DEMOUNTABLE CONTAINER FOR MOULDING SAMPLES FROM BACKFILL SOLUTIONS Russian patent published in 2020 - IPC G01N33/38 G01N1/31 

FIELD: mining.

SUBSTANCE: invention relates to a device for moulding samples from a backfill solution used in cementing oil and gas wells. Demountable container consists of bottom, cover, walls and handle fixed on cover. Walls are made double - external and internal - in the form of hollow coaxially located cylinders. External walls are made with coupled stepped ends and are connected through separator, upper surface of which is made with annular projection for interaction with slot of one external wall, and its lower surface is equipped with wall made in the form of hollow cylinder with stepped end for connection with other external wall. Walls of separator and cover are made equal to height and provided with through holes to create pressure inside container. Inserts are installed on ends of internal walls. Total height of insert wall and inner wall is less than total height of separator wall and outer wall in lower part of container, as well as outer wall and cover wall in its upper part. Bottom, cover, walls, separator and inserts have same thickness.

EFFECT: technical result is moulding two samples of similar composition, high accuracy of test results, as well as ease of manufacture and maintenance of device.
