说明：  旋转导向钻井技术作为未来钻井的发展趋势已引起人们的广泛关注，而井下工程参数的随钻测量则 是其中的重要组成部分。为此，介绍了工程参数测量仪的基本工作原理和在文星5 井的实验情况，实验中取得了 大量的井下近钻头处的钻压与扭矩数据，工程参数测量仪与现场工况非常吻合。从现场实验结果来看，该工具能 够满足实际钻井的工况条件，并且可以清晰地得到近钻头工作情况，这为分析井下钻具的实际工作情况提供了非 常直观的手段
(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)
