Application of casing resistivity logging technology in a certain oilfield
The casing resistivity logging technology has a wide range of applications in determining potential oil reservoirs,reservoir monitoring,evaluating the degree of reservoir flooding,quantitative calculation of residual oil saturation,formation permeability evaluation,and supplementing openhole well logging data.This time,the technical principles and influencing factors of casing resistivity were analyzed,and an oilfield was selected as a case to carry out the application of casing resistivity logging in four aspects:residual oil saturation evaluation,qualitative evaluation of leakage oil and gas reservoirs,evaluation of water flooding degree and dynamic monitoring of water injection,and the results showed that casing resistivity logging technology has reliability in oilfield development.
