Abstract
This invention relates to the field of reservoir enhancement and stimulation in oil exploration and development, specifically to a visual experimental device for phase change proppant and its usage method. The experimental device includes a water tank connected to a constant flow pump, which is connected in parallel to a first piston container and a second piston container. Both the first and second piston containers include a first connection port, a second connection port, and a third connection port. The first connection port of both the first and second piston containers are connected to the constant flow pump. The second connection port of the first piston container is connected to one of its inlets, and the second connection port of the second piston container is connected to the other inlet. A reservoir model is also placed between the first and second piston containers. This invention has a simple structure, is highly practical, and allows for adjustable and controllable flow rate, temperature, and pressure. It can simulate and observe the phase change process of phase change proppant under different reservoir conditions and construction scenarios.
