Embodiment
The present embodiment relates to a kind of artificial core, it is formed by quartz sand epoxy resin cementitious, as shown in fig. 1, it comprises cross section is the square rock core body 1 in strip, rock core body 1 is provided with a blind hole 2 along its length, in blind hole 2, be filled with not shown quartz sand, and the particle diameter of quartz sand is between 35-40 order.
Utilize above-mentioned artificial core, the needs adjusting stifled fluid-tight to block up test can be met, but due to the certainty of rock core body 1 length, according to the difference of test requirements document, just need the rock core body 1 manufacturing different length, it has certain inconvenience.Therefore as shown in Figure 2 in the present embodiment, make rock core body 1 be the structure in segmented be made up of bottom biock 3, top block 5 and the intermediate mass 4 be connected between bottom biock 3 and top block 5.Thus the difference of intermediate mass 4 quantity be connected between bottom biock 3 and top block 5 can be utilized, realize the adjustment of rock core body 1 length.
The structure of bottom biock 3 as shown in Figure 3, one end end face of bottom biock 3 is provided with bottom biock dovetail groove 11, and bottom biock 3 is also provided with the bottom blind hole 12 be opened in bottom biock dovetail groove 11.The structure of intermediate mass 4 as shown in Figures 4 and 5, is provided with intermediate mass dovetail groove 21 and intermediate mass dovetails 22 in the two ends correspondence of intermediate mass 4.Namely intermediate mass 4 is connected in bottom biock 3 via the intermediate mass dovetails 22 on it has on the end face of bottom biock dovetail groove 11.Intermediate mass 4 is also provided with the intermediate throughholes 23 in the intermediate mass dovetail groove 21 that is opened on respectively and in intermediate mass dovetails 22, and intermediate throughholes 23 is when intermediate mass 4 is connected in bottom biock 3, with the bottom biock blind hole 12 in bottom biock 3 in coaxial.
The structure of top block 5 as shown in figures 6 and 7, one end end face of top block 5 is provided with top block dovetails 31, and top block 5 is connected in intermediate mass 4 via the top block dovetails 31 on it to be had on the end face of intermediate mass dovetail groove 21.Top block 5 to be provided with on offering thereon in one end top block dovetails 31 and to run through the top through hole 32 of top block 5, and top through hole 32 is when top block 5 is connected on intermediate mass 4, with the intermediate throughholes 23 on intermediate mass 4 in coaxial.After bottom biock 3, intermediate mass 4 and top block 5 are connected together, bottom blind hole 12, intermediate throughholes 23 and top through hole 32 are connected to form the blind hole 2 on rock core body 1, and are also all filled with cementing agent between each dovetail groove matched and dovetails.
The structure of rock core body 1 time in Fig. 2 of the present embodiment for only having an intermediate mass 4, when reality uses, according to the difference of test to rock core body 1 length requirement, the magnitude setting of intermediate mass 4 can carry out unrestricted choice, when using multiple intermediate mass 4, adjacent intermediate mass 4 can realize being connected via the intermediate mass dovetail groove 21 on it and intermediate mass dovetails 22, is also all filled with cementing agent between each dovetail groove matched and dovetails.And in order to make the more firm of snap-fit engagement between each dovetail groove and dovetails, each dovetails and corresponding dovetail groove can be made in the present embodiment to be the wedge shape that cross sectional area is gradually little along its length, but also the physical dimension of each dovetails can be made slightly larger than the physical dimension of the dovetail groove be mated, also can improve the fastness after both clampings thus further.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
