Abstract
Изобретение относитс к области испытани горных пород и позвол ет повысить точность определени остаточной водо- насыщенности (ОВ) горной породы путем устранени образовани вакуума в порах образца породы при вращении. Способ определени ОВ образца горной породы включает сушку образца, его насыодение водой, погружение в стакан центрифуги под уровень жидкости, не смешивающейс с водой, на критическую глубину, центрифугирование образца породы при посто нной скорости вращени с измерением объема воды, вытесненной из пор образца породы. 1 табл.The invention relates to the field of testing rocks and improves the accuracy of determining the residual water saturation (RH) of a rock by eliminating the formation of a vacuum in the pores of the rock sample during rotation. The method for determining the OM of a rock sample includes drying the sample, saturating it with water, immersing the centrifuge into a glass that is not immiscible with water at a critical depth, centrifuging the rock sample at a constant rotational speed and measuring the volume of water displaced from the pores of the rock sample. 1 tab.

Изобретение относитс к испытани м горных пород и предназначено дл определени остаточной водонасыщенности образца горной породы путем его центрифугировани .The invention relates to the testing of rocks and is intended to determine the residual water saturation of a rock sample by centrifuging it.
Цель изобретени - повышение точности 5 определени .The purpose of the invention is to improve the accuracy of the 5 determination.
Пример. Эксперимент проводитс на центрифуге типа ЦЛР-1 с радиусО1М вращени . 11,5 см. Длительность вращени во всех опытах составл ет 60 мин. Методика опре- : делени остаточной водонасыщенности об- I разцов пород по предлагаемому способу и I по способу-прототипу сводитс к следую- I щему. Образец горной породы сушат до по- I сто нного веса, насыщают его децинормальсыщенности по способу-прототипу и по предлагаемому способу показаны в таблице. Example. The experiment is carried out in a centrifuge of the type CLR-1 with a radius of O1M of rotation. 11.5 cm. The duration of rotation in all experiments is 60 minutes. The method for determining the residual water saturation of rock samples by the proposed method and by the method of the prototype is as follows. A rock sample is dried to standing weight, it is saturated with decinsorseness by the prototype method and the proposed method is shown in the table.
Водонасыщенность образцов песчаника после центрифугировани в течение 60 мин по прототипу PI 1,03 г/см, р2 Q) и по предлагаемому способу (pi 1,03 г/см , Р2 0,806 г/cм при 1 3 см, R 11,5 смХThe saturation of sandstone samples after centrifugation for 60 min according to prototype PI is 1.03 g / cm, p2 Q) and according to the proposed method (pi 1.03 g / cm, P2 0.806 g / cm at 13 cm, R 11.5 cmX
