Abstract: The drilling engineering parameterwas designedwhile drilling data acquisition system based on DSP technology. It can measure drilling engineering parameter, such as drilling pressure, torque, side pressure and annular pressure etc. The data acquisition system adopted TMS320LF2407A chip ofTI asmain controller, in addition, designed peripheral signal processing circuit, memory module, communication module and so on. A measuring example explains itwas feasible that this data acquisition system was applied to measuring well drilling engineering parameter.

Key words: drilling engineering parameter, measuring while drilling, DSP technology
