摘要(Abstract)：

为了研究储层在注入黏稳剂时电阻率与含水饱和度的关系及黏稳剂对自然电位、核磁响应的影响,开展了岩石物理实验研究。结果表明:在注入含黏稳剂的高矿化度水之后,地层电阻率随着含水饱和度的增加呈下降趋势,矿化度越高,电阻率下降越快;随着注人黏稳剂矿化度的增大,自然电位逐渐增大;注入水矿化度的变化及黏稳剂对T_2谱的影响不大。
In order to study the relations between the resistivity and water saturation and moreover the influences of the injected clay stabilizer on the spontaneous potential and nuclear magnetic response in a reservoir,the researches of the petrophysical experiment are conducted.The findings demonstrate that after injecting the clay stabilizer with high salinity,the formation resistivity is declined with the water saturation increase,the higher the salinity is,the faster the resistivity reduced will be;with the rise of the salinity of the injected clay stabilizer,the spontaneous potential increases gradually;the changes of the injected water salinity and furthermore the clay stabilizer have little effects on T_2 spectral distribution.
