摘　　要：密闭取心分析的含水饱和度是目前获取储层含水饱和度的有效方法,然而由于密闭率低或不密闭,钻井过程中有一部分水基泥浆滤液浸入了岩心,使得实验室分析的含水饱和度不能真实反映地下情况。本文提出一种方法,可以基本上校正滤液浸入对分析含水饱和度的影响,校正后的含水饱和度数值更能反映地层实际情况。At present Water saturation of sealed coring analysis is valid method for acquiring reservoir water saturation,but because confinement rate is low or leakiness,some water base mud filtrate invades into the core in the well drilling process, the water saturation of lab analysis can＇t redlect the true subsurface conditiono It is proposed that a method is used to correct the effect of mud filtrate invasion to water saturation of analysis,the water saturation value after correction can reflect the the true subsurface condition.
