摘要
推靠系统是井径测井仪实现井筒直径大小测量的主要组成部分,其运动、动力特性与测井数据的准确性紧密相关。为了进一步提高推靠系统的传动性能,结合封闭矢量多边形投影法和矩阵法,对推靠系统打开、测量两种运动状态进行了运动特性分析。在对六臂井径测井仪推靠系统运动学分析的基础上,运用动态静力学方法,对推靠系统两种运动进行了动力特性分析。基于Adams软件进行实例仿真,得出了推靠系统各构件的位移、速度和加速度随时间变化的规律曲线,以及各构件的受力情况,辅助分析和验证了其系统的运动规律,为进行六臂井径测井仪推靠系统的优化设计提供了理论依据。
The push-back system is the main component of the well diameter measuring instrument to achieve the diameter measurement of the wellbore, the motion and dynamic characteristics are closely related to the accuracy of the logging data. In order to further improve the transmission performance of the push-back system,the closed vector polygon projection method and the matrix method are used to analyze the motion characteristics of the push-back system to open and measure the two motion states. Based on the kinematics analysis of the six-arm caliper logging tool push-back system,the dynamic statics method is used to analyze the dynamic characteristics of the two movements of the push-back system. Based on the example simulation of Adams software,the regularity curves of the displacement,velocity and acceleration of the components of the push-back system are changed with time,and the force of each component is analyzed. The motion law of the system is analyzed and verified. The theoretical design of the optimal design of the arm caliper logging tool push-back system provides a theoretical reference.
