摘　　要：旋转导向钻井技术能够成功实现的关键技术之一是要实时测量出近钻头处的钻井工程参数(钻压、扭矩、侧向力等)。研制了一种井下工程参数测量短节,它可连接在钻柱的不同部位随同钻柱下井,实测、记录并存储钻柱在井下不同位置的受力情况,在测量短节中安放井下电源、传感器及数据采集电路,配置了MWD数据接口,可实现数据存储和实时传输,这样就可获取到真实的井下工程参数,还可将数据用于钻柱动力学分析以验证各理论模型的准确性。介绍了测量短节的结构设计、强度校核与加工制造。The Rotary Steerable Drilling System can be realized successfully,the key technology is real-time measurement of downhole drilling engineering parameters（WOB,torque,side force,etc.）.First a measurement sub for downhole engineering parameters is developed,which can connect different parts of the drilling string and run in hole with drilling string.Then the loads of drilling string in different positions is measured,recorded and stored.And underground power supply,sensors and data acquisition circuit are put in place during measuring the sub,equipped with MWD data interface to achieve storage and real-time data transmission.The real downhole engineering parameters are obtained,which could be applied in dynamic analysis of drilling string to verify the accuracy of the theoretical model.It focuses on the mechanical structure design,strength check and manufacturing of measurement sub.
