The definition of well drilling parameters considering rocks’ anisotropy
Y.A. OrujovOn the basis of energetic strength condition, the issue of well wall steadiness during drilling considering rocks anisotropy, was reviewed. The critical value of overpressure depending on mechanical characteristics and specific weight of the rock, lying on the definite drilling depth, was determined. This parameter plays a special role in oil and gas wells drilling in a safe way.
