生产测井资料是稳定流动状态下生产井生产动态的物理响应，它不仅直接反映了生产井的生产状况，而且反映了井内各产层和地层中流体参数及其变化。文中详细介绍了用生产测井资料来确定井点各产层的剩余油饱和度、供液边界压力、渗透率和表皮系数的方法，并用实例来证实了该种方法的可行性，评价结果与实际生产情况基本一致。

Production logging data is the physical respond to well production dynamic under stable flowing, which reflects not only the production status of well directly, but also the fluid parameters and their changes in production layers and other strata in a well. This article, in detail, introduces the methods of determining the remaining oil saturation, the reservoir pressure, the permeability and the skin factor of each pay by using production logging data, and the feasibility of the methods is verified by application examples. The evaluating result is basically consistent with the real production situation.
