高矿化度地层水地区水淹层识别的几种实用方法

Several Practical Methods of Identifing Watered-out Zones in High Salinity Regions

水淹层解释受注入水性质、水淹程度、泣采井网等动态因素的影响而具有相当的难度。以大量已投产证实的生产实际资料为基础,分析归纳出利用电阻率、自然电位、压力系数等信息来识别水淹层的方法,具有资料丰富、方法实用且直观等优点,适应于高矿化度地层水地区的水淹层解释。

The watered-out zones, interpretation are very difficult because they are affected by many dynamic-factors, such as the quality of injection water, the degree of watered-out and patterns. Based on the proven production data,the article analyses and concludes the methods used to distinguish watered-out zones by means of resistivity, spontaneous potential, pressure coefficient and so on . Having many advantages, it is suitable for water-out zones,interpretation in high salinity regions.
