The Prediction Method of Diffracted Wave Attribute on Buried Hill Fractured Reservoir

摘要: 潜山裂缝型油气藏的勘探重点之一是裂缝发育区域的预测,本文发展了应用绕射波属性数据进行裂缝分布描述的方法,并提出利用主成分分析方法,结合绕射信息及敏感属性提取,给出裂缝预测的工作流程。模型试算表明绕射波场能够较好地反映构造裂缝的分布规律。将该方法应用于裂缝型油藏精细描述中,绕射波分析方法能够更为精细、全面地描述潜山裂缝型油气藏中裂缝的分布规律。

Abstract: The prediction of fracture-developed area is one of the most important missions for exploration of reservoir of fractured buried hill. A fracture predicted flow based on diffracted wave attribute is proposed, and the principal component analysis algorithm is used to extract diffraction information from seismic field. Meanwhile, via forward modeling, it is the practicability that the flow prove and it's indicate that diffraction attributes can descript the fracture distribution effectively. Finally, the fracture predicted flow is proved feasibility and accuracy to descript the character of fractured reservoir in practice.
