摘　　要：对Φ70补偿密度测井仪的推靠结构进行改进 ,采用单、双推靠结构 ,既保持了小井眼仪器的性能 ,又满足了大井眼井测井要求 ,提高了仪器的利用率和价值。The backup configuration of Φ70 compensated density logging tool is improved. Single and double backup configuration are adopted,and this not only maintains tool performance for slim borehole,but also satisfies logging requirement in large borehole,and enhances tool utilization rate and its worthiness.
