    摘要： A system for the measurement and surface data acquisition for optical fiber sensors containing Bragg gratings for the sensing of physical parameters originated from a set of oil wells, the system including: an optical system for signal processing, the signals being originated from physical parameters sensors installed in one single or in a set of oil and/or gas wells and resulting from the reflected wavelength in response to a perturbation of the physical parameter under measurement; an electronic system for signal processing for converting the optical intensity signals originated from the optical system into electrical signals with the aid of detectors that optimize the signal/noise ratio; and an optical switcher having an interface between a) and b), for expanding the number of monitored oil wells.

    摘要： This invention comprises a system for measurement of temperature and pressure in oil wells. It comprises a single hybrid mandrel housing a double pressure and temperature optical sensor, capable of measuring temperature and pressure both in the ring and in the production tubing of an oil well and an insertable venturi tube inserted in the direction of a pressure differential optical sensor, capable of taking flow rate measurements, the installation aspects of which are substantially simplified.With the proposed construction, it is possible for one single hybrid mandrel (30) to read the pressure and temperature in the ring and tubing and the flow rate. With this, changes of flow rate are also possible, without the need to stop production for long periods for the hybrid mandrel (30) to be replaced, the mere replacement of the insertable venturi (12) sufficing, by means of an insertion and extraction GS tool (17), which is an operation requiring a much shorter time.
