在调研大量文献的基础上,对断层的封堵机制进行了总结分析,并针对5种常用的断层封堵能力评价方法,从各种方法的原理出发,综合分析其优缺点及适用范围。通过比较分析认为:每种评价方法都有其局限性,需要根据该地区具体地质情况综合运用多种方法。开展断层封堵能力定量评价研究的前提是首先要实现上下两盘岩性对接,断层涂抹因子法是目前最为成熟也是应用最广泛的断层封堵性能定量评价方法。
On the basis of a large amount of literature, the fault sealing mechanism is summarized and analyzed. According to the five commonly used methods of fault sealing capability assessment, the advantages and disadvantages of the methods and the applicable scope are analyzed based on the principle of each method. Through comparative analysis, it is considered that each evaluation method has its limitations and needs to use a variety of methods according to the specific geological conditions in the area. The premise of carrying out the quantitative assessment of fault sealing capability is to firstly realize the docking of upper and lower lithology, and the fault smear factor method is the most mature and most widely used quantitative assessment method for fault sealing performance.
