摘要
In order to model the actual situation about the borehole-to-surface potential excited by complex pipe network linear current source in oil field,this paper proposes a borehole-to-surface potential 3D FEM modeling method with complex pipe network linear current source and continuous variation of conductivity of the semi-underground space.The results can privide references for identifying the distribution of residual oil and the frontier of water injection,at the same time,a good foundation for 3D inversion of the borehole-to-surface potential.
