中文摘要：

针对电容阵列测井仪（CAT）水平井油水两相流测井资料,已有的基于高斯权重的改进多相流动成像算法的成像效果严重依赖于数据的来源,对来自某仪器的数据展示出了好的效果,而另外某仪器的数据成像效果很差。分析了已有算法的不足,指出设计成像算法时需要考虑12个探头的响应不一致性,充分考虑流型的特点。给出了水平管及近水平管油水两相流动试验的结论：当总流量不大于300m3/d时,流型是相间界面光滑层流和界面波动层流。对水平井油水两相流动,提出了仅对界面附近区域进行局部插值的成像算法。实测数据的处理结果表明了该算法的有效性、稳定性。

英文摘要：

It is useful to generate images from logging data of oil-water two-phase flow in horizontal wells obtained by capacitance array tool（CAT）.But the quality of the images come from the existing modified multiphase flow imaging algorithm is closely related to the source of logging data.It is good for data comes from a certain instrument,at the same time,it is bad for data comes from the other one.Firstly,the paper analyzes the shortage of the existing algorithm,the inconsistency of the twelve sensors obtained in CAT and the flow pattern characteristic.The author thinks it should consider these factors when designing imaging algorithm.Then,it introduces the results of oil-water flow experiments in horizontal and nearly horizontal tube.That is,the flow pattern is static flow with smooth interface or wavy interface when the total flow rate is less than 300m3/d.For oil-water two-phase flow in horizontal wells,the paper proposed a new imaging algorithm which is interpolate only in region neighboring interphase interface.The result generated from the practical data indicates that the new algorithm is efficient and stable.
