摘　　要：红浅1井区目前开发增产压力较大,加密井因临近老井蒸汽吞吐的影响出现不同程度水淹。储层水淹后电性、物性的变化导致测井特征复杂多变,水淹层识别难度大,测井解释符合率较低。本文通过对水淹层特性分析找出油层水淹与测井响应变化之间规律,结合高温相对渗透率实验结果,得出水淹层解释方法,与研究区水淹层实例对照,表明该解释方法准确率较高,可以为稠油老区调整工作提供依据。At present Hongqian well field 1 is difficult to increase the production.The infilling wells are affected by steam stimulation in the nearby old wells resulting in waterflooding in varying degrees.After waterflooding,the variation of electrical and physical properties of the reservoirs makes logging characteristics complex and changeful.It is difficult to identify water-flooded zones and well logging interpretation coincidence rate is low.Through analysing the characteristics of water-flooded zones to find out the law between waterflooded reservoirs and logging response,the interpretation method for water-flooded zones is achieved.Cases of the studied area indicate that the method has high accuracy and can provide a foundation for adjustment of old areas of heavy oil.
