APPARATUS FOR REMOVAL OF MILLING DEBRIS |
摘要 |
An apparatus and method for drawing small milling debris into a combination milling and debris retrieval tool, during the performance of the milling operation. A milling tool has a fluid intake port near its lower end, where debris-laden fluid is drawn into the milling tool and subsequently into a separator section. The separator section has a debris deflection tube and a screen for separating the debris from the fluid. Fluid is drawn into the tool by either a set of eductor nozzles or a downhole motor and pump.
