FIELD: oil and gas production.
SUBSTANCE: drilling procedure on base of mechanical specific energy (MSE) consists in drilling in first interval, using first workload on bore bit (WOB), in automatic determination of first MSE, corresponding to drilling, using first WOB, in drilling in second interval, using second WOB, different from first WOB, in automatic determination of second MSE, corresponding to drilling, using second WOB and drilling in third interval, using one of first WOB and second WOB chosen automatically on base of automatic comparison of first MSE and second MSE.
EFFECT: upgraded accuracy of determination of working characteristics of drilling machine.
