In mid-October, the core permeability damage flow experimental device invented by Dagang Oilfield Exploration and Development Research Institute obtained the national utility model invention patent.
For a long time, the high-pressure vessels of domestic core flow experiment instruments are combined and connected in a simple parallel manner. Each high-pressure vessel is equipped with a different experimental fluid and works independently without affecting each other. During operation, the injection volume of the core flow experiment fluid is limited by the volume of the high-pressure container itself, which is prone to fluctuations during the experiment.
Researchers at the Dagang Oilfield Exploration and Development Research Institute invented the experimental device for the core permeability damage flow. This device has changed the connection of several high-pressure vessels in parallel in the past. It is composed of high-pressure displacement pumps, ring pressure pumps and three-way ball valves. It can connect each high-pressure vessel in parallel and inject different experimental fluids to work independently. Multiple high-pressure vessels with the same experimental fluid are connected in series to form a unit, or several serial units with different experimental fluids are connected in parallel to increase the volume of the experimental fluid exponentially to meet the requirements of different injection volume core flow experiments .
