carbonate cave reservoirs%dual laterolog%finite element method (FEM)%numerical simulation
Cave carbonate formations are characterized by heterogeneity, which makes electrical log prediction difficult.It is currently important to know how to use the dual laterolog to accurately identify and quantitatively evaluate caves.Using numerical simulation to calculate electrical log responses can provide a theoretical basis for cave identification and evaluation.In this paper, based on the dual laterolog principles, we first study different size spherical cave models using the finite element method (FEM), determine a relation between resistivity and cave filling after comprehensively studying the log responses of cave models with different filling material, and finally study the dual laterolog responses on caves filled with shale, limestone, conglomerate, and thin laminated formation of sand and shale.The numerical results provide a theoretical basis for identification and evaluation of carbonate cave reservoirs.
