摘　　要：海上油田水平井含水上升问题突出,水平井找水能够提高开发效果,但水平井找水从基础理论到测井仪器和解释评价方法与常规直、斜井不同。通过研究适用于水平井生产测井的FSI流体扫描成像测井资料处理方法,结合常规的均值法和面积法,提出了利用积分法计算井筒的持率、速度和流量,实现更精确的水平井三相流产出剖面解释。实例应用表明,解释精度满足实际生产的需求。As water cut riseis prominent in offshore horizontal wells,water detectioncan improve the development effect.However,from basic theory to logging tools,the methods of water detection and interpretation&evaluation in horizontal wells are different from those in conventional straight and inclined wells.By studying the FSI method suitable for horizontal wells,combined with the conventional mean and area methods,an integral method is proposed to calculate the wellbore holdup,velocity and flow volume,so as to achieve more accurate interpretation of three-phase flow profile.The application shows that the interpretation accuracy can meet the demand of practical production.
