Study on sand particle transport characteristics below the screw pump in a sand producing oil well based on laboratory experiments and numerical simulations

Progressing cavity pumps (PCPs) are widely utilized in sand-producing wells in the northern Zhaqi Oilfield due to their sand-carrying capability. However, when sand volume increases, sand particle diameter enlarges, or formation pressure significantly decreases, their sand-carrying capacity graduall...
