Actuation system and method for a downhole tool |
摘要 |
<p>An actuation system and method for a downhole tool. The downhole tool includes a body having an axial bore extending at least partially therethrough and a chamber disposed radially-outward from the bore. A valve is disposed within the bore and adapted to move between a first position which prevents fluid flow from the bore to the chamber through a port and a second position which permits the fluid flow from the bore to the chamber through the port. A motor, disposed within the bore, is adapted to move the valve between the first and second positions. An actuatable component of the downhole tool, e.g., a cutter block of an underreamer downhole tool, is movably coupled to the body and adapted to move from a non-actuated state to an actuated state in response to fluid flow through the port into the chamber.</p> |
