Rotary steerable drilling technology for future drilling development trend has caused people s extensive concern, and underground engineering parameters of the measurement while drilling is Is one of the important components of. To this end, introduced the engineering parameter measuring instrument and the basic principle of star 5 well in experimental situations, obtained in the experiments Large underground near bit drilling pressure and torque data, engineering parameter measuring instrument and site condition very well. From the experimental results, the tool can Enough to meet the actual drilling operation condition, and can clearly be near drill work, the analysis of the actual working condition of the downhole tool is provided for theOften intuitive means
