摘要
在利用排替压力差研究断层侧向封闭机理的基础上，根据断层两盘岩层的接触关系，建立了断层侧向封闭模式。利用断移地层的砂泥岩比值、页岩涂抹系数和声波时差，分别研究不同地质条件下的断层侧向封闭性，实际应用表明，这些方法用于研究断层的侧向封闭性不仅行之有效，而且具有很强的针对性。
Based on studying the lateral sealing mechanism of fault by the differene of displacement pressure and the contact relation between two blocks of faults, this paper established the lateral sealing model of fault, studied the lateral sealing of faults in different geological conditions by the ratio of sandstone and mudstone in faulted strata, shale smear coefficient and interval transit time. The application of actural examples indicate that these methods can be used in studying the lateral sealing of fault.
