Abstract
The utility model discloses an auxiliary device for drilling rock samples in a laboratory and aims to overcome the shortcoming that the conventional rock core drill in China can only drill the rock samples in three directions (an x direction, a y direction and a z direction) of a cylinder rock core. The auxiliary device is suitable for drilling the rock samples in different directions in the laboratory, so that the influence, caused by a space effect, on the mechanical property of rock and ground stress corresponding to the rock samples in all the directions can be tested in the laboratory through a mechanical experiment instrument and a sound emission test system. An experiment table comprises a rock sample arrangement sleeve, slot holes, a supporting frame, a device base, a rock sample fixing device, a hinge pin shaft and drilled holes. By the use of the structural characteristics (the supporting frame is hinged to the drilled holes in the bottom of the rock sample arrangement sleeve and the device base) of the auxiliary device, the rock samples of the rock core to be drilled in different directions can be drilled, and experiments such as test on the influence, caused by a direction effect, on the mechanical property of the rock and test on the three-dimensional ground stress of the rock through a sound emission tester can be carried out.
Description
Technical field:
The utility model relates to the servicing unit of a kind of laboratory boring sample, it is applicable to laboratory and drills through same core different directions rock sample, and then can utilize in laboratory Rock Mechanics Test And instrument and Acoustic Emission Testing System, test mechanical properties of rock is subject to the impact of steric effect and the three-dimensional ground stress at place, rock sample place.
Background technology:
Rock Mechanics Test And obtain rock sample mechanics parameter the petroleum engineering aspects such as Optimized fracturing design, wellbore stability research and stress direction mensuration are played to extremely important effect; And Rock Mechanics Test And is the experiment that directly adopts natural rock to carry out substantially, experiment more approaches field geology reality like this; The factor that a lot of documents records affect Rock Mechanics Test And is mainly divided into two classes: a class is the character of rock itself: as rock composition, density, rate of decay, anisotropy etc.; Another kind of is experiment and environmental baseline: as erosion, temperature, loading speed etc.; And as buried the impact of direction and utilizing the research of place, acoustic emission test rock sample place three-dimensional ground stress, be not also a lot of for the locus of rock sample, mainly due to cannot be on the basis of existing core-drill(ing) machine, obtain the rock sample of same core all directions, and then can not utilize single factor analysis method to control D-factor to the impact of rock sample mechanical property, also cannot test 3 rock sample terrestrial stress that particular orientation is corresponding.
Utility model content:
The utility model proposes the servicing unit of a kind of laboratory boring sample, can only drill through the drawback of rock sample of 3 directions of right cylinder rock sample in order to solve existing core-drill(ing) machine, be three direction rock samples of x, y, z (suppose that in advance cylinder axis is to being y direction, the both direction of vertical cylindrical body axial direction section is respectively x and z direction).
The utility model comprises rock sample placement sleeve, slotted eye, bracing frame, device pedestal, rock sample stationary installation, described rock sample is placed sleeve and is placed on bracing frame by welding manner, the boring that support frame as described above is placed sleeve bottom by the boring at two ends respectively at boring and the rock sample of device pedestal is hinged, by converting different articulated position between them and the height of bracing frame, change rock sample and place the angle of sleeve and device pedestal, thereby drill through the rock sample of different directions, described slotted eye is placed sleeve downside in rock sample, for fear of drill bit sampling process drill bit, contact rock sample and place sleeve, described rock sample stationary installation can clamp rock sample by tightening a side nut and screw rod, and weld together by hinging pin shaft and the rock sample placement sleeve of a side.
Advantage and the good effect that the utlity model has are: utilize this novel design feature, can drill through the rock sample for the treatment of coring different directions, by the Experiments of Machanics of carrying out to different directions rock sample, thereby can the impact of test space directive effect on mechanical properties of rock, utilize the terrestrial stress of rock sample in xy45 ° of acoustic emission test instrument test, xz45 °, yz45 ° three particular orientation simultaneously, and then in conjunction with the terrestrial stress of x, y, z direction rock sample, can calculate the size and Orientation of three principle stresses of rock sample.

Embodiment:
For further understanding summary of the invention of the present utility model, Characteristic, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The utility model is the servicing unit of a kind of laboratory boring sample, can assist existing core-drill(ing) machine to drill through the rock sample of same core different directions.And existing core-drill(ing) machine can only drill through three directions of x, y, z, the introduction of lower mask body drills through the process of different directions core.
First rock sample 13 being placed on to rock sample places in sleeve 6, utilize fixedly rock sample 13 of rock sample stationary installation 8 fastening nuts 4, then the utility model device is placed between horizontal clamping device 2, core-drill(ing) machine drill bit 1 above the utility model in vertical state, for core-drilling:
At accompanying drawing 1(a) in, bracing frame 7 is hinged with boring 11, make device pedestal 10 and rock sample place sleeve 6 bottoms and become 60 ° of angles, by rotating the position of rock sample 13 in rock sample is placed sleeve 6, the nut 4 of tightening rock sample stationary installation 8 is rock sample 13 fixedly, vertical lower the boring of drill bit of drilling machine 1, drills through 3 corresponding particular orientation rock samples, is respectively xy60 °, xz60 °, yz60 ° direction;
At accompanying drawing 1(b) in, change the articulated position of bracing frame 7 and boring 11, make device pedestal 10 and rock sample place sleeve 6 bottom angles at 45 °, open rock sample stationary installation 8, by rotating the position of rock sample 13 in rock sample is placed sleeve 6, the nut 4 of then tightening rock sample stationary installation 8 is rock sample 13 fixedly, the vertical lower brill of drill bit of drilling machine 1, can drill through 3 corresponding particular orientation rock samples, be respectively xy45 °, xz45 °, yz45 ° direction;
