随钻识别水层是录井的重要工作,现有手段识别非常困难。通过分析区域地层水特征,将离子色谱技术应用于录井现场分析,获取各种离子类型与数量信息,采用离子数值法、离子比值法与离子权重交会法,建立随钻录井水层识别方法。上井应用后与测井解释吻合率高,弥补了常规录井手段的不足。 Identifying the water layer with drilling is an important work of logging and the identification of existing means is very difficult. By analyzing the characteristics of formation water in the region, the ion chromatography technique is applied to the on-site analysis of the well logging to obtain information of various ion types and quantities. The ion numerical method, the ion ratio method and the ion weight intersection method are used to establish the logging well identification method . After the application of the well and well log interpretation match rate high, to make up for the lack of conventional logging tools.
