摘要
文章介绍了一种采用阵列探针传感器测量持水率的新型产出剖面测井仪,阐述了仪器的测量原理、传感器分布和信号处理等关键技术。由于采用阵列探针传感器及多路信号传输技术,仪器能够直观地反应井下油水分布状况及同步监测含水和流量。实验及现场应用证明该仪器在大庆油田高含水测试中具有广阔的应用前景。
This paper introduces a new production profile logging instrument using array probe sensor for measuring watercut,and elaborates its measuring principle,sensor distribution and signal processing technology.The array probe sensor for measuring watercut and multi-channel signal transmission technology can more intuitively reflect oil-water distribution of downhole and monitor watercut and flow synchronously. Experiments and field application show this logging instrument has broad application prospect for high water cut measurement in Daqing oilfield.
