发明名称 Instrumentert sementeringsplugg og system for samme
摘要 <p>A system for cementing a tubular member in a well bore includes a cementing plug. The cementing plug includes at least one sensor. The system transmits a value measured by the sensor to a surface location. The system may transmit the value measured by the sensor through a cable connected between the plug and the surface location. Alternatively, the system may transmit the value measured by the sensor acoustically to the surface location.</p>
