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。
Volcanic rock, as a special reservoir, has gradually become an important target of oil and gas exploration. Because of the complex geological conditions, poor stratigraphy, rapid development of rock mass and rapid change of thickness, it is difficult to meet the needs of volcanic interpretation by conventional seismic interpretation methods. By means of sequence stratigraphy, seismic facies and 3D visualization, In volcanic structure and sequence stratigraphy effective combination, focusing on the unconformity surface, eruption intermittent surface and top and bottom of rock mass, ancient and modern structure and volcanic rock formation and evolution, implementation of volcanic rock and lithofacies period, distribution, and ultimately achieve the fine volcanic rocks Earthquake explanation. In recent years, volcanic rocks in the Santanghu Basin volcanic rock exploration fine seismic interpretation and gradually form a set of technical series, volcanic basic research provided strong support, received very good results.
