Logging Optimization Processing Method with User-defined Response Equation
摘要
Abstract
At present, response equations involved in the logging optimization processing method are predefined fixed forms.Because of its limited types, the adaptability and calculation precision to the complex reservoir processing are affected.To solve this problem, this paper presents a logging optimization processing method with external user-defined response equation based on the expression analysis technology.Through element analysis of user-input equation, the corresponding automatic computer calculation algorithm of expression derivation and evaluation is established.To solve the nonlinear objective function, the improved algorithm of the penalty function combined with Levenberg-Marquardt is proposed.Application results show that the new method can help to improve the applicability of logging data processing and the accuracy of interpretation results.关键词
