CORE HOLDER FOR PHYSICAL MODELING OF MASS TRANSFER PROCESSES IN THE STUDY OF OIL DISPLACEMENT BY GAS Russian patent published in 2022 - IPC G09B23/40 G01N15/08 

FIELD: oil and gas technologies.

SUBSTANCE: claimed device relates to the field of experimental studies of mass transfer processes during filtration of oil with gases on a bulk disintegrated core model of a reservoir bed in a laboratory. The core holder consists of a base, side covers, while the side covers are made tightly adjacent to the base on both sides with bolted connections; a soft metal sealing gasket is placed between the base, the left cover and the right cover; on both sides of the base there are internal spiral channels, left and right, in the central part of the base there is a through passage channel for connecting two spiral channels by means of a bolt-nut connection; at the base of the core holder there is a through hole with the possibility of supplying an injection agent, and in the right spiral channel there is an opposite hole with the possibility of oil and gas output.

EFFECT: possibility of regulating the permeability range by means of the possibility of adjusting the tightening force of the side caps of the core holder.
