Rock debris automatic detection system and method

Abstract

The invention discloses a rock debris automatic detection system and method. The system comprises an image acquisition unit, a sorting mechanism, a vibration disc, a transmission mechanism and a PLC.The image acquisition unit is erected above the transmission mechanism; the sorting mechanism and the vibration disc are connected in series in the transmission mechanism; and the PLC is connected with the transmission mechanism, the sorting mechanism, the vibration disc and the image acquisition unit. The method comprises the steps that rock debris is guided into the transmission mechanism, dry and wet materials are distinguished and sorted through image acquisition, the dry materials are dispersed and flattened, image acquisition is conducted again, and then high-fidelity and high-definitionimages are obtained and uploaded for analysis. Through the image acquisition unit and the sorting mechanism, higher-degree automation is realized, and the working intensity of technicians is reduced;and in addition, the problem of rock debris flattening is solved through the arranged vibration disc, high-fidelity and high-reduction rock debris surface images are provided in combination with post-processing of the intelligent camera, and the overall detection precision is improved.

Description

technical field [0001] The invention relates to the technical field of cuttings logging, in particular to a system and method for automatic detection of cuttings. Background technique [0002] In the existing technology, the real-time identification of cuttings at the mud logging site mainly relies on manual methods, that is, the cuttings samples brought out by drilling are regularly fished out of the mud, washed and dried, and judged by the naked eye of geological staff under a microscope. This traditional The current cuttings logging method has artificial subjectivity, and with the rapid development of drilling technology, the drilling speed is getting faster and faster, and the cuttings particles are getting finer, so the efficiency of manual identification cannot meet the logging requirements in the new situation. Because of this, cuttings imaging technology has gradually emerged in the domestic mud logging field in recent years. At present, most of the cuttings digital...

Problems solved by technology

[0003] Chinese patents CN201826835U and CN201522431U both disclose rock debris image acquisition devices, including the design of light source and stage, forming professional image acquisition equipment, combined with high-resolution camera / camera under the illumination of white light and fluorescent light source, it can better feedback rock debris. However, the above-mentioned technical solutions are not highly automated and lack the link of dry and wet judgment, which increases the manual workload of detection and analysis, and traditional cameras and light sources cannot provide good resolution and efficient discrimination speed

Chinese patent CN110873705A adopts the method of fluorescence combined with electron microscope scanning, combined with the lifting mechanism to improve the image acquisition accuracy and image information content, but this method still does not solve the problem of automation
