Abstract: Daqing Oilfield and other mainland oilfields have stepped into high water-cut stage. The former well logging technique based on the continuous oil phase is not suitable for high water-cut conditions. Impedance productive profile well logging tool measures water-cut in conductive theory with array ringshaped conductive sensors, and conductive sensors have good water-cut resolution in the continuous water phase. Therefore the impedance productive profile well logging tool is suitable for measuring water-cut in high water-cut conditions. By for now the technique has been used in 17220 wells. It has been used for logging of more than 86% wells in Daqing Oilfield, and become the main technique for productive profile well logging in high water-cut oilfields. Now it has been widely used in Daqing Oilfield and Jilin Oilfield.

Key words: impedance, productive profile well logging tool

摘要： 油田步入高含水开发期,地下水为连续相的条件下,原有的基于油为连续相的测井技术不再适用,测井质量难以保证。阻抗式产液剖面测井仪采用阵列环状电极传感器,通过电导法确定含水率,可以在水为连续相时进行过流测量含水率。该技术适合中、高含水条件下油井含水率的测量。截至目前,该技术测井技术已在大庆、吉林等油田已经大规模应用,累计测井17220井次。在大庆油田,应用这种产液剖面测井方法已占测井总数的86%以上,成为高含水油田产液剖面测井的主导技术。
