FIELD: measurement equipment.
SUBSTANCE: solution of a clayey material is injected via a sample of a porous medium. Upon completion of injection they grind a part of a sample into powder, and elutriation of the clayey fraction from the produced powder is carried out. X-ray crystal analysis is carried out on the elutriated clayey fraction, and the weight concentration of clayey material is determined in the sample of the porous medium.
EFFECT: provision of the possibility to measure low weight concentration of a clay material that penetrated pore space in process of injection of a clay-containing solution.
