摘要 |
A method and equipment for an instrumented tubular joint apparatus for use in a pipe string comprising an upper tubular section with a threaded connection thereabove and an axial passage for fluid to flow through connected to a lower tubular section with a threaded connection therebelow and an axial passage for fluid to flow through, a sensor to measure strain at the instrumented tubular joint, a data recording and transmitting unit operatively connected to the sensor, means to relate the data acquired by the sensor to a surface processing unit; and a mechanism to disconnect the upper section from the lower section after receiving a signal from the surface processing unit. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. |
