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。
Volcanic reservoirs have become an important oil and gas reservoir type for oil and gas exploration and exploitation in the northwestern margin of Junggar Basin. The identification of volcanic rocks is the key to the exploration of Carboniferous hydrocarbon in Chepaizi area. Using the drilling data and interpretation results of lithology in this area, the 3D seismic data of car row contiguous can be finely calibrated, and three volcanic eruption sequences are divided, and the three sequences are interpreted finely by Epos 3.0 seismic interpretation system , And then apply the high-resolution eigenvalue coherence algorithm to implement the fracture combination. Using the multiphase seismic facies map to determine the plane distribution of the volcanic facies, the unique anomaly carving technique was used to determine the spatial distribution of the volcanic rock mass. Finally, 12 Volcanic body trap, Epos3.0 seismic interpretation system in the region has made good geological applications.
