FIELD: oil and gas industry. ^ SUBSTANCE: test method of operability of hydromechanical generators and bench for objective evaluation of wave action of pressure oscillations on oil displacement from productive formation model is described. Method consists in pumping of the whole volume of displacement fluid through the main line of the bench, in which there installed in series is oscillation generator with electric drive, productive formation model with oil content and graduated measuring cylinder for collection of additional amount of displaced oil. Method allows carrying out the tests of flow-through hydrodynamic generators of pressure oscillations in fluid flow, and interruption of fluid pumping through generator shall be performed by means of electric drive. The new feature is pumping of the whole volume of displacement fluid through the interrupting generator assembly. The bench includes the following: forced fluid supply system, main line with pressure sensors and pressure pulsations; pressure oscillation generator and model of productive formation, which represents hollow cylinder filled with porous medium containing residual oil; in the main line of the bench there installed in series is pressure oscillation generator and formation model, and pressure oscillation generator has electric drive which is connected through reduction gear to the shank of rotating shaft; at that, formation model is installed horizontally. ^ EFFECT: possibility of carrying out the bench tests of flow-through hydromechanical generators of pressure oscillations in fluid flow, and interruption of fluid pumping through generator shall be performed uniformly by means of electric drive. ^ 2 cl, 1 dwg |
