摘要
通过泥岩沾污潜力、泥岩沾污因子及断层泥比率表征公式及应用条件的对比分析,指出了泥岩涂抹的4种成因及其公式的局限性;总结了岩性配置的各种研究方法及应用条件,阐述了岩性配置研究中断层面和断裂带对封闭性的影响,认为岩性配置分析面临的一个最大挑战就是确定断层的规模、断层岩的总厚度及小断层的分布等;提出断层封闭机理的3个方面及相关的8种类型;把断层封闭性研究方法归纳为14种,并加以讨论;最后从断层封闭机理、断层封闭性研究思路、计算机应用等方面对断层封闭性的进一步研究方向进行了展望。
According to the corelation analysis of characterization formulas and applied conditions of clay smear potential, shale smear factor and fault clay ratio, four kinds of origins and limitations of shale smear formulas are pointed out. Various methods and applied conditions of lithology allocation are reviewed. The effects of fault plane and faulted zone on fault seal property are given in the study of lithology allocation. It is suggested that the big challenge for analysis of lithology allocation is to determine the fault scale, total thickness of fault rock and distribution of small faults, etc. The fault seal mechanism can be divided into three aspects or 8 types. And the methods for study of fault seal property are classified into fourteen types and discussed. Finally, further research directions or targets in fault seal are provided from the aspects of fault seal mechanism, studied thinking as well as the application of computer.
