| Abstract: | Large number of experimental data indicate that reservoir low resistivity is mainly resulted from additional conductivity and cation exchange. The effect of temperature and pressure on each parameter in Archie equation is disscussed , variation rules of porosity index m and saturation index n under high temperature and high pressure are obtained. |
