Abstract
1. Способ определения дисперсности водогазовой смеси под давлением, включающий получение водогазовой смеси под повышенным давлением, отбор пробы водогазовой смеси и перевод ее в измерительную емкость при том же давлении, отличающийся тем, что перед проведением измерения определяется объем измерительной емкости, а в процессе измерения непрерывно регистрируется изменение давления свободного газа внутри измерительной емкости и объем свободного газа, соответствующее ему приращение объема свободного газа, определятся общее количество газа, содержащегося в отобранной пробе, затем определяется зависимость ΔР от объема свободного газа в емкости, которая затем пересчитывается в зависимость изменения давления (ΔР) от относительной доли текущего значения массы свободного газаm/m,где m- общее количество газа m, содержащегося в отобранной пробе;m- текущее значение массы свободного газа,далее определятся радиус газовых пузырьков, содержащихся в доли текущего значения массы свободного газа, по формуле,где σ - межфазное натяжение,и вычисляется функция распределения радиуса пузырьков.2. Способ по п.1, отличающийся тем, что количество газа, содержащегося в объеме рассчитывается по уравнению Менделеева-Клайперонагде n- количество молей газа;R - универсальная газовая постоянная;Т - абсолютная температура;Р-начальное давление газа в измерительной емкости;ΔP- прирост давления;ΔV-увеличение объема газа.3. Способ по п.1 отличающийся тем, что общее количество газа m, содержащегося в отобранной пробе, рассчитывается по уравнениюm=Mn,где М - среднее значение молекулярной массы закачиваемого газа, а n-количество молей газа в пробе,4. Спо�1. A method for determining the dispersion of a water-gas mixture under pressure, including obtaining a water-gas mixture under increased pressure, sampling a water-gas mixture and transferring it to a measuring vessel at the same pressure, characterized in that the volume of the measuring vessel is determined before the measurement, and continuously during the measurement the change in the pressure of free gas inside the measuring vessel and the volume of free gas corresponding to it, the increment of the volume of free gas, the total for contained in the selected sample, then the dependence ΔР on the volume of free gas in the tank is determined, which is then converted into the dependence of the pressure change (ΔР) on the relative fraction of the current value of the mass of free gas sample; m is the current value of the mass of free gas, then the radius of the gas bubbles contained in a fraction of the current value of the mass of free gas is determined by the formula, where σ is the interfacial tension, and the distribution function of the radius of the bubble is calculated B.2. The method according to claim 1, characterized in that the amount of gas contained in the volume is calculated according to the Mendeleev-Klaiperonagde equation n is the number of moles of gas; R is the universal gas constant; T is the absolute temperature; P is the initial gas pressure in the measuring vessel; ΔP- pressure increase; ΔV-increase in gas volume. 3. The method according to claim 1, characterized in that the total amount of gas m contained in the selected sample is calculated by the equation m = Mn, where M is the average molecular weight of the injected gas, and n is the number of moles of gas in the sample, 4.
