【摘要】 针对油田开发钻井剖面地层对比的具体特点和实际问题应满足的约束条件,提出了一种基于目标约束遗传算法的地层对比方法。该方法既能较好地完成常规地层对比,也可对因断层或地层尖灭等地质现象造成的地层缺失、错位等复杂情况进行处理。该方法具有较好的鲁棒性,随机搜索能力强,对复杂情况下的地层对比具有较好的适应性。给出了具体的实现算法,对实际资料的处理结果证明了方法的有效性。更多还原

【Abstract】 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.更多还原
