Abstract: The authors of the paper designe a data acquisition system of drilling engineering parameter while drilling based on strain measuring technology. By means of four strain gauge fullbridge mode, drilling engineering parameters, such as drilling pressure, torque, side pressure and annular pressure etc. can be measured while drilling. The data acquisition system adoptes ADμC8xx series single chip as main controller, in addition, peripheral signal processing circuit, memory module, communication module and power supply module and so on are designed, too. The experimental result suggests it is feasible that this data acquisition system is applied to measure well drilling engineering parameters.

Key words: stain measuring technology, drilling, drilling engineering parameter, measuring while drilling, data acquisition
