摘要： An apparatus for use in a wellbore includes a tool string and a plurality of sensors, which include at least a first sensor to detect pressure signals in an inner conduit of the tool string and at least a second sensor to detect pressure signals in an annulus outside the tool string. A controller actuates a tool in the tool string in response to a logical combination of outputs from the sensors, where the outputs of the sensors are responsive to the respective pressure signals.

摘要： A remote actuation tool equipped with an intermediate volumetric mechanism for enhanced tool durability in high pressure differential downhole environments. Valve segments of the tool are actuated by power available due to a pressure differential between atmospheric and hydrostatic chambers of the tool. Yet, the intermediate volumetric mechanism, whether in the form of a discrete chamber or a hydraulic line system, minimizes stresses of the differential pressure on tool hydraulics. Thus, failure rates are substantially reduced. So, for example, the tool may be reliably employed in downhole environments which present differential pressures in excess of about 30,000 PSI.
摘要翻译：配有中间体积机构的远程致动工具，用于在高压差压井下环境中提高刀具耐用性。由于工具的大气压力和静液压室之间的压差，工具的阀段由可用功率驱动。然而，中间体积机构，无论是以离散腔室或液压管路系统的形式，都能最大限度地减少工具液压系统上的压力差。因此，故障率显着降低。因此，例如，该工具可以可靠地用于存在超过约30,000PSI的压差的井下环境中。

摘要： A tool activating system includes a multiple control units coupled to activate devices in a tool string positioned in a well. A processor is capable of communicating with the control units to send commands to the control units as well as to retrieve information (such as unique identifiers and status) of the control units. Selective activation of the control units may be performed based on the retrieved information. Further, defective control units or devices may be bypassed or skipped over.

摘要： A downhole communication system and method is presented for communicating between a downhole location within a wellbore and a surface location. The system preferably comprises a first and second telemetry module, a downhole tool, and an interface electrically connecting the downhole tool to the first and second telemetry modules. The first telemetry module is connected to a string and positioned downhole within the wellbore, and configured to receive communication signals via acoustic propagation or low frequency electromagnetic transmission. The second telemetry module is connected to the string and positioned downhole within the wellbore, and configured to receive communication signals via fluid pressure pulse commands. The downhole tool is operatively connected to the string. And the interface is adapted to selectively relay digital communication signals between the downhole tool and at least one of the first and second telemetry modules.
