基于改进模糊综合评判法的断层封堵性综合评价
Comprehensive Evaluation of Fault Sealing Based on Improved Fuzzy Comprehensive Evaluation Method
,
断层封堵评价分为垂向封堵评价和侧向封堵评价.前人多采取综合模糊评价法综合评价断层封堵性,模糊综合评判法的评价结果受评价分值和权重系数影响,传统综合评判法的各参数评价分值通过最大隶属度原则获取,忽视了同一类评价标准的内部差异,精度较低,且权重系数采取经验赋值或同等权重赋值,与实际区域地质环境有所出入.本次研究综合考虑断层力学背景、岩性对置关系、断储配置关系等定性参数,结合断层岩泥质含量、断面正压力、断储排替压力及断层应力特征等定量参数的影响,实现了参数的评价标准定量化分值表示;且基于区域各项参数统计分析,各项参数权重系数的确定通过层次分析法予以改进,权重系数更符合区域规律.选择涠西南凹陷二号断裂带A块潜力目标作为靶区,运用该方法进行评价,取得了较好效果;与前人研究方法对比,精度存在显著提高.
