Abstract

Virtually allmodern gas and oil production technologies are based on directional drilling, and hence well stability issues are of primary importance. It was established that the stability of slanted wells significantly depends on the deformation and strength characteristics of rocks, on the presence and degree of rock anisotropy, and also on the well geometry and the pressure at the well bottom. We suggest a new approach to this problem by modeling the hole making process with the use of a triaxial independent loading test system (TAILTS) based on the mechanical-mathematical model developed here.
