This paper introduces something about the electrical logging stresses and the magnetic logging residual stresses of 100,000m 3 oil tank with floating cover imported from other country.Making a comparision analysis between the electrical logging stresses and the theory calculation results shows the aspect of being worthy to be drawed lessen and improve on our design.At the same time,the paper probes the feasibility of determining the residual stresses of the tank wall of oil tank with floating cover by the means of the magnetic logging,and the qualitative analysis is carried out for the result of magnetic logging residual stresses.
