Core fluorescent light and white light integrated image acquiring system and method

Abstract

The invention belongs to the field of geological oil exploration, and relates to a core fluorescent light and white light integrated image acquiring system, which comprises an industrial personal computer, a master controller, a photographing scanner, a transverse driving device, a longitudinal driving device, a rubber covered roller device and a ranging sensor. The master controller consists of a PLC (programmable logic control) circuit and a servo controller, the photographing scanner comprises a support, a sunshade, a white light source, a fluorescent light source, a linear array CCD (charge coupled device) color camera, an area array high-resolution color camera, a camera rotating device and an internal longitudinal driving device, the linear array CCD color camera is fixed on a rotating platform of the camera rotating device, and the longitudinal driving device is connected onto the transverse driving device. The invention also provides an image acquisition method realized by the system. Core white light and fluorescent light images can be acquired fast, objectively and accurately.

Description

technical field [0001] The invention belongs to the field of geological petroleum exploration, and relates to a rock core image acquisition method and device. technical background [0002] In recent years, my country's geological undertakings have made great progress, especially the application of new technologies and methods has promoted the progress of geological scientific research. According to the survey, there are millions of meters of drilling tasks in my country every year, producing a large number of cores. Rock core is the first-hand information that geologists obtain underground geological information in oil and gas exploration and development research work. The parameters are all from cores. Under normal circumstances, after the cores are out of barrels, they are packed in boxes and placed under natural conditions for centralized storage. There are two problems: first, the volatilization and oxidation of oil and gas in the cores that have been placed for a long...

Problems solved by technology

Under normal circumstances, after the cores are out of barrels, they are packed in boxes and placed under natural conditions for centralized storage. There are two problems: first, the volatilization and oxidation of oil and gas in the cores that have been placed for a long time; second, frequent sampling, observation and description, and natural weathering, etc. Factors that affect the accuracy, integrity and authenticity of the core

[0003] Most of the core scanners in the market currently collect white light and fluorescence images independently on two devices, and the degree of automation is not high enough. The following problems exist in the separate design: first, the two devices are designed independently, It requires a lot of manpower, material and financial resources, increases the cost of equipment purchase, and does not meet the requirements of sustainable development; secondly, it increases the occupied area, and the same core needs to be scanned twice on two devices, and the image scanning efficiency not tall
