DEVICE FOR STUDYING PHYSICAL AND MECHANICAL PROPERTIES OF ROCK SAMPLES

摘要

FIELD: oil and gas industry, possible use for measuring physical and mechanical characteristics of circular rock samples with a through hole.;SUBSTANCE: device contains a thick-walled cylindrical body with circular cover made of elastic material placed in the body, which is also provided with a lid with an axial aperture, held on the body, and also a bottom, made with an aperture, and a choke positioned on the cylindrical part of the body. Device is provided with controllable pressure source and movement meter. Body bottom is made in form of flange mounted on the body and having an axial aperture, an insert in form of a disk with a tail is placed in the body. Part of the tail is located in the lid aperture, and its end is provided with a stop interacting with movement meter mounted on the frame held on the bottom of body. Body, bottom and body lid, elastic cover and insert together form a hermetic cavity connected to the controllable pressure source through the choke.;EFFECT: expanded functional capabilities, increased precision of measurements.;2 cl, 1 dwg
