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 used to tamp the core model main body 2 for filling quartz sand, described
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 long side wall.
Specifically, the core model main body 2 is to use solid steel to draw out rock core size for 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 export the outlet that correspond to three layers 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 movement 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).Screw channel 23 is arranged on two long side wall mainly by the application
Because passage is so arranged so as to uniformly make power, keeps 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 using 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.Being provided with the side wall top surface of core model main body 2 is used for and 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, it is each to import and export 22 and be 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 here 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, 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 tamp 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 blocking has filter cake 52 to reach on projection 51
The effect of gas is discharged, so that the rock core composite testing requirement prepared.
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, conveniently takes for convenience, 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 crude face of polishing.
The utility model is further illustrated below by example.
