Optimization methods of drilling hydraulics in deep wells
In article ways of deep oil and gas well hydraulic program’s optimization are described. Necessity of transition from traditionally used standard sizes of 127 mm drill pipes to new types of drill pipes – 139,7 mm with double shoulder connection is established. Advantages of application of such pipes are shown: decrease in total hydraulic losses inside pipes and annulus on 30-60 %, increase in durability of drill string on a pipe body on 10 %, increase in stiffness of pipes on 36 % that raises resistance to a sinusoidal and helical buckling.
