准噶尔盆地玛6井区侏罗系三工河组S_2~2砂层地震相分析
|
摘要
现代新技术手段是克服地震资料解释多解性的重要方法。作者在本文中以三维地震资料为基础 ,运用 Stratimagic地震相分析以及振幅切片等技术手段 ,对准噶尔盆地玛 6井区侏罗系三工河组 S22 砂体展布进行了全面分析 ,识别出研究目的层段骨架砂体的平面展布特征 ,并进一步结合地震剖面的反射结构特征 ,展开精细的地震相研究。研究结果发现 ,玛 6井区三工河组S22 砂层主要为一个三角洲沉积
The new modern techniques are the important approaches of overcoming the multiple interpretations of seismic information. Based on three dimensional seismic data, the paper applies Stratimagic seismic analyses and horizon amplitude and other techniques, making an overall analysis about the distribution of Jurassic Sangonghe Formation S 2 2 sands in Ma6 area in Junggar Basin and identifying the planar distributional characteristics of the skeleton sands in researching target layers. Further more, by combining the seismic profiles' reflection construction features, seismic facies are analyzed in detail. The research results show that Sangonghe Formation S 2 2 sand in Ma6 area is mainly a delta sediment.
