摘　　要：介绍井径测井仪的工作原理、信号处理和数据传输方法 ;传感器、陀螺仪的工作原理 ;成像技术的应用 ;井径曲线的对比。通过对井径测井技术的分析 ,整理出了由于电子技术和计算机技术的发展所呈现出的井径测井技术井径臂数量不断增加、电子集成化不断提高、传感器使用精度的不断进步、获取所需数据的不断完善和精确等历史发展过程 ,肯定了多臂井径测井技术的应用前景。Introduced are the measuring principle, signal processing and data transmission of the caliper logging tools; the operating principle of the sensors and gyroscopes; application of imaging technology; and comparison of the caliper logging curves. With the developments of electronics and computer technologies, the number of arms in calipers has been increased which has improved the data reliability, signal processing highly intergrated, the sensors further sophiscated, and more complete log data successfully obtained, showing the bright future of the multi-armed caliper logging technology.
