FIELD: oil and gas industry. ^ SUBSTANCE: device includes the equipment for measurement of parametres of drilling or coring process which is performed by means of the bit attached to the end of drilling column. Measurement equipment is placed into the chamber made in the coupling which is arranged between pipes of drilling column or between the bit and pipe of the drilling column, or contains reducer of the cutting head of the bit of drilling column. At that, coupling is cylindrical, and chamber includes the cavity made along the coupling periphery. At that, the above equipment is included in the drilling and/or coring unit, which includes the bit and drilling column. ^ EFFECT: improving accuracy of measurements with simultaneous simplification of the device and reduction of its cost. ^ 24 cl, 7 dwg |
