METHODS OF CALIBRATING A FLUID ANALYZER FOR USE IN A WELLBORE

摘要

METHODS OF CALIBRATING A FLUID ANALYSER FOR USE IN A WELLBORE (202) ARE DESCRIBED. AN EXAMPLE METHOD OF GENERATING CALIBRATION DATA FOR A FLUID ANALYSER FOR USE IN A DOWNHOLE TOOL INVOLVES LOWERING A DOWNHOLE TOOL INCLUDING A FLUID ANALYSER TO A LOCATION IN A WELLBORE (202), MEASURING, VIA THE FLUID ANALYSER, A CHARACTERISTIC VALUE OF A CALIBRATION FLUID OR A VACUUM WHILE THE FLUID ANALYSER IS AT THE LOCATION, OBTAINING AN EXPECTED CHARACTERISTIC VALUE FOR THE CALIBRATION FLUID OR THE VACUUM AT THE LOCATION, AND COMPARING THE MEASURED CHARACTERISTIC VALUE TO THE EXPECTED CHARACTERISTIC VALUE TO GENERATE A CALIBRATION VALUE FOR THE FLUID.
