火山岩地震储层学

随着国内外火山岩油气藏的不断发现,有必要建立火山岩地震储层学来满足勘探开发的迫切需要。火山岩地震储层学是地震储层学的一门分支学科,主要研究盆地构造环境及火山岩储层的岩性和岩相特征、储集空间类型、物性特征、外观形态特征和所含流体特征等在三维空间的变化,实现火山岩的储层建模。地质、地震、测井等多学科协同研究是火山岩地震储层学研究的根本方法。岩矿测试分析技术、测井岩性识别技术、储层地震预测技术、流体预测技术、储层建模技术和三维可视化技术是火山岩地震储层学研究的六大关键技术。火山岩地震储层学适用于油气勘探到开发的各个阶段。由于受现有地震资料分辨率的限制,对火山岩优质薄储层仅能识别到10m左右,对储层物性、储层流体性质等方面的研究还处于半定量化阶段。

Volcanic seismic reservoir

Along with more and more volcanic reservoirs discovered, it is necessary to establish volcanic seismic reservoir to meet the urgent needs of petroleum exploration and development. Volcanic seismic reservoir is a branch science of seismic reservoir, and it mainly researches basin tectonic setting, volcanic lithology and lithofacies characteristics, reservoir space type, physical properties, appearance characteristics and the fluid characteristics in three-dimensional space, so as to carry out volcanic reservoir modeling. Multi-disciplinary collaborative research, such as geology, seismics and logging, is the fundamental method for studying the volcanic seismic reservoir. Rock and mineral analysis, logging lithologic identification, reservoir seismic prediction, fluid prediction, reservoir modeling and 3D visualization are six key technologies of studying volcanic seismic reservoir. Volcanic seismic reservoir can be applied to the various stages from exploration to development. However, due to the limited resolution of the existing seismic data, the recognition range of high-quality thin beds of volcanic rock is only 10 m or so, and the research of the reservoir properties and reservoir fluid properties is still in the semiquantitative stage.
