ІMPROVED APPROACH TO THE DESIGN AND CONSTRUCTION OF CHOICE DRILL STRING TAKING INTO ACCOUNT ENERGY
Journal Title: Молодий вчений - Year 2017, Vol 3, Issue 43
Abstract
An improved approach to the design and selection of the drill string, taking into account energy costs. Energy costs thus calculated for the conditions of rotation of the drill string in the borehole and ensure circulations in well. Takes into account indicators of equivalent, axial, bending, torsional stress, the yield point of materials, strength and geometrical factors of system, friction of metal to rock, rotating drill string in well. It is displays in a program DrillStr developed by the authors at development environment Delphi 7. Shown algorithm of calculation and selection of energy efficient drill string at a some set of alternatives.
