FIELD: mining industry.
SUBSTANCE: invention relates to a device and method for studying the effect of coke deposits on the physical properties of the formation. The device for studying the influence of coke deposits on the physical properties of the formation includes: a saturation system, a measurement system and a coking system, as well as a device for cleaning coked core samples. The saturation system contains a core holder, the inlet section of which is located parallel to the oil storage tank and the water storage tank. The core holder is connected to an overpressure pump. The measurement system includes a core gas permeability and porosity analyzer, a 3D NMR analyzer and a computer tomograph. The coking system contains at least two coking chambers. The coking chambers are at least one coking chamber for high-temperature pyrolysis and at least one coking chamber for oxidation. The coking chamber for high-temperature pyrolysis is connected to a nitrogen storage tank. The coking chamber for oxidation is connected to an air storage tank. The method for studying the influence of coke deposits on the physical properties of the formation includes: taking core samples, assessing permeability and porosity, observing and registering the internal structure of cores; saturation of cores with oil; placing cores after saturation into the coking chambers to carry out the coking reaction; cleaning of coked core samples; assessing the permeability and porosity of cleaned cores; observing and registering the internal structure of the pore channels of cores; determining the influence of coke deposits on the physical properties of the formation.
EFFECT: simplicity of the design, simplicity of the experiment and its easy control, high accuracy and low error of the experiment compared with the study of the influence of coke deposits on the physical properties of the formation in traditional tubular combustion chambers.
