Abstract
Apparatus is provided for performing mechanical deformation studies of a sample of material to determine mechanical and petrophysical properties of such a sample. The apparatus is useful in conjunction with an imaging (NMR or CAT) apparatus.
Claims1
Apparatus for containing a sample, comprising:
- outer tubular member having engaging means at each extreme end and an interior opening therethrough,
- first end member disposed partially in said tubular member and sealingly contacting said interior opening,
- second end member disposed partially in said tubular member and sealingly contacting said interior opening and having a projection thereon,
- first and second ring members for releasably engaging said engaging means of said tubular member and fixedly restraining said end members in said tubular member,
- piston means disposed in said tubular member operating in conjunction with said second end member for providing uniaxial forces on such a sample and having a projection thereon,
- pressure transmitting member sealingly disposed around such a sample, said projection of said second end member, and said projection of said piston means,
- means for applying pressure to said pressure transmitting member, and
- means for moving said piston means.
