   Смесимость во многом определяет эффективность газового воздействия. Режим смешивающегося вытеснения позволяет достигнуть максимальной эффективности. Минимальное давление смесимости (МДС) является ключевым параметром, определяемым при обосновании газового воздействия. Для условий Восточной Сибири точность прогноза на основе корреляционных уравнений составляет 10–50 %, наиболее близкие значения получены при использовании уравнения А. М. Маклавани, Х. М. Себастьяна и М. Донга. Уравнение состояния, настроенное на результаты рутинных исследований, оценивает МДС с погрешностью до 30 %. Эксперимент по набухаемости (swell test) повысил точность прогноза до 10 %. Метод исчезающего межфазного натяжения (МФН) как экспресс-метод определения параметра смесимости показал высокую точность прогноза МДС. Метод дает дополнительную возможность описания процесса изменения МФН с ростом давления или изменения состава газа и дополняет процесс адаптации уравнения состояния при настройке эксперимента в тонкой трубке.

   Miscibility largely determines the performance of gas injection. Miscible displacement allows achieving maximum effect. The minimum miscibility pressure (MMP) is a key parameter, which is determined when justifying a gas injection project. For the conditions of East Siberian reservoirs, the accuracy of correlation equations is 10-50 %, and A. M. Maklavani, H. M. Sebastian, and M. Dong equations demonstrate the most accurate values. The equation of state matched to the results of routine studies evaluates the MMP with an error of up to 30 %. Additional data from special studies (swell test) increased the estimating accuracy by up to 10 %. An express laboratory method for measuring the miscibility parameter (a method of vanishing interfacial tension) showed high accuracy of MMP estimate. The method also allows describing the process of changing the interfacial tension with increasing pressure or changing the gas composition, and complements the process of adjusting the equation of state when setting up a slim tube experiment.
