FIELD: gas and oil production.
SUBSTANCE: device for analysis of physical properties of propping materials for hydraulic fracturing of reservoir consists of core holder wherein there is placed propping material, of system of hydraulic clamping and filtration, and of measuring reservoir for measurement of volume of liquid filtered through propping material. Propping material is placed in the core holder in a directing bush inserted into a rubber collar and a perforated metal jacket. The rubber collar is pressed to the case of the core holder by means of packing cones, while metal filters and pressing pistons are set on ends of the directing bush. Space between the metal jacket and the case of the core holder is connected with a system of hydraulic clamping facilitating side hydraulic clamping.
EFFECT: raised accuracy of analysis of physical properties of propping materials for reservoir hydraulic fracturing.
