FIELD: oil and gas industry.
SUBSTANCE: invention can be used to simulate the processes of colmatation and decolmatation of the bottomhole zone of a well in laboratory conditions. A complex for modeling colmatation and decolmatation of the bottomhole zone of a well is claimed, which includes a core compression line, a pressure gauge, a physical model of the bottomhole zone of the well, a stand of the physical model of the bottomhole zone of the well, and a laboratory pump. At the same time, the complex is additionally equipped with an emitter head of a physical model of the bottomhole zone of the well, containing a filtration channel for supplying a working fluid and an ultrasonic emitter, a receiver head of a physical model of the bottomhole zone of the well, containing an ultrasonic receiver, piston containers with flushing fluid, a piston container with diluted acid, acid piston container, large volume piston container, liquid and solid trap, gas source, laboratory gasometer, piping including gas supply line, gas control line, high pressure line, working fluid supply line, purge line.
EFFECT: increase of variability of possible types of impact on the core material.
