Estimation of hydraulic resistances at pneumatic impact drilling with foam

Abstract
The development of a methodology for calculating the depth of pneumatic percussion drilling with the use of gas-liquid cleaning agent seems to be very important for the correct assessment of the possibilities of pneumatic percussion drilling and determination of rational modes of supplying gas-liquid mixture (GMS), providing the maximum energy parameters of the pneumatic percussion at minimum pressure losses in the well.
