Reaming tool

Abstract

A reaming tool including a channel body having a fluid channel disposed therethrough. The channel body includes a rotational coupling structure that allows the channel body to rotatably couple. The channel body includes a jacket, a dynamic sleeve, a static sleeve, and a static mandrel. The reaming tool includes a rotational discharge body fixedly coupled to the channel body and including a fluid conduit system. The fluid conduit system is shaped to impart rotational force on the rotational discharge body when fluid is forced therethrough. The rotational discharge body includes a post enclosed by stacked discharge plates. The fluid conduit system includes an array of curved conduits. The reaming tool includes a reamer housing fixedly coupled about the rotational discharge body.
