Drilling String

While drilling oil and gas wells, 10–15 % of open part of wellbore consists of permeable fractured reservoirs and horizons. Despite of it, 70–80 % of failures occurring in wellbore fall on the permeable suites. After sticking electrical measurement only upper interval is specified. Then an oil patch is practically installed in abnormally complicated reservoirs in the upper permeable stuck and bottomhole intervals to prevent the complications and blowout. The drilling string often remains stuck beneath the upper suite in three-four suites to the bottomhole. It is necessary to install stepped oil bath to prevent it.

Resistance Forces

When drilling deep oil and gas wells with large deviations from the vertical stope the resistance when moving the drill string in borehole significantly increases. A consequence of this is the difficulty of control screw steerable motor. Minimizing resistance forces is possible through usage of a J-shaped profile. The authors present the technique and results of calculation of layout, ensuring reliable integration of the trajectory of the well. This is achieved through the contact link to the bottom of the borehole wall in four locations, including a chisel, curved subs and two pillars.
