Study of the stress strain of rock massif in the crooked wellbore

Chernova M, YE, Kuntsyak Y. V.

Vol. 31, no. 4

We investigated the stressed-deformed state of rock mass in a deviated borehole. There were received the analytical dependencies for the determination of circular and radial stress that allows for a science-based approach to the design of a borehole profile during the drilling process in the uneven horizon of rock mass of such reservoirs as Dnipro-Donetsk Depression and Black Sea Shelf and the construction of hydroacoustic directional energy devices with controlled parameters.
