Abstract:

Based on the Biot model, we performed the inversion of reservoir parameters with improved niche ant colony algorithms (INACA). In order to overcome the premature problem of inverse process, the improved niche ant colony algorithms are constructed by combining the fitness-sharing principle which is one of the niche methods with the ant colony algorithm. The numerical results indicate that the relative error of single parameter inversion can be maintained at less than 0.4 percent; particulary, the relative error of porosity is less than 0.02 percent. However, the inversion effect of two-parameter inversion was found to be slightly weak, but the relative error can still be maintained at less than 7.5 percent. Moreover, the antinoise property of the method was also verified. The results of numerical simulation demonstrate that the method is an effective convergent optimization method.
