摘要

mechanism for selectively activating a plurality of wells, mechanism for selectively activating a plurality of bottom devices, method for selectively activating a firing mechanism in a plurality of well valves. a mechanism for selectively activating a plurality of wells, including a) a valve having: i) a coupled sleeve for movement between an open and normally closed section; and ii) a sleeve magnet valve assembly; and (b) a well pumping needle including a needle magnet assembly coupled with the valve magnet assembly such that the needle is coupled to the valve when in close proximity e.g. In turn, the sleeve moves from the closed position to the open position.
