The present invention provides a rock core pressurization saturation apparatus and an operation method thereof. The rock core pressurization saturation apparatus comprises: a liquid storage tank and a rock core chamber; a vacuum pump connected to the liquid storage tank through a first pipeline and connected to the rock core chamber through a second pipeline, wherein the first pipeline is provided with a first valve, and the second pipeline is provided with a second valve; a pressurization pump connected to the liquid storage tank through a third pipeline and connected to the rock core chamber through a fourth pipeline, wherein the third pipeline is provided with a third valve, and the fourth pipeline is provided with a fourth valve; and a control system respectively connected to the first valve, the second valve, the third valve and the fourth valve. With the technical scheme of the invention, the problems of the complex operation of the rock core pressurization saturation apparatus in the prior art is solved.
Description
technical field [0001] The invention relates to the technical field of geological exploration experimental equipment, in particular to a core pressurization and saturation device and an operating method thereof. Background technique [0002] In geological exploration and development experiments, core evacuation and saturation devices are widely used in reservoir rock sample experiments, mainly in porosity, seepage, physical model and other experiments, and evacuation and saturation are an indispensable pretreatment process for samples. The original evacuation and saturation device has no automatic operation interface, and cannot realize automatic pressurization. Each operation step needs to be manually operated by the operator, which increases the workload of the operator in daily work. The above situation makes the use of the core evacuation and saturation device complicated in the prior art. Contents of the invention [0003] The main purpose of the present invention is...
