Abstract

For some wellbore cleanup tools (“WCT”), the light debris are difficult to collect since they are not easy to settle down in WCT's debris chamber. Besides, since they are not easily settle down, they will be going up with the flow and may choke the screen, which will lower the efficiency of the WCT.

"Silencer" Debris Collector

For some wellbore cleanup tools (“WCT”), the light debris are difficult to collect since they are not easy to settle down in WCT's debris chamber.   Besides, since they are not easily settle down, they will be going up with the flow and may choke the screen, which will lower the efficiency of the WCT. 

In this invention, a "Silencer" (i.e.  muffler) like debris collector is proposed to collect the light debris more efficiently.  Instead of using just one "bird house" to create turbulent flow and help settle the debris for a conventional WCT debris collector, the "Silencer" design makes use of multiple tilted plates inside a tubing to induce vortex that can help sweep the light debris to the corners and then fall down to the bottom of the collection chamber throughout the slots at the corners.  Through the multiple tilted plates inside the central tubing, the energy of the incoming slurry flow can be reduced greatly will can help create better vacuum effect.  The fluid at the annulus (between the central tubing and the ID of the chamber) is almost stationary.  Therefore, once the light debris get swept to the corners and fall through the tubing slots, they are more likely settled to the bottom of the debris chamber.  This special debris collector can be attached to the top of a standard WCT debris chamber and help collect light debris to reduce the chance of they blocking the WCT screen.
