The article stated that technogenic abnormal high pressure appears after the technological processes connected with the descent and clamping of the liners. Therefore, this article attempts to examine the hydrodynamic conditions of abnormal high technogenic pressure after descent and clamping of the liners (“shank”) and the causes leading to the complications during wells drilling. The recommendations are given on the choice of the well structure and the procedure of determining the liner length, ensuring the prevention of complications during the manifestation of abnormal high technogenic pressures.
