DYNAMIC SCALE REMOVAL TOOL

摘要

A scale removal tool with adjustably positionable fluid dispensing arms. The scale removal tool may be configured for delivery to within a hydrocarbon well via coiled tubing. Thus, fluid may be driven through the coiled tubing and through the tool at the fluid dispensing arms. The fluid may thereby be jetted at high pressure toward scale at the wall of the well in order to achieve its removal. In the case of a well having scale of varying thicknesses, the fluid dispensing arms may be dynamically positioned and repositioned while downhole in the well, depending on scale thickness. In this manner, the tool need not be removed from the well in order to reposition the fluid dispensing arms for optimum scale removal at each section of the well. As such, considerable time and expense of a scale removal application may be saved.
