摘要
断层封闭性问题受多种地质因素的影响和控制.以陈堡油田为例,提取多种影响断层封闭性的主控因素,应用改进的模糊综合评判方法对断层的封闭性进行评价,在各因素权重系数的求取过程中应用权的最小平方法,避开了一致性检验.评价结果表明该油田主要断层封闭性评价是可靠的,为下一步勘探开发提供了科学依据.
There are many geological factors of controlling the sealability of faults.Taking Chenbao Oilfield as an example,several main controlling factors are extracted and the sealability of the faults in this oilfield is evaluated using improved fuzzy comprehensive evaluation method.In the process of deciding the weight coefficient of each factor,minimum square method is used and therefore the consistency checking is avoided.The evaluation results show that the sealability of the main faults in the oilfield is reliable,which provides scientific basis for further exploration.
