A method for quantitative determination of saturated rock samples using the values ​​of the initial and final water saturation

摘要

FIELD: mining.;SUBSTANCE: there performed is a core sample preparation, modelling of core sample reservoir conditions, joint filtering of salt water and oil through core sample, measurement of intermediate intensiveness of X-rays passed through the sample during filtering and determination of water-saturation by expressions. Note that the intensity of X-rays passing the sample with initial and final water-saturation is measured, the reference signal is obtained. The value of residual water-saturation is obtained after filtering experiment of water evaporation from the sample at 110-160°C. The values of initial, residual water-saturation and reference signal are used for determination of intermediate water-saturation via certain mathematical relation.;EFFECT: reduction of time for core water-saturation measurement, increase of water-saturation values determination accuracy.;3 cl, 1 dwg
