摘　　要：根据油水两相流在水平井中分层流动的特性,研制出一种用于测量油水分层界面的阵列探针式水平井油水两相流成像仪。依据油水导电率不同的特性,利用24个探针对油水界面进行区分。在多相流模拟水平井中进行了动态模拟实验,实验结果表明:仪器含水率测量分辨率优于10%。现场实际测井,该仪器具有良好的稳定性与准确性,为水平井含水率测量提供了新的手段。According to the characteristics of stratified flow of oil-water two-phase flow in horizontal wells, an array probe oil-water two- phase flow imaging instrument for measuring oil-water stratified interface is developed. Using the different conductivity characteristics of the water and the oil, 24 probes are used to the instrument to distinguish the oil-water interface. The dynamic simulation experimental results in horizontal wells of multiphase flow show that the measuring instrument resolution is better than 10% moisture content. The field applications show this logging instrument has good stability and accuracy, and provides a new method for measuring water content in horizontal wells.
