BRUSH TOOL FOR CLEANING DOWNHOLE TUBULAR BORE

摘要

An elongate brush tool for cleaning a bore of a tubular comprising a first end, a second end, a body between the ends, a plurality of necked channels in an radially exterior portion of the body, each necked channel having a proximal end with an opening, a distal end having a stop, a slot between the proximal end and the distal end, and a channel closure member removable securable to the body, and further comprising a plurality of brush elements, each having a head and a plurality of bristles forming a bundle extending from the head, the brush element head being sized for being received through an opening, of a necked channel and into the necked channel with the bundles received within the slot. A plurality of channel closure members prevent removal of the head of the brush elements from the necked channel during use of the brush tool.

主权项

1. A brush tool, comprising:
an elongate body having a center axis, a first end, a second end, and a plurality of radially outwardly necked channels fanned in a radially exterior portion of the body, each necked channel having an opening at a proximal end and a stop at a distal end, each necked channel having a slot extending from the opening to the stop, and each necked channel extending circumferentially from the proximal end and about the center axis of the body to the distal end; a plurality of brush elements, each brush element having an enlarged head that is larger than the slot of each necked channel and sized to be laterally received through the opening of a necked channel into the necked channel, and a plurality of bristles, each bristle having a proximal end secured to the head and a distal end extending outwardly from the head, the plurality of bristles of each brush element being positioned relative to the head for being laterally received into the slot of a necked channel as the head of the brush element is being laterally received into the opening of the necked channel; and a plurality of channel closure members, each channel closure member securable to the body proximal to the opening of a necked channel to block the heads of a plurality of brush elements from being removed from the necked channel; wherein each of the plurality of brush elements is securable within one of the plurality of necked channels of the body by receiving the head of the brush elements through an opening of a necked channel and into the necked channel and by receiving the plurality of bristles of the brush element into the slot of the necked channel, and by securing a channel closure member to the body proximal to the opening.
