Abstract：On the basis of electrical experiment of rocks in different salinity,performing the study for relative volume of bound water in shaly sand under different salinity and its electrical properties is to reveal the change of electrical properties in shaly sand caused by variation of bound water saturation and formation water salinity.The study showed that the shaly sand in different salinity of saturated fluid has different bound water saturation,and decreasing the bound water saturation with increasing the salinity of saturated fluid.The resistivitx of rock under the condition of bound water is under the influence of resistivity of formation water,bound water saturation and shaly additional conductivity.In a condition of lower formation water salinity,the resistivity of rock may appear low resistivity property because of higher bound water content and shaly additional conductivity.
