Abstract
The present disclosure provides techniques for a self-extendable hydraulic wellbore cleaning tool. The cleaning tool includes one or more extending nozzles which eject cleaning fluid onto the walls of a wellbore with increased impact momentum due to the shorter range. The extending nozzles can extend from the cleaning tool to a distance away from the cleaning tool, bringing the point of ejection closed to the walls of the wellbore. In certain example embodiments, the cleaning tool also includes one or more flow guides which direct the flow of cleaning fluid ejected from the nozzles. The flow guides cause the cleaning fluid to rotate when ejected from the nozzles, and causes the cleaning fluid to impact the walls of the wellbore at an angle.
