Abstract

The present invention discloses a method for transmitting data using a MWD (Multi-Wave Detection) (MWD) instrument. The method comprises the following steps: designing and developing universal communication code for the MWD probe master control module software and compiling a universal IP address for the downhole instrument to be connected; designing and manufacturing a bus transceiver module and a communication control processing module for a communication interface circuit; selecting the universal IP address as the IP address for the downhole instrument to be connected, establishing communication between the downhole instrument and the interface circuit, and between the interface circuit and the MWD probe; connecting the downhole instrument to the MWD system via the communication interface circuit and the MWD bus, configuring the instrument parameters according to the universal IP address before use downhole, and then connecting the downhole instrument to be connected together with the MWD probe for use downhole. This application avoids modifying the MWD underlying software, eliminating the need to obtain the MWD underlying technology and source code during downhole MWD system development, effectively improving system development efficiency and minimizing the R&D and use costs of downhole instruments.
