Downhole multiple bore rotary diverter apparatus |
摘要 |
A downhole rotary diverter assembly includes multiple passages for selectively aligning with multiple boreholes. The diverter assembly can be selectively actuated to direct a tool or tubing through-passage toward a desired borehole. The primary tool through-passage of the diverter assembly can be alternately and continually aligned and re-aligned with a desired borehole out of multiple boreholes, while the diverter assembly remains in the well. After a single trip into the well, and placement of the diverter assembly in a well junction, the diverter assembly can be actuated to rotate flow passages into alignment with multiple boreholes. An actuation tool may be lowered into the diverter assembly and manipulated to activate a mandrel. The mandrel is guided by an indexing mechanism to rotatably cycle through discrete and predetermined alignment positions that correspond generally with the stop positions of a guide pin in a guide slot of the indexing mechanism. |
