Technical Field
[0001] This utility model belongs to the field of petroleum exploration technology, and in particular relates to an automatic core detection device for petroleum exploration. Background Technology
[0002] Core testing involves obtaining core samples from wells and analyzing their physical properties, pore structure, oil saturation, and other parameters in the laboratory to assess the permeability and productivity of the reservoir. This provides crucial data support for oil and gas field development and is an indispensable technical link in the petroleum industry.
[0003] A search revealed a core grinding and scanning device disclosed in publication number CN222895962U, which includes a conveying mechanism. While this device can improve detection efficiency, it still has the following problems in use:
[0004] 1. The core lacks support during movement, making it unstable and prone to sinking during grinding and movement;
[0005] 2. Poor core fixation and instability during the moving and grinding process pose a risk of danger. Therefore, an automatic core detection device for petroleum exploration is proposed. Utility Model Content

The surface of the conveyor belt is provided with an upper pressure plate, and the bottom of the upper pressure plate is fixed with a lower pressure plate by bolts. The upper pressure plate and the lower pressure plate are arranged parallel to each other and form a clamping channel between them for clamping the conveyor belt. Guide grooves are opened on the inner walls of both sides of the conveyor. The two sides of the lower pressure plate slide with the two guide grooves respectively. Through the cooperation between the upper pressure plate, the lower pressure plate and the guide grooves, the core can be more stable when moving and grinding, and there will be no sinking problem during the grinding process.
[0010] A clamping mechanism is mounted on the surface of the upper pressure plate, and the lower pressure plate slides with the guide groove to maintain stable movement of the clamping mechanism.
[0011] A grinding mechanism, which is positioned above the conveyor, is used for grinding the rock core.
[0012] A scanning mechanism is positioned above the conveyor for core inspection.
[0013] As a further embodiment of this utility model, the clamping mechanism includes a fixed cylinder fixed to the surface of the upper pressure plate. Clamping assemblies are provided on both sides of the fixed cylinder. Each clamping assembly includes a clamping frame and a guide plate. The clamping frame slides through one side of the fixed cylinder. One end of the clamping frame is fixedly connected to an arc-shaped clamping plate for clamping the core. The clamping plate is located inside the fixed cylinder. The guide plate is fixed to one side of the conveyor to guide the movement of the clamping frame and thus clamp the core. One end of the guide plate is provided with an inclined guiding surface. Through the cooperation of the clamping plate and the guide plate, when the core moves, the clamping frame can drive the clamping plate to clamp and fix the core under the action of the guide plate, thereby improving the stability during grinding.
[0014] As a further embodiment of this utility model, the end of the clamping frame away from the rock core is rotatably connected to a roller, and the opposite side of the clamping plate is glued with a rubber plate.
[0015] As a further embodiment of this utility model, the grinding mechanism includes a first mounting frame fixed to the top of the conveyor. The first mounting frame is fixedly connected to the top of the first mounting frame, and a gantry frame is fixedly connected to the top inner wall of the gantry frame. A cylinder is fixedly connected to one end of the piston rod of the cylinder, and a sliding frame is fixedly connected to one end of the cylinder piston rod. The sliding frame slides through the top of the first mounting frame. Two symmetrically arranged mounting plates are fixedly connected to the bottom of the sliding frame. Two transmission rollers are rotatably connected between the two mounting plates, and a grinding belt is driven between the two transmission rollers. A first motor is fixedly connected to one side of one of the mounting plates, and one end of the output shaft of the first motor is fixed to one of the transmission rollers.
[0016] As a further embodiment of this utility model, a dust removal component is also provided on the top of the first mounting frame. The dust removal component includes a fan and a filter cartridge fixed on the top of the first mounting frame. The exhaust end of the fan is fixedly connected to the exhaust end of the filter cartridge. A telescopic pipe is fixed to the inlet end of the filter cartridge. A dust collection box is fixedly connected to one end of the telescopic pipe. The dust collection box is fixed to one end of the two mounting plates.

[0019] As a further embodiment of this utility model, the conveyor is threaded with support columns at the four corners of its bottom, and rubber pads are fixed to the bottom of the support columns.
[0020] In this application, during use, the core sample to be tested is placed in the fixed cylinder, the conveyor is started, and the upper and lower pressure plates are displaced via the conveyor belt. The upper pressure plate moves the fixed cylinder and the core sample, while the lower pressure plate is guided and supported by the guide groove, making the core sample more stable during movement and preventing sinking during grinding. When the clamping frame moves to one side of the guide plate, the clamping frame, under the action of the guide plate, moves the clamping plate to clamp and fix the core sample, improving stability during grinding. When the core sample moves to the lower side of the grinding belt... When the fan and cylinder are started, the cylinder drives the sliding frame to move downwards, which in turn brings the grinding belt into contact with the top of the core. The first motor is then started, and it drives the grinding belt to rotate through the transmission roller, thereby grinding the core. At the same time, the dust generated during grinding enters the filter cartridge after passing through the dust collection box and is collected to avoid polluting the air at the site. After grinding, the core passes through the brush roller, which cleans the top of the core to prevent residual dust and facilitate scanning. Finally, the core is conveyed to the hyperspectral imaging equipment for detection.
[0021] The embodiments of this utility model have the following beneficial effects:
[0022] In this invention, the cooperation between the upper pressure plate, the lower pressure plate and the guide groove makes the core more stable during movement and grinding, and prevents it from sinking during the grinding process.
[0023] In this invention, the use of clamping plates and guide plates in combination enables the clamping frame to clamp and fix the rock core under the action of the guide plate when the rock core is moved, thereby improving the stability during grinding.
[0024] In this invention, the core is more stable during movement and grinding, and there is no sinking problem during the grinding process. At the same time, the clamping frame can drive the clamping plate to clamp and fix the core under the action of the guide plate, which improves the stability during grinding.
[0025] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
