摘要
泥质砂岩电阻率、视地层因素、视胶结指数、电阻率增大系数、视饱和度指数均与温度有关。岩石电阻率随温度的升高而减小 ;泥质砂岩的视地层因素、视胶结指数 ma随温度的升高而增大 ;泥质砂岩的视电阻率增大系数 Ia、饱和度指数na随温度的升高而减小 ;泥质砂岩视地层因素与地层水电阻率有关 ,随地层水矿化度升高而增大。
Resistivity apparent formation factor, apparent cement exponent, resistivity index and apparent saturation exponent of shaly sands are related to temperature. The rock resistivity decreases with the increase of temperature. The apparent formation factor and the apparent cement index m a increase with the increase of temperature. The apparent resistivity index I a and the apparent saturation exponent n a decrease with the increase of temperature. The apparent formation factor increases with the increase of the salinity of formation water.
