摘　　要：目前油田相当一部分产液井产液量相对较低,井下含水率高。这些特点给油井找水工作增加了很大难度,必然要求测试仪器具有适用于高含水率、低产液量的特点。取样式环空找水组合测井仪与常规过流式仪器相比,有着独特的优势,测量含水时不受井筒内流体的流速和抽油机冲程波动的影响。仪器含水测量精度可达到±5%以内,极大地提高了含水参数资料录取的准确性,对油田动态监测具有重要意义。At present,a comparative partial of liquid wells have the characters of low yield and high water cut,which enhance the difficulty of finding water in oil wells.The sampling annulus water detector has particular advantages over the conventional through the flow tool.Its water cut measurement is not influenced by the velocity of flow in oil wells and the undulation of pumping unit stroke.Its water cut measuring accuracy is less than ±5%.It greatly improves the veracity of the water cut parameter data.
