断层封堵性评价方法及影响因素分析

Analysis and Research on Evaluation Method and Influencing Factors of Fault Sealing

断层不但可以作为油气运移通道,而且还可以对油气起到一定的遮挡作用。在油田勘探开发过程中,通过对断层封堵性进行分析与评价,能够对油气分布进行推断,因此,对断层封堵性的研究具有十分重要的现实意义。基于此,主要对断层封堵性评价方法及影响因素进行了分析与探索,首先简要介绍了断层封堵性,然后系统总结了断层封堵性评价方法,主要包括定性分析与定量分析,然后指出了断层封堵性的影响因素。

Faults can not only serve as oil and gas migration channels, but also play a role in blocking oil and gas. In the process of oilfield exploration and development, the distribution of oil and gas can be inferred through the analysis and evaluation of fault plugging. Therefore, the research on fault plugging has very important practical significance. This paper mainly analyzes and explores the evaluation methods and influencing factors of fault plugging. Firstly, it briefly introduces the fault plugging, and then systematically summarizes the evaluation methods of fault plugging, which are mainly divided into two types:(1) qualitative analysis;(2) Quantitative analysis, and then pointed out the influencing factors of fault sealing.
