Select fire system and method of using same

摘要

A bailer bottom, bailer system, and method for performing bailer operations at a wellsite are disclosed. The wellsite is positioned about a wellbore penetrating a subterranean formation. The bailer bottom is deployable in the wellbore. The bailer bottom includes a plurality of downhole components and a select fire unit. The plurality of downhole components includes a cement unit which includes a cement chamber and a valve. The cement chamber has a port therethrough in selective communication with the wellbore via the valve. The select fire unit includes a downhole switch electrically coupled to the plurality of downhole components. The downhole switch has a polarity for each of the plurality of downhole components. The downhole switch is triggerable to selectively move between the multiple polarities to selectively pass a signal to one of the plurality of downhole components whereby the plurality of downhole components are selectively activated.
