Introduction
Well logging is the process of keeping a thorough log of drilling holes' formation. This includes bringing samples to the surface for in-person examination as well as taking physical measurements with equipment inserted into the wellbore. At various drilling engineering stages, including drilling, completion, production, and abandonment, logging can be done. Drilling for oil and gas, groundwater, minerals, and geothermal exploration, as well as environmental and geotechnical research, is done through logging.
Problems with geology of mineral resources, engineering, natural disasters, and the environment's ecology can all be solved with geophysical logging. It is a contingent and oblique reflection of the drilling's actual geological circumstances. Further processing is required to transform the logging data into geological, engineering, disaster geology, and ecological environment data. We can only see the value of identifying and fixing problems with information.
A digital logging system called GDQ - 2D, which can be connected to many types of pipe and log, was created specifically for the convenience of field work. Because of the advanced technology used by this system, it improves the use of a single ground-based instrument managing a single heavy logging probe into a single ground-based instrument controlling multiple logging probes, as well as deep measurement, power supply, and other features. The instrument is lightweight, easy to use, and maintain. It can be attached to a tube type that is very reliable, aseismatic, temperature-resistant, and moisture-proof.
