Embodiment Construction

[0048] The present invention will be further described below in conjunction with the accompanying drawings.

[0049] Such as figure 1 As shown, the low-strength rock sample preparation device with a weak interface is composed of a diamond wire saw machine 1, a workbench 2, and a grinder 3 arranged on a base 4. Refer to Figure 5 , a cutting table 15 and a clamping turntable 16 are set on the workbench 2, and the diamond wire saw machine 1 spans the base 4 through the steel brackets 7 on both sides. The rail 6 passes under the diamond wire saw machine 1, and the workbench 2 can move horizontally on the translation slide rail 6. The workbench 2 can move the cutting table 15 or the clamping turntable 16 to the diamond wire 14 of the diamond wire saw machine respectively. Below, the workbench 2 can also move the cutting table 15 below the grinding cylinder 32 of the grinding machine 3 . The workbench 2 is provided with a propulsion handwheel 27, and the workbench 2 is controlled...

Abstract

The present invention relates to a low-strength rock sample preparation device with a weak interface and a sample preparation method thereof, wherein the low-strength rock sample preparation device with a weak interface is composed of a diamond wire saw machine, a workbench, and a grinding machine arranged on a base. The cutting table and clamping turntable are set on the table, and the diamond wire saw machine spans the base through the steel brackets on both sides; the diamond wire of the diamond wire saw machine is wound outside the two power wheels, and the cooling air nozzle is set on the diamond saw Below the wire; the cutting table includes a cutting seat, a cutting frame, a clamping handle, a positioning card slot, a circumferential rotation device, and a rotating hand wheel. The cutting seat and the cutting frame are fixedly connected by a vertical adjustment device. The cutting frame has two corresponding The upper ends of the two supporting bodies are all formed with positioning slots, and the upper end of one of the supporting bodies is also provided with a circumferential rotation device, which is connected to a circular module, and the upper end of the other support body is also provided with a clamping device , the clamping device connects another circular module. The cutting process of the present invention has little damage to rock samples, high cutting precision and smooth cutting surface.

Description

technical field [0001] The invention relates to a rock mechanics sample preparation tool in the fields of rock mechanics engineering, petroleum engineering, mining engineering and the like, in particular to a device for preparing a low-strength rock sample with a weak interface and a method for preparing the sample. Background technique [0002] At present, the development of unconventional oil and gas resources has attracted worldwide attention. Mechanical parameter testing is an important method to study the mechanical properties of unconventional reservoir rocks. Most of the rock samples used in rock physical and mechanical testing are cylindrical, such as uniaxial, The triaxial compressive strength test requires the rock sample size to be φ25mm*50mm, φ50mm*100mm, and the Brazilian splitting test requires the rock sample size to be φ50mm*25mm. At present, it is very difficult to prepare columnar rock samples of jointed coal rock, mudstone, oil shale and other unconvention...
