The logging evaluation methods and techniques on domestic and foreign carbonate reservoir were researched from the four aspects of reservoir type classification, parameter characterization, fluid property discrimination and mathematical method. The physical parameters of fracture cave reservoir were calculated using the data of conventional logging and new logging technologies (electrical logging and sonic logging), and on this basis, the fluid property can be discriminated by the conventional logging, nuclear magnetic resonance and dipole shear sonic logging. By comparison with the results of core analysis, this method for calculating reservoir parameters is not only effective, but also simple and feasible. The mathematical method and the new logging technique data are very important for the complex carbonate reservoir evaluation, and can solve the calculation and evaluation problems of complex carbonate reservoir.
