Study of the Lithology-Electric Property Relation in "Three-low Reservoir

The study shows that the lithology-electric property relation in "three-low reservoir"(low porosity,permeability and formation water mineralization)is a cubic nonliner function. This paper suggests that pore structure is the main factor of determining the relation,and mineralization has clcar influencc too. Then gives the explanation of influence and relational expression between lithology and formation water resistivity.
