Abstract
A rod centralizer and solids control assembly can be mounted on a rod string. The assembly allows well fluid containing high solids to pass through the pump while eliminating the solids from being swept back into the pump barrel or accumulating in the tubing. The assembly can include a body portion coupled to a bristle positioned helically around the body portion. The bristle can be coupled to a piston, allowing the bristle to extend during upward fluid movement and retract when rod rotation stops. The bristle can trap solids, leaving the solids higher and away from a pump intake. This can allow the solids to be lifted out of the pump, preventing solids from collecting on a bottom portion of the pump or tubing. The assembly can include centralizer components that center the rod, preventing it from rubbing against the tubing. Multiple assemblies can be incorporated into the rod string.
