摘　　要：水平井生产测井与常规直井生产测井有较大的差异。对于水平井而言,首先测井仪器需要特殊的输送工艺;其次测量井段更长,产出剖面更多;同时,流体在水平段流动时,由于油气水呈层状分离流动,并受井眼轨迹和各层产出的影响,存在复杂的流态变化,需要采用专门的阵列测井仪器和特殊的解释计算模型。介绍了目前主流的水平井生产测井阵列成像仪器的测量原理,以及水平井生产测井的输送工艺和在川渝地区的实际应用情况。实测资料表明,生产测井阵列成像仪在水平井中具有较好的应用效果,为油田的开采提供了可靠的依据。There are great differences between horizontal well production logging and conventional vertical well production logging. For the horizontal well,firstly the logging tools need special transportation technology. Secondly,the logging interval is longer,and the number of production layer increases. Meanwhile,because of oil-gas-liquid stratified flow,when the fluid flow in the horizontal segment,which is affected by the well trajectory and different reservoirs＇ productions,and the flow patterns become complicated,so the special array logging tools and particular interpretation models are needed to solve those problems. The measuring principle of present mainstream array image tools of the horizontal well production logging and the horizontal well production logging transportation technology are introduced with its practical application situations in Chuan- yu area. Practical logging data indicates that the tools have been applied well in horizontal wells,which can provide reliable foundations for exploitation of oilfields.
