STAND FOR THE STUDY OF HYDROMECHANICAL CHARACTERISTICS OF WELL FILTERS Russian patent published in 2022 - IPC E21B43/08 G01M99/00 

FIELD: testing equipment.

SUBSTANCE: invention relates to testing equipment, in particular to devices for testing downhole filters of various types of design used for the production and storage of hydrocarbons in the oil and gas industry. The device includes a test chamber with top and bottom covers at the ends, covering the upper and lower ends of the test chamber, respectively, serving as both the inlet of the working fluid and the outlet of the waste fluid from the test chamber, depending on the direction of fluid movement, the test filter installed in the test chamber, a pumping unit, a container for preparing a working fluid, in the upper part of which an electric motor with an agitator on the shaft is installed, a container with flushing liquid, a container for the waste liquid, pressure sensors installed at the ends of the test chamber, and equipped with shutoff valves, the first, second and third pipelines for supplying the working fluid, the first, second and third pipelines for removing the working fluid, the first and second pipelines made with the possibility of supplying the working fluid to the test chamber or removing the waste fluid from the test chamber, the pipeline for supplying the flushing fluid and the first and second pipelines for draining the waste fluid.

EFFECT: extended functionality of the stand, which consists in the possibility of testing borehole filters in conditions typical both for vertical wells and for horizontal and directional wells.
