... керна, является определение фазовых проницаемостей нестационарными или псевдостационарными методами. For the first time it was discovered that while defining relative phase permeability with the method of a joint steady-state filtration there takes place a core draining within the process of a steady-state filtration. It causes errors in definition of relative phase permeability. Materials and methods OST ...

... получить функцию ОФП уже после двух измерений, а дополнительные измерения повышают ее точность. The proposed method allows reducing time of laboratory experiments for relative phase permeability determination. The result is a consequence of determination of pseudo-steady filtration. Pseudo-steady filtration means very weak alteration of filtration flows which make it possible to do reliable measurements of permeability ...
