摘要
在单芯电缆测量的脉冲中子氧活化仪器中,如何从地面实现对井下中子管的控制是一个非常复杂的问题。通过C8051F040单片机对中子管的灯丝电压、靶压以及阳极脉冲进行控制,使其工作在一个理想状态,是提高仪器测井效率、延长中子管使用寿命的重要手段。
How to control the downhole tool′s neutron tube from the surface is a complex problem in the pulse neutron oxygen activation logging tool,which measures through a single core cable.By using C8051F040 SCM to control the neutron tube′s filament voltage,the target voltage and the pulse of the anode,the downhole tool can work at an ideal state.Thus the downhole tool′s logging efficiency is improved and the working life of the neutron tube is prolonged.
