摘要： Integrated drilling and evaluation systems and methods for drilling, logging, and testing wells are provided. The drilling and evaluation systems are basically comprised of a drill string (18), a drill bit (30) carried on the power end of the drill string (18) for drilling a well bore, logging while drilling apparatus (28) included in the drill string (18) for identifying subsurface zones or formations of interest, packer means (32) carried on the drill string above the drill bit for sealing a zone or formation of interest below the packer means (32), a fluid testing means (26) included in the drill string (18) for controlling the flow of well fluid from the zone or formation of interest into the drill string (18), a functional status monitor included in the drill string (18) to evaluate the capacity of the various test instruments to function, and a function timer (31) included in the drill string (18) to automatically sequence the steps of the various test procedures. The drilling and evaluation systems and methods for using the systems allow one or more subsurface zones or formations of interest in a well to be drilled, logged, and tested without the necessity of removing the drill string (18) from the well.

摘要： A method of selectively actuating from a remote location multiple downhole well tools includes: selecting one of the well tools for actuation by applying a voltage polarity to a set of conductors in the well, thereby operating a downhole pump connected to the well tool and displacing a piston of the well tool in one direction; and selecting the well tool for actuation by applying an opposite voltage polarity to the set of conductors, thereby operating the downhole pump and displacing the piston in an opposite direction. A system includes multiple electrical conductors in the well; and multiple control devices that control which of the well tools is selected for actuation in response to current flow in a set of the conductors, each of the control devices including at least one downhole pump which applies a pressure differential to an actuator of a respective one of the well tools.

摘要： Well tools including valves operable by low electrical input. One well tool includes a valve (30) which controls fluid communication between pressure regions (32,34) in a well, the valve including a rotatable member (48) which is biased to rotate, and a brake or clutch (46) which prevents rotation of the member. Another valve includes a barrier which separates reactants, with the valve being operable in response to the barrier being opened and the reactants thereby reacting with each other. Yet another valve includes a barrier which separates the pressure regions, and a control circuit which heats the barrier to a weakened state. Another valve includes a member displaceable between open and closed positions, a restraining device which resists displacement of the member, and a control device which degrades or deactivates the restraining device and thereby permits the member to displace between its open and closed positions, in response to receipt of a predetermined signal.
