The invention discloses a high-resolution
logging-while-drilling device adopting gamma and side-scanning comprehensive imaging. The high-resolution
logging-while-drilling device adopting gamma and side-scanning comprehensive imaging comprises an outer
drill collar, wherein an upper-part wear-resistant ring is arranged at one end of the outer
drill collar, and a lower-part anti-wear belt is arranged at the other end of the outer
drill collar; an inner mandrel is arranged in the outer drill collar; a gamma
detector, a pseudosymmetric emission
electrode T3, a measurement
electrode T2, a measurement
electrode T1, a quadrant reception pole plate, a button reception electrode and a measurement electrode T4 are sequentially arranged on the inner mandrel between the upper-part wear-resistant ringand the lower-part anti-wear belt; the gamma
detector and the button reception electrode are used for
gamma imaging and resistivity imaging; the quadrant reception pole plate is used for realizing anazimuthal side resistivity measurement function; and the pseudosymmetric emission electrode T3, the measurement electrode T2, the measurement electrode T1 and the measurement electrode T4 are used forrealizing different depth-sounding resistivity measurements. The high-resolution
logging-while-drilling device adopting gamma and side-scanning comprehensive imaging is reasonable in structural
layout, high in reliability, simple to
machine, and convenient to maintain and extend.
