摘　　要：多臂井径测井仪用来测量套管的腐蚀、变形,针对仪器在使用过程中出现的问题,对仪器的传感器密封结构、驱动采集电路和地面软件进行了改进与完善,现场应用效果说明改进后的仪器更加稳定,能在175℃、60 MPa的环境下可靠工作,证明多臂井径测井仪能为地质部门提供可靠详实的数据。The multi-arm caliper imaging logging tool is used to measure the casing corrosion, deformation. With view to the problems ari-sing during using, the seal structure of sensor, the drive acquisition circuit and the ground software are improved. The field application shows that the improved tool works more steadily and even under conditions of 175℃ A60 MPa, which proves that the multi-arm caliper ima-ging logging tool can provide reliable and accurate data.
