泰国中部Wichian Buri组火山岩裂缝预测

摘要

在火山岩油气藏勘探上，一直以裂缝性思想为指导，将火山岩油气藏类比裂缝油气藏进行研究。油气藏储层裂缝形态呈多样性，裂缝的形成受多种因素控制，其物理属性复杂，表现出很强的各向异性。在砂岩、泥质岩和碳酸岩甚至火成岩中均可能存在裂缝性储集层。裂缝多为后期生成，不象其它油气藏具有相应的沉积环境特征。所以裂缝性油气藏比常规油气藏更难于勘探。本文着重强调叠后地震资料的预测流程和解释方案，利用叠后地震资料来预测泰国中部Wichian Buri组火山岩储层裂缝，并取得了良好的检测效果。%Volcanic rock reservoir exploration has always been guided by the fractured thoughts. Fractures morphology of reservoir showed diversity. The formation of the fracture were controlled by many factors and showed strong anisotropy. In sandstone, argillaceous sandstone and carbonate rock even in igneous rock reservoir are possible to find fractured reservoir. Facture were always paulopost, unlike other reservoir has the characteristics of the corresponding sedimentary environment. Fractured reservoirs are more dififcult to explore than conventional reservoirs. In this paper, the authors emphasis on the forecast flow and explain plan of post-stack seismic data, using post-stack seismic data to predict fractured reservoir, and achieved good test results.
