Title
(EN) DEVICE FOR PERFORMING THERMODYNAMIC MEASUREMENTS ON MULTIPHASE FLUIDS AT VERY HIGH PRESSURES AND TEMPERATURES
(FR) DISPOSITIF POUR FAIRE DES MESURES THERMODYNAMIQUES SUR DES FLUIDES POLYPHASIQUES A TRES HAUTES PRESSIONS ET TEMPERATURES
Abstract
(EN)
The fluids to be studied are placed in a chamber (13) of variable volume delimited by a piston (5) which is displacable by hydraulic means (24) within the cavity of a body (1). Behind a transparent window (8) closing the end of the chamber opposite the piston, an endoscope (18) is placed for viewing the chamber interior and, in particular, the openings of two diametrically opposite ducts (14, 15) which link the enclosure to the exterior. The body (1) can pivot about an axis (26), thereby enabling a given stratified multiphase fluid phase to be balanced and sampled, by having the opening of one of the ducts (14, 15) placed within the phase. A pressure sensor (18) is incorporated into the wall itself of the piston so as to reduce virtually any of the lost volume capable of distorting the measurements. A single body can contain two enclosures arranged side by side, at least one having a transparent wall. The device of the invention is for studying fluids, especially petroleum fluids.
(FR)
Les fluides à étudier sont placés dans une chambre (13) de volume variable délimitée par un piston (5) qui est déplaçable par des moyens hydrauliques (24) dans une cavité d'un corps (1). Derrière un hublot transparent (8) fermant l'extrémité de la chambre opposée au piston, est placé un endoscope (18) permettant de visualiser l'intérieur de celle-ci et notamment de voir les orifices de deux conduits (14, 15) diamétralement opposés qui font communiquer la cellule avec l'extérieur. Le corps (1) peut pivoter autour d'un axe (26), ce qui permet une mise à l'équilibre et aussi le prélèvement d'une phase particulière d'un fluide polyphasique stratifié, ceci en plaçant l'orifice de l'un des conduits (14, 15) au sein de cette phase. Un capteur de pression (19) est intégré dans la paroi même du piston de façon à diminuer pratiquement tout volume mort susceptible de fausser les mesures. Un même corps peut contenir deux cellules disposées côte à côte, l'un au moins ayant une paroi transparente. Application à l'étude de fluides, notamment de fluides pétroliers.
