摘要
介绍了AVO技术的基本理论,并对Aki&Richards近似公式三项式、二项式与精确公式计算结果进行了比较。从AVO的属性解释、AVO属性交汇分析及AVO/AVA约束稀疏脉冲同时反演技术等方面,开展了页岩气储层含气性预测,取得了较好的应用效果。
This paper introduced the basic theory of AVO technology, and compared the results of the trinomial, binomial of AkiRichards approximation formula and the exact formulas. From the aspects of AVO attribute interpretation, AVO attribute intersection analysis and AVO/AVA constrained sparse pulse simultaneous inversion technology, this paper carried out gas bearing prediction of shale gas reservoirs which achieved good application results.
