Field Applications of Conductivity Correlated Flow Rate Logging Tool

HU Jin-hai,LIU Xing-bin,ZHOU Jia-qiang,ZHANG Yu-hui,HUANG Chun-hui (Logging & Testing Services Co. of Daqing Oilfield Co.LTD., Daqing, Heilongjiang 163153, China)  
Conductivity correlated flow rate logging tool is mainly for measuring watercuts and flow rates of oil/water two-phase fluids. The tool uses one same conductive sensor to measure the watercuts and flow rates, i.e., to obtain the watercuts from the ratio between conductivity of oil/water miscible fluids and that of the water-phase fluids flowing through the sensor; and to figure out the flow rates from correlation calculations of transit time of flow noise signals travelling through the upper and lower sensors. Introduced are the sensors structure, specifications and operating principles, as well as the surface data acquisition processing hardware and software of the flow measuring part in this tool. Given are the results of indoor dynamic experiments and field log applications. This tool has a wide range of flow measurements and is able to measure watercuts in the flowing state,but its sensor works only under the condition of continuous water-phase. Therefore, the tool′s watercut measuring range is limited within 50% to 100%. This tool has become a useful tool without movable parts but with one same sensor measuring the flow rates and watercuts.
