北黄海盆地东部坳陷火成岩地震相识别与分布预测
|
摘要
北黄海盆地东部坳陷火成岩分布复杂并具有多期性,直接影响了油气成藏作用,然而目前对其空间分布尚缺乏深入认识,制约着该区勘探开发的部署。利用全三维地震资料,根据地震反射特征识别出了不同类型的火成岩地震相模式,并对其不同特征进行了分析,通过地震相识别进行平面追踪,结合时间切片三维地震技术及属性分析对火成岩分布进行了预测。结果表明,北黄海盆地东部坳陷主要发育柱状、尖峰状、蘑菇状和丘状4种火成岩反射地震相;研究区火成岩分区性较明显,主要发育3处火成岩体,分别位于东部隆起剥蚀区、坳陷中部和坳陷的西北部。
Igneous rocks,as a kind of reservoir,play significant roles in the accumulation of hydrocarbons.Multistage igneous rocks occur widely in the Eastern Depression of the North Yellow Sea Basin.However,the distribution pattern of the igneous rocks remains unclear so far.In this paper,3Dseismic data is used to identify the types of igneous facies and distribution patterns according to their reflection characteristics.In order to trace the spatial distribution of the igneous rocks,both the technology of three dimensional seismic time slice and the technique of seismic attributes are adopted for this region.As the result,four seismic facies,i.e.the column-like,peak-like,mushroom-like and mound-like igneous bodies,are identified and three igneous complexes found in the eastern erosional area,the center of depression and the northwest part of the depression respectively.
