Sand production simulation experimental device
Sand production simulation experimental device
Artificial sand is configured based on the distribution data of formation core (PSD). The artificial sand is vertically loaded on the core machine according to the cementation strength of the formation rock to form an artificial core. The artificial core is placed in the experimental evaluation device to simulate the formation core layer, gravel layer, and casing wall of the oil and gas well, and the experimental oil is displaced outside the "artificial wellbore".
Achieve the detection of anti-clogging, reverse circulation washing acid washing, and sand production of various combinations such as perforation, bare hole, sand screen prevention, and gravel filling prevention of screen pipes with different sand prevention media under the condition of liquid production speed;
Evaluate the sand prevention effect and process of full-size screen pipes;
Optimize different sand prevention screen pipes.
