Abstract
This disclosure provides a downhole debris removal apparatus, a method for operating a downhole debris removal apparatus, and a well system including the same. The downhole debris removal apparatus, in one aspect, includes an inner pipe positioned within a tubular, and a filtration member substantially encircling the inner pipe. The downhole debris removal apparatus, in this aspect, further includes a cleaning assembly positioned radially about at least a portion of the filtration member, the cleaning assembly configured to move relative to the filtration member to dislodge particulate matter from the filtration member.
Claims21
A downhole debris removal apparatus, comprising:
- an inner pipe positioned within a tubular;
- a filtration member substantially encircling the inner pipe;
- a cleaning assembly positioned radially about at least a portion of the filtration member, the cleaning assembly configured to move relative to the filtration member to dislodge particulate matter from the filtration member;
- and
- a bypass assembly coupled to the inner pipe, the bypass assembly configured to open when a pressure differential between an exterior of the inner pipe and an interior of the inner pipe hits a predetermined value, wherein the bypass assembly is configured to prevent a packoff situation in the downhole debris removal apparatus.
