摘　　要：通过建立二维重力加速度计在旋转状态下的数学模型,在指出了离心力和切向惯性力是影响井斜动态测量的主要因素的基础上,提出了利用低通滤波器滤除转动导致的附加信号的井斜动态测量方法。利用ADAMS仿真验证了该理论的正确性,并通过不同情况下的实验数据进行比较分析,证明了井斜动态检测方法是可行的。Different dynamic measurement methods for hole inclination were introduced based on accelerometer. Through establishment of mathematical model about two-dimensional gravity acceleration gauge while rotating, the major factors which effect the hole inclination dynamic measurement, centrifugal force and tangential inertial force were pointed out. A new inclination dynamic measurement method was proposed, in which a low-pass fiher was used to remove the additional signal caused by rotation. Then the theoretical was verified with the ADMAS simulation. Compared and analyzed the experimental data under different circumstances, the feasibility of the method was verified.
