摘　　要：通过对光纤陀螺仪、石英挠性加速度计、姿态测量短节、供电短节、泥浆脉冲发生器、地面仪器等关键设备的设计与研制,开发出了一套适合海上作业特点和需求的随钻陀螺测斜系统。室内及现场试验结果表明,自行设计的随钻陀螺测斜系统在大排量钻井环境下能够正常完成井下仪器测斜功能,实时连续提供井筒轨迹数据,测量精度满足异常磁环境下井筒防碰绕障作业要求,地面系统能够完成正常解码,井下仪器结构抗振、耐高温,对钻井环境的适应性强。A gyroscopic inclination survey while drilling system suitable for offshore operation characteristics and needs was developed,including fiber gyroscope,quartz flexible accelerometer,attitude measuring crossover,power sub,mud pulse generator,and surface instruments.Lab and field test results show that the home-made inclination survey system can smoothly measure inclination and azimuth under the condition of high mud flow-rate,and provide real-time and continuous hole trajectory data.The data accuracy meets the need of anti-collision and barrier-bypassing in abnormal magnetic environment,and the data can be decoded normally with surface facility.The downhole instrumentation is vibration-and heat-resistant,and is highly adaptable to various drilling environments.
