Epos3.0地震解释系统在准噶尔盆地车排子地区火山岩油气勘探中的应用
|
摘要
火山岩油气藏已经成为准噶尔盆地西北缘油气勘探及开发挖潜的一种重要油气藏类型,而火山岩体的识别是车排子地区石炭系油气勘探的关键。利用该区钻井资料及岩性解释结果,对车排子连片三维地震资料进行精细标定,划分出3个火山岩喷发序列,并应用Epos3.0地震解释系统对划分出的3个序列进行精细解释,再应用高分辨率本征值相干算法落实断裂组合,利用多属性划分的地震相图确定火山岩相的平面分布,通过独特的异常体雕刻技术确定火山岩体的空间分布,最终发现和落实12个火山岩体圈闭,Epos3.0地震解释系统在该地区取得了良好的地质应用效果。
The volcanic reservoir has become one important type of oil-gas exploration and development in the northwestern margin of Junggar Basin.The identification of volcanic massif is the key of Carboniferous oil-gas exploration in Chepaizi area.The drilling data and lithologic interpretation in the study area are applied to carry out the fine calibration of3D seismic data,and three volcanic eruption sequences are identified.Epos 3.0 seismic interpretation system is used to carry out the fine interpretation,high resolution coherence technique is applied to perform the fault assemblage,multi-attribute seismic facies map is applied to ascertain the plane distribution of volcanic phase,and anomalous body carving technology is used to determine the spatial distribution of volcanic massif.12 volcanic massif traps are finallydiscovered.The application ofEpos 3.0 seismic interpretation systemin this area achieves good geologic effects.
