断层在油气运移成藏过程中起双重作用,断层开启为油气运移提供通道,断层封闭为油气藏形成提供遮挡,因此评价断层封闭性对油气勘探开发意义重大。目前研究断层封闭性方法很多,归纳统计可分为岩性角度、力学角度、流体性质、流体包裹体与综合评价五大类。该文选取这五大类断层封闭性研究方法和部分专家的研究实例,详细阐述各类方法的原理、特点以及应用情况,系统总结断层封闭性研究方法,有助于正确评价断层封闭性。

Faults play a dual role in hydrocarbon migration and accumulation,which provides migration paths or close hydrocarbon,so that the evaluation of fault sealing has a great significance in oil and gas exploration and development.There are many ways to study fault sealing at present,and they can be summarized as lithology,mechanics,fluid nature,fluid inclusions and comprehensive evaluation.These different research methods and some study cases from experts are selected to elaborate the principles,characteristics and application of various types of research methods in detail,in order to evaluate fault sealing reasonably.
