HOLDER OF POROUS IMAGES, SYSTEM AND METHOD FOR THEIR EXAMINATION Russian patent published in 2023 - IPC E21B49/00 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to means for studying the filtration properties of rocks and can be used in the oil and gas industry. In particular, a porous sample holder is claimed, filled with hydraulic fluid and containing at least one cuff located inside the holder body, into which at least one porous sample is placed. In this case, the cuff with the sample is limited on both sides by a pressure supply device, and the body is limited on both sides by flanges in such a way that at least one of the flanges is connected to a pressure supply device communicated with the holder through at least one pressure supply line and liquid supply lines through which the displacing and displaced fluids pass through a porous sample. In this case, the pressure providing device has a bayonet connection with the flanges, made in the form of at least one locking element on the pressure providing device and at least one sector groove on the flanges, complementary to the locking element. Also disclosed is a system for examining porous samples, comprising a holder for porous samples, and a method for examining porous samples.

EFFECT: increasing the efficiency of research into filtration formation processes, including by expanding the functionality of the system for studying porous samples and increasing the speed of research.
