High-precision dynamic self-orientation identification while-drilling instrument

The invention relates to the field of drilling equipment, in particular to a high-precision dynamic self-orientation identification while-drilling instrument. The orientation while drilling device comprises an orientation while drilling device main body, a storage module; the while-drilling dynamic direction adjusting mechanism comprises a cylindrical shell, a plurality of groups of top wall assemblies and a driving mechanism, wherein the interior of the cylindrical shell is hollow, and a plurality of channels are annularly and uniformly formed in the outer circumferential surface of the cylindrical shell; the top wall assemblies are uniformly distributed around a central shaft of the shell and correspondingly penetrate through the channels; the driving mechanism is used for driving the top wall assemblies to extend outwards through the channels; the ejector is configured to selectively eject the top wall assembly to the inner wall of a drilling well through the channel every time so as to adjust the drilling
