摘要(Abstract)：
从文献分析入手,总结归纳了断层封闭性研究的几个主要方面:封堵模式、封闭性影响因素、封闭性评价方法、存在的问题,在对每一个问题分析的基础上提出了个人看法。封闭性影响因素有很多种,重点论述了断层泥、流体性质及温压系统、岩性配置、断层的组合形式和断层封闭史等;同时对断层的5种封堵模式(岩性配置封堵模式、时间配置封堵模式、主应力封堵模式、泥岩塑性流动封堵模式及排替压差封堵模式)进行了论述;简单介绍了两大类研究方法所包括的主要内容;最后指出了存在的问题。
Based on literature analysis, several main research aspects about fault sealing capacity were generalized: plugging modes, influencing factors of sealing capacity, evaluation methods of sealing capacity and existent problems. Private opinions were put forward based on analysis of each question. Many factors can affect sealing capacity, and the factors of fault clay, fluid property, temperature-pressure system, lithology assembly, combinatorial forms of faults, sealing history of fault, and so on, were discussed mainly ; five types of plugging modes of fault, including lithological arrangement plugging mode, time arrangement plugging mode, main stress plugging mode, shale plastic flowing plugging mode and discharging pressure difference plugging mode, were established in this paper; main contents of two kinds of researching methods were introduced briefly; current problems and further research were also discussed.
