摘要

vibration and pressure measuring device in a well integrated in a pipe section as part of a production pipe. The invention relates to a pressure and vibration measuring device integrated in a pipe section (1) as part of a production pipe (20). the sensor housing (2) of the sensor measuring device has a two-part clamp (3) on the top of the sensor housing (2), from which a multi-conductor cable connection (10) of at least four preferably six, nozzles in the tube (9) are secured along the production pipe (20) with bushings through well-mounted equipment to electronic sensors and with a control unit (12) above the wellhead. uniformly radially arranged in an annular space (5) are a first set of strain gauges (7) attached to the outer wall of the production pipe (20) and a second set of strain gauges (8) connected within the outer wall of the sensor housing (2). the voltage gauges (7, 8) are connected by glass passages (4) from electrical conductors in cable hoses (9a) terminated in pipe hooks (21) to an electronic unit (11) and a control unit (12). ). For temperature measurement, a thermometer will be integrated. where pressure measurement signals also measure vibrations in the production pipe (20). (Fig. 1b)
