Bohrlochsignalübertragung und Erfassung durch Metallrohre
摘要
<p>Systems and methods for downhole communication and measurement utilizing an improved metallic tubular (30) having an elongated body with tubular walls and a central bore (32) adapted to receive a run-in tool (10). The tubular including slotted stations to provide through-tubular signal transmission and/or reception. Hydraulic isolation between the interior and exterior of the tubular is provided by pressure barrier means at the slotted stations. Sensors and/or sources are mounted on the run-in tool, which is adapted for transmission through a drill string to engage within the tubular in alignment with the slotted stations. A run-in tool configuration includes a modulator for real-time wireless communication with the surface and/or remote downhole tools. A tubular and run-in tool configuration also includes inductive couplers (122) for wireless signal data transfer. A method for measuring a formation characteristic utilizing a run-in tool adapted with an interchangeable end segment for multi-mode downhole transport. Methods for sealing an opening (38) on the surface of a tubular having an elongated body with tubular walls and a central bore. <IMAGE></p>
