A Method of Stratigraphic Correlation Based on Target Constraint Genetic Algorithm
一种基于目标约束遗传算法的地层对比方法*

Aim at the concrete characters of well log stratigraphic correlation in oil field development and the constraint conditions that the practical problems should satisfy,a stratigraphic correlation method based on target constraint genetic algorithm is proposed.This method can perform the routine stratigraphic correlation better,and also can treat many complicate circumstances such as the formation lacuna,formation malposition and so son.These circumstances may be caused by geologic phenomena including slide or formation pinch out and so on.This method has a better robustness and its random search ability is strong,and it has a better adaptability to stratigraphic correlation under complicate circumstances.The concrete realization algorithm is given in this paper,and the effectiveness of this method is proved by the result of practical data processing.
