METHOD, APPARATUS AND SYSTEM FOR ESTIMATION OF ROCK MECHANICAL PROPERTIES

摘要

An apparatus for measuring mechanical properties of a rock formation. The apparatus includes force application fixtures configured to apply opposing compressive forces to a disc-shaped sample of a core plug specimen from the rock formation. Each of the force application fixtures include an applicant portion having an end cap. The end cap has a shaped surface that is configured to conform with a portion of a non-planar side of the disc-shaped sample such that substantially an entire volume of the disc-shaped sample experiences a compressive stress when the opposing compressive forces are applied to the portions of the non-planar side. A system and method for measuring mechanical properties of a rock formation are also disclosed.
