摘　　要：介绍了井斜的危害,研制了一种新的井斜动态测量试验台,分析了底部钻具的强烈振动和随机转动对井斜测量的影响,转动引起的离心力会使加速度传感器测试信号失真,则用两个加速度传感器对离心力的影响进行修正,为井斜精确测量奠定基础。This article introduced a number of disadvantages caused by well inclination, analyzed the effect to the well inclination with the strong vibration and random rotation of the drilling tools. A new kind of test bench was made which was used to measure the well inclination on-time. The centrifugal force caused by rotation made the signal of the accelerometer sensors distort. So two accelerometer sensors were used to modify the the impact of the centrifugal force. This method layed the foundation for accurate measurement of deviation.
