AI Technical Summary
In existing technologies, vibrations between the drill collar and the seabed are transmitted to the logging-while-drilling instrument, causing damage to instrument components and affecting normal use.
A logging-while-drilling instrument was designed, comprising a support assembly, a buffer assembly, and a protective casing. The buffer assembly buffers vibrations, the protective casing isolates drilling fluid, the support assembly secures the processor and battery to prevent vibration and heat transfer, and the sensor is placed in the detection groove inside the drill collar, with the signal transmitted to the processor via a transmission line.
It effectively buffers drill bit and seabed vibrations, protects the processor and battery from damage, ensures stable transmission of sensor signals, and uses a protective casing to cool the processor and battery, avoiding the influence of drilling fluid, thus improving the reliability and detection accuracy of the instrument.
