Description

Technical Field

[0001] The utility model relates to the technical field of geophysical directional logging instruments, in particular to a downhole geophysical directional logging instrument. Background Art

[0002] The geophysical directional logging instrument is mainly composed of four parts: the probe, the host control box, the host control panel and the push rod. The probe is mainly composed of a high-definition camera, natural gamma, apparent resistivity, natural potential, induced potential 1, 2, drilling trajectory measurement and control unit. When measuring large-diameter boreholes, by setting a centralizer, it can ensure that the probe is located in the center of the borehole during detection. When it is used, it is based on underground coal mine drilling, and completes the collection of borehole logging data (natural gamma, apparent resistivity, natural potential, induced potential), borehole peek video, borehole trajectory data (borehole azimuth, inclination) and borehole depth data at one time. Special data analysis software is used to perform lithology stratification based on the change law of logging data (natural gamma, apparent resistivity, natural potential, induced potential), generate borehole columnar graphs and borehole trajectory graphs, and conduct comprehensive stratigraphic feature analysis in combination with geological data, and analyze the structural development of faults, collapse columns, fissures, water outlet characteristics and roof delamination conditions.

[0003] The existing geophysical directional logging instrument has a high-definition camera directly installed at one end of the push rod. When in use, it has the following shortcomings: 1. There is a lack of a structure to protect the high-definition camera. When moving in the borehole to collect data, there is a risk of being damaged by collision with stones or soil in the borehole; 2. Since there is a lot of mud in the borehole, the mud and dust of the high-definition camera are easily attached to the monitoring end of the high-definition camera during the monitoring process. The dust cannot be automatically cleaned at a regular interval, which affects the monitoring clarity and cannot meet the use requirements. Based on the above situation, we propose a downhole geophysical directional logging instrument. Utility Model Content
