Methods and systems for estimating formation resistivity and porosity
摘要
A method for analyzing a subterranean formation porosity is disclosed. The apparent dielectric constant of the subterranean formation and an apparent resistivity of the subterranean formation are measured. The measured values are used to determine a measured formation loss tangent. The formation water loss tangent can be expressed by the water dielectric constant and the water resistivity. The measured formation loss tangent and the formation water loss tangent are then used to determine at least one of an actual dielectric constant of the subterranean formation water and an actual resistivity of the subterranean formation water. The actual formation porosity may be obtained using the estimated water resistivity and water dielectric constant.
