Abstract

The invention relates to a multi-bus data fusion processing method and system based on a logging instrument, and belongs to the technical field of oil and gas drilling measurement data transmission. The method comprises the following steps: receiving logging data acquired by a measuring probe of a logging instrument and different data packets sent by a system bus; carrying out primary processing, self-identification, self-diagnosis and self-correction on the received logging data; identifying and converting the received different data packets; performing real-time fusion processing on the logging data after self-identification, self-diagnosis and self-correction and the data packet after identification and conversion; and according to different communication protocols, packaging the data after real-time fusion processing, and sending the packaged data to a system bus and / or a storage unit. According to the invention, a multi-bus data fusion processing system is formed, and the fusion processing system is embedded into the logging instrument passing through the drilling tool, so that data interaction between the logging instrument and other instruments in an instrument string is realized, and parallel processing and self-diagnosis functions of multiple groups of data can be realized.
