Device for petrophysical studies of cores

摘要

The invention relates to the field of study permeability reservoirs of oil and gas and is aimed at reducing the time of the experiments and increase its functionality.;This is achieved in that according to the known devices comprising a core holder with mounted therein a rubber cuff test sample thermostat that provides a more constant temperature in the sample, plunger pumps that supply the sample oil and water at a reservoir pressure, a pump to create rock pressure, pipelines for supplying and removing the working fluid from the valves, the regulator back pressure, containers with liquids, volumetric flask, to measure the liquid level at the output of the core holder, pressure sensors, differential pressure gauge to measure the pressure drop across the sample and the overflow pipe with valve connecting the inlet conduit to the outlet, the device further comprises two valves mounted respectively on the inlet and outlet of the core holder between itself and core holder places bypass conduit connecting the inlet and outlet pipes for removing core holder on the hydraulic system of the device.;The utility model will expand the functionality of the device by carrying out experiments on the displacement of oil and increase the productivity of research by reducing time to disable the core holder from the hydraulic system of the device and can be used in solving a large number of tasks geopromyslovyh.
