摘要/Abstract

摘要： 断层封闭具有时空的非均质性,断层封闭史应在恢复埋藏史、构造演化史、构造应力场演化史的基础上,利用泥岩涂抹系数和断面应力等方法,定量研究断层不同时期的侧向和垂向封闭性,并结合其他影响因素进行综合评价;断层封油性和封气性之间存在明显的差异,相应的评价标准也不同;模糊综合评判方法克服了以往一些评价方法考虑影响因素不全面的缺陷,所得出的结论更加可信;不确定性分析是对任何断层封闭性研究方法的可信度进行评价的必要环节。

关键词: 断层封闭性, 非均质性, 模糊综合评判, 不确定性

Abstract: Fault sealing is characterized by heterogeneities both in time and space. Based on the analysis of the deposition, tectonic and stress field evolution, using shale smears and section stress methods, a quantitative research on lateral or vertical sealing of fault in different stages is conducted, and a comprehensive evaluation of them is made integrated with other influenced factors. The evaluation standards are different because of the difference between the fault seal oil ability and the fault seal gas ability. Study indicates that the evaluation of fault sealing with synthetic fuzzy judgment is more believable than some methods with incomplete consideration of influenced factors. Besides, the analysis of fault sealing with uncertainty method is indispensable to evaluate the confidence levels of all methods for fault sealing study.

Key words: fault sealing, heterogeneity, synthetic fuzzy judgment, uncertainty
