裂缝性储层AVO检测方法综述

Review of AVO detection methods for fractured reservoirs

涉及裂缝检测方法研究的内容很广泛,从裂缝的弹性理论到裂缝的定量解释,国内外都有研究。从国内外各向异性的研究现状出发,总结了目前裂缝性储层检测的主要方法,重点阐述了纵波AVO检测裂缝性储层的理论基础和实用方法。纵波的AVO属性,尤其是方位AVO属性、井孔或VSP和井间地震的转换波属性,对检测裂缝发育程度具有较好的敏感性。

Wide-ranging materials are available relating the study of fracture detection both at home and abroad, which is from the elasticity theory to quantitative interpretation of fracture. Based on a review of research status of anisotropy, this paper introduceds several methods that are widely used in fracture detection, especially the fundamentals and methodologies of P-wave AVO technology. P-wave AVO, especially azimuthal AVO, converted-wave AVO of borehole, VSP, and crosswell seismic are sensitive to fractures.
