摘要
针对水平井、斜井中多相流流态的测量,Sondex公司推出了多相持率测井仪CAT(电容阵列多相持率测井仪Capacitance ArrayTool)。该仪器采用12个微传感器分布在套管内壁,实时连续测量井筒中的流体流动状态。仪器采用微电容传感器探测各个传感器周围流体的电导率,对于油、气、水,电容传感器测量时产生三种不同频率分别表示三相持率,并且可以直观的成像形式来模拟显示井筒中的流动形态。
The capacitance array tool(CAT),having 12 micro-sensor located on its 12 arms,can continuously measure the fluid flow state in the well bore in real-time.The micro-capacitance sensors measure the fluid conductivity around the sensors to give three frequency signals for the three holdup of oil,gas and water.The tool can provide visual image for the state of flow in the well bore.
