Abstract
A solid particle handling system for downhole pumps operating at low flow rates is disclosed. In one embodiment, the system includes an outer tubing, such as a production tubing, and an additional inner tubing positioned therewithin. This configuration facilitates increased fluid speed, promoting vertical movement of solid particles. A designated storage area between the outer tubing and the inner tubing accumulates particles, while a diverter optimizes fluid redirection and particle flow. In one operational mode, the fluid medium, along with solid particles, flows at an increased speed through the smaller diameter inner tubing. In another mode, accumulated particles are stored in the designated area, preventing pump blockage.
