Abstract: According to the acquisition and transmitting conditions while drilling, the idea of detecting the signals by means of multi-sensors was proposed to get more accurate data, the reliability of sensors and the relation matrix between multi-sensors were also researched based on the fuzzy theory. The optimal methods of data fusion based on synthesis were presented to process both the example and real data. The processing results imply that the method has exhibited the abilities to reduce uncertainty and noises encountered in singlcsensors detection, which ensures its application in the measure while drilling system in oil field.
