【摘要】 火山岩作为一种特殊的储集层逐渐成为油气勘探的重要目标。由于火山岩探区地质条件复杂,且成层性差,岩体发育,厚度变化快,用常规的地震解释手段难以满足火山岩解释的需要,运用层序划分、地震相、三维可视化等技术,在火山岩解释中用火山构造和层序地层有效结合,关注不整合面、喷发间歇面和岩体顶底面,分析古、今构造及火山岩形成演化,落实火山岩体与岩相期次、分布,最终实现火山岩精细地震解释。近几年在三塘湖盆地火山岩勘探中火山岩精细地震解释逐步形成一套技术系列,对火山岩基础研究提供了大力的支持,收到很好的效果。更多还原

【Abstract】 As a special reservoir, volcanic reservoirs gradually become an important target of oil and gas exploration. Because of the complex geological conditions in volcanic rock prospect area, as well as with the characteristics of the difficult stratification, developed rock mass, various thicknesses, it is difficult to meet the needs of the volcanic explanation using conventional seismic interpretation methods. So we use stratigraphic classification, seismic phase and 3-D visualization technology, combine with volcanic structure and stratigraphic sequence, concern unconformity surface, eruption intermittent face and upper surface and base of rock mass to analyze ancient and modern structure and volcanic rock formation and evolution, to determine the volcanic rock body, lithofacies periods and distribution, and finally to achieve the fine seismic interpretation for volcanic rock. In recent years, a set of technical series on volcanic fine seismic interpretation have been formed in the volcanic exploration of Santanghu basin, it strongly supports the volcanic fundamental research and takes a good effect.更多还原
