Interchangeable measurement housings

摘要

Apparatus and methods for operating the apparatus provide a modular unit of hardware to make measurements in a well. The modular unit may include a housing arranged for placement in a drill-string element, where the housing includes a sensor and is structured such that the housing is transferable to another drill-string element without a calibration during or after the transfer. The drill-string elements associated with the transfer may be of different sizes.

1. A system comprising:
a sensor housing containing a detector, the sensor housing arranged for placement with a drill-string element, the sensor housing being a modular unit of hardware to make measurements in a well; and a processor operable to apply calibration coefficients from a data storage unit relative to a measurement reading from the detector such that the sensor housing is transferable to another drill-string element without a calibration measurement during or after the transfer, the calibration coefficients including calibration data correlated to variations in spacing and/or orientation associated with the detector due to the transfer to another drill-string element.
