Title
(EN) A METHOD AND DEVICE FOR FLUID DISPLACEMENT
(FR) PROCEDE ET DISPOSITIF POUR DEPLACEMENT DE FLUIDE
Abstract
(EN) A method and device for displacement of a first fluid by means of a second fluid in a borehole (1) in the ground, where, during displacement, the second fluid is kept separate from the first fluid, and where the volume of an expandable space (22) in which the second fluid is to be located following the displacement, increases during inflow of the second fluid.
(FR) Il est décrit un procédé et un dispositif pour le déplacement d'un fluide au moyen d'un second fluide dans un trou de forage (1) dans le sol, où, durant le déplacement, le second fluide est maintenu séparé du premier fluide, et où le volume d'un espace extensible (22), dans lequel le second fluide est destiné à être situé après le déplacement, augmente durant l'arrivée du second fluide.
