摘要： A downhole mixing tool and method for removing sand and other debris from a wellbore which combines the sand with a treatment fluid so that the sand is lifted to the surface of the well for removal. The tool includes a chamber into which the sand laden fluid is drawn and the treatment fluid is introduced. Ports into the chamber are arranged to provide a pressure drop to draw the sand laden fluid into the chamber and a mixing time within the chamber before sand laden fluid of lower viscosity exits the chamber to travel to the surface. Additional features include blades on the tool for breaking up obstructions prior to being drawn into the chamber and a lubricating line through the tool to introduce lubricating fluid to the blades.
