摘要： 目前的勘探趋势已由构造油气藏转到岩性复合型油气藏。地层岩性油气藏的勘探难点之一就是如何准确识别小断层和地层油气藏中的剥蚀线。常规相干技术对于断距小于半个同相轴小断层就不尽人意。进行了针对小断层的识别研究,并结合当前最新技术思路,开发出一套基于波形分析技术的识别方法。该方法能够准确识别地层剥蚀线、小断层,提高了解释精度和速度,缩短了解释周期。

Abstract: The present petroleum exploration has trended from structural reservoirs to lithologic and stratigraphic reservoirs. One of the latter exploration focuses on exactly identifying mini-faults and nip-out line in stratigraphic reservoirs. Conventional coherent wave analysis can hardly be used for identifying the mini-faults with fault throw less than half of event. This paper studies such mini-fault identification, and develops a wave analysis-based identifying approach with up to date technologies, by which the stratigraphic nip-out line and the mini-faults can be precisely identified, thus, the interpretation accuracy and velocity as well as analytical cycle could be all improved.

Key words: wave analysis, ni-out line, lithologic reservoir, fault
