WELL TOOL FOR MOUNTING IN WELL AND METHOD FOR ACTIVATION OF WELL TOOL FOR USAGE IN WELL SHAFT Russian patent published in 2006 - IPC E21B43/1185 E21B47/12 

FIELD: building and operation of wells, possible use for activation of well tools, in particular, during perforation, during mounting of packers.

SUBSTANCE: well tool contains multiple control blocks, each one of which has microprocessor and initiator, connected to microprocessor; each microprocessor is made with possible realization of two-sided connection to controller via communication line and with possible receipt from controller for activation of appropriate control blocks of a set of appropriate activation commands, each one of which contains a unique identifier, matching a certain control block. Each control block contains a common flexible board, on support surface of which appropriate microprocessor and initiator are mounted. After placing well tool into well shaft, connection between controller and well tool via communication line is set up. Well tool may contain well tool adapters, each one of which contains appropriate control block and explosive substance, which is detonated by appropriate initiator, and one detachable adapter, connected to adapters, and containing same components except explosive substance. Sensors may be connected to microprocessors. Communication line may be a fiber-optic one.

EFFECT: increased safety of well tool activation.
