FACILITY FOR EVALUATION OF COEFFICIENTS OF RESIDUAL WATER SATURATION AND REPLACEMENT OF NON-MIXING FLUIDS IN ROCK Russian patent published in 2010 - IPC G01N15/08 

FIELD: machine building.

SUBSTANCE: facility for evaluation of coefficients of residual water saturation and replacement of non-mixing fluids in rock consists of hollow case with pressure tight cover; in case there is installed bush sleeve for sample placement connected to feeding and receiving puncheons; facility is also equipped with cartridge-trap. Notably, by means of a tail piece the receiving puncheon communicates with an axial channel and an end capillary of controlled cross section; the end of the tail piece is positioned in the cartridge-trap, while the receiving and feeding puncheons are interconnected by means of the channel. Additionally, the receiving puncheon has a lug in an upper part, a collar in a middle part and recesses for a wrench in a lower part. The said hollow case has internal side conic surface; the case is coupled with the receiving puncheon by means of thread on external side surface and a sleeve nut. The said collar is conjugated with lower ends of a thrust ring and a bushing put on the upper lug of the receiving puncheon; the bushing is equipped with an axial orifice of a conic shape in its upper part. An upper edge of the said thrust ring is conjugated with a lower edge of the sleeve. The upper part of the tail piece is equipped with a spring-loaded head including a cylinder collar and conic surface conjugated to conic surface of the bushing. An upper end of the spring is conjugated with a lower end of a cylinder collar of the tail piece head; while its lower end is conjugated with an upper end of the threaded bushing conjugated with threaded surface on an internal upper part of the cavity of the receiving puncheon. The upper end of the bushing for sample placement has conic side surface and is conjugated with the lower end of the case lug.

EFFECT: upgraded accuracy of measurements, and simplification of facility design simultaneously facilitating research of samples of various types of rock.
