screw channel 23 is separately positioned on core model main body 2
On two side walls long.
Specifically, the core model main body 2 is that to use solid steel to draw out rock core size be 500 × 100 × 80mm
Cavity, lower part is the iron plate of 50mm thickness, and being respectively perpendicular direction on the opposite side wall of the core model main body 2 is uniformly distributed
Three import and export, this three outlets correspond to three layers of outlet of heterogeneous each layer respectively.At other 2 of core model main body 2
Some full screw channels 23 are distributed with contrast side wall, the screw channel 23 of one of side wall is used for by being screwed
(adjusting method is for permeability that screw screws in inside it to adjust rock core：To load in core model main body 2 quartz sand it
Before, first it is close to the side wall and places one piece of iron plate to block the screw channel on this side wall, quartz sand is then refilled, when by surveying
When the permeability of examination rock core is undesirable, by rotating the screw in the screw channel, screw promotes iron plate to move and then right
Rock core further presses, so as to reach the purpose of the permeability of regulation rock core)；Screw channel on another side wall, Ke Yian
Loading electrode or sensor, obtain related experiment parameter and (when that need not obtain related experiment parameter, again may be by placing
One piece of iron plate blocks the screw channel on this side wall).Be arranged on two side walls long screw channel 23 mainly by the application
Because passage is so arranged so as to uniformly make power, keep under conditions of rock core uniformity, change the effect hand such as core permeability
Section；Secondly, channeling it is multi-functional (act not only as being used during permeability test, be also used as install electrode or
The passage of sensor).
As shown in Fig. 3 and its Fig. 7, the top cover 1 is fixed in core model main body 2 to fix rock core by screw 4,
Sealing ring sealing model is inlaid with inside the top cover 1.The side wall top surface of core model main body 2 be provided with for the top cover
The screw hole 26 of connection.
Further, multi-functional heterogeneous core simulator as described above, as shown in fig. 7, in core model main body 2
Broad side walls on vertical direction be distributed with 3 it is described import and export 22, each is imported and exported and 22 is correspondingly arranged on the inside of broad side walls
There is a flow-guiding channel 24, screen pack 25 has been blocked on each flow-guiding channel 24.
Specifically, the purpose that the application designs flow-guiding channel 24 herein is when rock core permeability test is done, from institute
State import and export the water that flows into and out can be with uniformly penetrating to rock core in, while the screen pack 25 can avoid rock core sand body from overflowing
Go out.
Further, multi-functional heterogeneous core simulator as described above, supporting the tamping is provided with module 5
With projection 51, the projection 51 is adapted with cavity cross-sectional area specification hollow in core model main body 2, for tamping rock
The heart；A through hole is provided with projection 51, closure has filter cake 52 on the through hole.
Specifically, the projection 51 is used to tamp the quartz sand in core model main body 2；Because quartz sand is in the mistake tamped
Portion gas generation is had in journey, therefore, the application is used to be set by and closure has filter cake 52 to reach on projection 51
The effect of gas is discharged, so that the rock core composite testing requirement for preparing.
Further, multi-functional heterogeneous core simulator as described above, in order to mitigate the supporting weight for tamping module 5
Projection 51 is designed as boring structure by amount, the application.
Further, multi-functional heterogeneous core simulator as described above, dismantles for convenience, conveniently takes, this
Application is provided with top cover handle 11 on the top cover 1, and handle 21 is provided with the core model main body 2.
Further, multi-functional heterogeneous core simulator as described above, for the ease of quartz particles and wall
Contact, the inwall of the core model main body 2 is the crude face of polishing.
The present invention is further illustrated below by example.
Embodiment：
(1) assembling of the model is carried out：
1. cover plate is put into O-ring, coating lubricating oil is stand-by；
2. prepare electrode, be fixed in incorporation model；
3. it is installed into outlet valve；
4. back-up sand operation is carried out：General back-up sand in three times, is respectively filled in the quartz sand (ground floor of 400g different meshes every time
120-160 mesh, second layer 80-100 mesh, third layer 60-80 mesh) three layers of heterogeneous core are manufactured, each layer of use strikes off instrument
(as shown in Figure 7) adds next layer of quartz sand and strikes off after striking off, after three layers add, weighed using scale, is higher by buffed surface 0.3cm
Swaging operation (test of many times result shows 0.3cm) can be applied, using corresponding compacting tool set 50MPa constant pressures 5 minutes, finally put
Enter die assembly shaping.
(2) Related Experimental Study is carried out：
A, sealing：The closing port of export, arrival end connection nitrogen cylinder, after constant pressure 10MPa injection models, lets out
Leakage, voltage stabilizing 5 minutes；After pressure release, after carrying out perm-plug method, gas cylinder is closed, open valve and deflate, carry out b operations, such as Fig. 5.
B, water survey permeability：Carry out water and survey permeability experiment, connect experiment flow, one end connects intermediate receptacle, and one end is adopted
Pore volume is surveyed with " degassing method ", ensures that mould is not having gas to scurry out after being continuously injected into 2L water, that is, obtain pore volume.
C, waterflood front saturation degree are determined：Connection electrode signal receiver, proceeds by flood-pot experiment, according to electrode telecommunication
Number display, can determine that Waterflooding front and saturation degree change by the change of rock core diverse location electric signal.Fig. 6 is rock
The waterflood front time plot that displacement electrode is determined at the heart 1/2.
Rock core after d, experiment, is detachable rock core mould according to the contragradience of assembling suddenly, and the filling after cleaning next time is only
Need to change cushion rubber.
Finally it should be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
The present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those within the art that：It still may be used
Modified with to the technical scheme described in foregoing embodiments, or equivalent is carried out to which part technical characteristic；
And these modification or replace, do not make appropriate technical solution essence depart from various embodiments of the present invention technical scheme spirit and
Scope.
