FIELD: drilling of oil and gas wells. SUBSTANCE: rig includes drill bit, downhole motor, diverter, sub placed above it housing measurement module and power supply unit, drill pipes. In addition rig has shortened diamagnetic drill pipes, sub comes in the form of shortened diamagnetic drill pipe made heavier and is positioned between shortened diamagnetic drill pipes of heavier weight. EFFECT: raised operational efficiency thanks to elimination of effect of magnetic interference on readings of measurement module. 3 cl, 2 dwg
