The logging identification, validity evaluation and fluid identification of carbonate solution-vuggy reservoirs are very difficult. One important reason is that the response characteristics of dual lateral resistivity logging are complex. The aim of this research is to investigate the relationship between the reserving space characteristics of different reservoirs and the resistivity response of dual lateral logging in carbonate solution-vuggy reservoirs. Based on the constant flow principle and the finite element numerical simulation technology, the instrument and formation models for dual lateral logging resistivity simuation were constructed. The resistivity of dual lateral logging of dissolved pore reservoir, spherical cave reservoir and elliptical spherical cave reservoir with different sizes were simulated. The result show that continuous dual lateral logging simulation is feasible by using the finite element method. The electrical balance of the supervisory electrodes can be obtained by using the global ordinary differential equations (ODE). The system coefficient of deep lateral electrode (Kd) is 0.693m and the system coefficient of shallow lateral electrode (Ks) is 1.222m. The resistivity of dual lateral logging in dissolved pore reservoir, spherical cave reservoir and elliptical spherical cave reservoir decreases greatly on the basis of the resistivity of bedrock. Due to the influence of the reservoir type and the size of cave, the decrease degree of resistivity, the shape of resistivity curves, and the diffence characteristics between deep and shallow lateral logging are very different.
