碳酸盐岩缝洞型储层,由于泥浆的侵入使得用饱和度、视地层水电阻率等参数识别流体性质成为难题.在三孔隙度模型计算孔隙成分的基础上,提出了一种分不同孔隙成分计算混合液电阻率的方法,求得混合液饱和度,并讨论了消除泥浆侵入影响的投影作图法.用塔里木盆地北部奥陶系碳酸盐岩测井资料验证了方法的有效性.

. In carbonate and vug reservoirs, it was difficult to identify fluid property with the parameters of water saturation and apparent formation-water resistivity. A method was presented to calculate mixed fluid resistivity based on the component of porosities calculating by triple model and project mapping for removing mud invasion effects. The method is verified by using well logging data of Ordovician carbonate in northern Tarim Basin.
