针对碎屑岩中正断层侧向封堵性评价的10种研究方法，文中从各方法的基本原理入手，分析其优缺点及适用范围，从而进行了全面的论述和评价。断层侧向封堵性评价方法可概括成4类：Ⅰ类是断层岩封闭法；Ⅱ类是断层两侧流体相关参数对比法；Ⅲ类是岩性对接封闭法；Ⅳ类是综合法。每个断层侧向封堵性评价方法都有一定的局限性，具体选用何种评价方法，要具体情况具体分析确定。总的来说，岩性对接分析和断层两侧流体分析是对地质特征的基本描述，是评价或预测断层侧向封堵性的基础。若是砂砂对接，则SGR法是目前比较成熟的评价方法。

According to ten evaluation methods of the lateral sealing of normal fault in clastic reservoirs, the advantages, disadvantages and application range of each method are discussed comprehensively based on basic principles in this paper. The evaluation methods of lateral sealing of fault are summarized into four categories, they are fault rock sealing, the related parameters analysis of fluid on both sides of faults, lithology juxtaposition and comprehensive method. Each method has certain limitations and is selected according to the specific situation analysis. But in general, lithology juxtaposition and the related parameters analysis of fluid on both sides of faults are the basic descriptions and the basis of sealing evaluation and prediction. If fault juxtaposition is against reservoir rock, SGR is more mature evaluation method at present.
