METHOD FOR DETERMINING WATER SATURATION OF CORE SAMPLES

摘要

FIELD: technological processes.;SUBSTANCE: invention relates to a method for determining current water saturation of uniform sandstones on a centrifuge without stroboscopic device. According to the method, core is sampled and samples of cylindrical shape are made. Perform extraction of hydrocarbons from it, drying, weighing in air and saturation with working fluid. Determine mass before and after centrifuge process. At the same time, before saturation of samples, their permeability is determined and duration of rotation of the centrifuge rotor is calculated for current value of capillary pressure. Samples are saturated with working fluid, mass is determined before and after centrifuge process.;EFFECT: technical result is to accelerate process of investigation of rock samples and differentiated determination of current water saturation of samples by centrifuge process, taking into account filtration parameters of a single sample.;1 cl
