套管井测井新技术进展

随着石油勘探开发的需要, 套管测井技术发展十分迅速。套管井测井可在任何时间获得测井数据, 确定产层产油或产水情况、确定油层的含油饱和度,也可以用于老井评价寻找剩余油、监测油田生产动态变化情况、评价水泥胶结情况、监测油井套损、评价油井使用寿命等。文中不仅介绍了国外套管测井新技术的测量原理, 对于我国当前的科研和生产具有指导和借鉴作用, 而且探讨了我国套管测井技术的现状及差距, 为测井新技术指明了发展方向。

Development of new logging technology in cased hole

For the requirement of petroleum exploration, logging technologies develop rapidly. Almost all logging methods for obtaining log data can be applied in cased hole in any time to determine the production status and the oil saturation in oil layer, to carry out old well evaluation and production performance monitoring, and to evaluate cementation and well service life. The measuring principle of foreign new logging technologies is introduced, which is helpful for guiding our research and production. The current status and gap of logging technologies in China are discussed and the developing direction is pointed out.
