中子寿命测井方法在确定套管外地层的剩余油饱和度 (产水率 )具有良好的精度 ,对认识地下油层状态、地层水淹程度、提供油层中剩余油分布及高产水部位、串槽井段提供了强有力的手段 ,为封堵卡水提供可靠的选层资料 ,为合理调整开发措施提供了依据。通过在濮城油田的应用 ,取得了明显的地质效果。 The neutron lifetime logging method has good accuracy in determining the residual oil saturation (water production rate) in the casing outer layer. It is of great significance to recognize the state of the underground oil layer, the degree of flooding in the formation, The slot section provides a powerful means to provide reliable layer selection information for blocking card water, which provides the basis for rational adjustment of development measures. Through the application in Pucheng Oilfield, the obvious geological effect has been achieved.
