摘　　要：为了使测斜传感器在动态情况下能够测量得到准确的井眼姿态参数,文章从测斜传感器单轴石英加速度计的数学模型入手,通过分析其传递函数,提出了旋转条件下测斜传感器离心加速度的消除方法"动态频率补偿法"。并通过实验和实验数据的分析处理,验证了"动态频率补偿法"在旋转导向系统中的可行性。In order to obtain accurate profile parameters of the borehole in the dynamic circumstances. Begin with the mathematical model of single-axis quartz accelerometers installed in the inclinometer, The paper analyses transfer function, and presents a method for eliminating centrifugal acceleration under the inclinometer rotation, that is dynamic frequency compensation law. Experiments and experimental data analysis verify the dynamic frequency compensation law is feasible in rotary steering system.
