Abstract

A procedure for calculating the pressure and power of a mud pump used in drilling an extendedreach well is described. A method is proposed for determining the hydraulic extension limit length in the drilling process depending on the rated pressure and power of the pump. An example is given of maximum well depth calculation with allowance for the limitations of a specific pump having fixed characteristics.
