Abstract

The utility model provides a rock core sample box for simulating the inner structure of a river dike mouth. By using the rock core sample box, the inner structure of the river dike mouth can be really simulated. Partitioning slots are formed in the inner side of each long sideboard at intervals; arc-shaped rock core boards which are shaped in a mould pressing manner and are provided with arc-shaped clamping openings and net-shaped vertical baffle plates can be clamped in the slots; and steel columns which are integrated with the long sideboards are arranged in the partitioning slots and are matched with the clamping openings. The rock core sample box comprises a plurality of cushion blocks, wherein the shape of the horizontal section of each cushion block is the same with that of the horizontal section of each clamping opening; a lubricating oil layer surrounds the inner side wall of a whole outer box body; a sand injecting opening, a liquid injecting opening and a pressurizing opening are sequentially formed in a portion between each two partitioning slots from top to bottom and penetrate in the corresponding long sideboard; and a transparent window is arranged on each short sideboard, and is made of an acrylic material. A rock core obtained by using the rock core sample box can really simulate the inner structure of the river dike mouth; and effective experimental data are provided for exploiting remaining oil in the river dike mouth.

Description

A kind of for simulating the core sample case of dam, river mouth endo conformation

Technical field

The utility model relates to a kind of rock core Preparation equipment being applied in oil-gas field development field.

Background technology

Late high water content period in oil-field development, the high water logging in bottom of dam, river mouth endo conformation sand body, the effect of blocking of interlayer, capital causes the middle and upper part of river channel sand to produce straight well and cannot employ or employ the bad remaining oil of effect because injected water is blocked, in order to provide ripe effectively laboratory study data to the remaining oil exploitation of the inner interlayer shield portions of these dam, river mouths, just need the authentic and valid sand body that simulates dam, river mouth endo conformation.But existing core sample case can only be realized the rock core shape of single shape and make, and cannot realize the making of the core sample of dam, the river mouth endo conformation with complex structure.

Summary of the invention

In order to solve the technical matters of mentioning in background technology, it is a kind of for simulating the core sample case of dam, river mouth endo conformation that the utility model provides.

The technical solution of the utility model is: this kind is for simulating the core sample case of dam, river mouth endo conformation, outer case and the upper cover with a rectangle, on cover the buckle being useful on outer case clamping, its unique distinction is: described outer case forms after being connected with minor face plate and base plate by long side plate; Long side plate and minor face plate and base plate are corrosion resistant plate; At the clear width of long side plate, have and cut apart slot, for arc rock core plate and vertical baffle with circular arc bayonet socket for after mold pressing sizing, snap in; Cut apart in slot and have one and the integrated steel column of long side plate, steel column matches with bayonet socket.Described core sample case also comprises some cushion blocks, and the shape of the horizontal section of cushion block is identical with the shape of the horizontal section of bayonet socket, to realize by regulating the number of described cushion block to control arc rock core plate along the extreme lower position of cutting apart slot decline.The width sum of the width that the width of cutting apart slot is baffle plate and an edge of bayonet socket; Madial wall around whole outer case has a lube layer; Penetrate long side plate and every 2 positions of cutting apart between slot, have successively note sand mouth, liquid injection port and pressurization mouthful from top to bottom.In addition, on minor face plate, have transparent window, the sheet material of transparent window is acryl plates.

The utlity model has following beneficial effect: utilize this kind of core sample case, can select the some blocks of arc rock core plates with circular arc bayonet socket after mold pressing sizing to insert according to dam, river mouth endo conformation cuts apart in slot, by the number of cushion block, adjust position and the angle of arc rock core plate, by vertical baffle, cut apart each arcuate segments, then, in the space of arc rock core plate, inject the grains of sand, add after gluing connecing, then pressurization sizing.Finally, vertical baffle is extracted out, rock core in whole casing is taken out, again through extraneous integral die sizing and oven dry, can access the rock core that can simulate preferably dam, river mouth endo conformation, thereby for the remaining oil exploitation of the inner interlayer shield portions of dam, river mouth provides ripe effectively laboratory study data, for the formulation of oil-gas field development scheme provides scientific basis.

Embodiment:

Below in conjunction with accompanying drawing, the invention will be further described:

If Fig. 1 is in conjunction with as shown in Fig. 2, Fig. 3, this kind, for simulating the core sample case of dam, river mouth endo conformation, has outer case and the upper cover 14 of a rectangle, is useful on the buckle 13 clamping with outer case on upper cover 14, and its unique distinction is:

Described outer case forms after being connected with minor face plate 1 and base plate by long side plate 7; Long side plate 7 and minor face plate 1 and base plate are corrosion resistant plate.At the clear width of long side plate 7, have and cut apart slot 3, for the arc rock core plate 5 with circular arc bayonet socket 6 for after mold pressing sizing and netted vertical baffle 2, snap in; Cut apart in slot 3 and have one and the integrated steel column 4 of long side plate, steel column 4 matches with bayonet socket 6, to realize arc rock core plate 5, can within cutting apart slot, slide along steel column.

Described core sample case also comprises some cushion blocks 8, and the shape of the horizontal section of cushion block 8 is identical with the shape of the horizontal section of bayonet socket 6, to realize by regulating the number of described cushion block to control arc rock core plate 5 along the extreme lower position of cutting apart slot 3 declines.

The width of cutting apart slot 3 is the width sum of the width of vertical baffle 2 and an edge of bayonet socket 6.In addition,, in order to facilitate the taking-up of rock core, around the madial wall of whole outer case, there is a lube layer.

In addition, penetrate long side plate 7 and every 2 positions of cutting apart between slot 3, have successively note sand mouth 12, liquid injection port 11 and pressurization mouth 10 from top to bottom.Meanwhile, have transparent window 9 on minor face plate 1, the sheet material of transparent window 9 is acryl plates, like this, while making rock core, can constantly observe rock core state.

While using this kind of sales kit (SK), first according to dam, river mouth endo conformation, selecting the some blocks of arc rock core plates with circular arc bayonet socket after mold pressing sizing to insert cuts apart in slot, by the number of cushion block, adjust position and the angle of arc rock core plate, by vertical baffle, cut apart each arcuate segments, then, in the space of arc rock core plate, inject the grains of sand, add after gluing connecing, then pressurization sizing.Finally, vertical baffle is extracted out, then the rock core in whole casing can be taken out.
