Intelligent drilling television imaging instrument

Abstract

The invention relates to an intelligent drilling television imaging instrument, which mainly consists of a main controller, an underground probe, an underground cable, a windlass, a hub, a stepper motor, a depth counter and a tripod. The main controller is used for collecting and storing the information such as image splicing, video, depth and azimuth angle; the underground cable is used for supplying power to the probe and transmitting a control order, video, angle and the like; the underground probe is used for shooting a picture and video and recording the underground azimuth angle and transmitting the information to an industrial control computer through the cable; the depth counter is used for recording the underground depth of the underground probe; the stepper motor is used for controlling the probe to ascend and descend at a constant speed. An open-type lens is directly arranged in the water, and no glass cover is arranged in front of the lens, so that a shot image of a well wall is clearer, and the color retention is more authentic; a combined-type light source is adopted, so that the well wall and the underground situation can be directly observed; by adopting the unique stepper motor and the depth counting hub device, the probe can be lowered and lifted at a constant speed, and the images are completely spliced; by introducing electronic rock core library software, an electronic rock core file is established.

Description

technical field [0001] The invention relates to an intelligent borehole TV imager, which belongs to geophysical exploration equipment and is suitable for engineering geology, hydrogeology, geological prospecting, geotechnical engineering, mines and other departments; it is suitable for vertical holes, horizontal holes and inclined holes (depression angle , elevation angle), anchor cable (rod) holes, geological drilling and concrete drilling and other types of drilling. Form digital drilling panorama pictures and videos, and finally summarize them into a digital core library to store the data permanently. The present invention is especially suitable for fracture zone formations where actual rock cores cannot be obtained. It is used for observing the wall conditions in various boreholes and observing various characteristics and fine structures of geological bodies in boreholes, such as stratum lithology, rock structure, and faults. , fissures, interlayers, karst, ore body ore t...

Problems solved by technology

However, due to factors such as unreasonable light source design and insufficient light source brightness, fogging of the lens glass protective cover, depth error and inaccurate image splicing caused by manually lowering the probe, the obtained image data is not clear enough. The color of the image is distorted and the image resolution is not enough, which affects the analysis of drilling data and the accuracy of survey results; at the same time, this type of in-hole TV probe does not have both in-hole video and full-hole wall imaging modes, which is difficult for on-site data acquisition. It brings great limitations; in the end, digital data such as images and videos detected by this type of borehole TV imager fail to form an electronic core library, which is not convenient for browsing, archiving, and retrieval of borehole electronic data. inconvenience to researchers
