Characteristics and effect factors of seismic velocity in metamorphic rock area:An example from CCSD borehole area;
变质岩区地震波速度的特点及其影响因素——以中国大陆科学钻探孔区为例
Based on overlaying velocity data, mudstone thickness was predicted by using the rules of seismic wave velocity changes of itself and inherent relations between lithological properties, mudstone porosity was transformed by using interval velocity, thus vitrinite reflectance of source rocks was further predicted, therefore mature hydrocarbon source rock area was determined, and bases were p.
根据叠加速度谱资料,利用地震波速度参数自身的变化规律与地下岩性之间的内在联系,预测了泥岩厚度;利用层速度,进行泥岩孔隙度转换,从而进一步预测烃源岩镜质体反射率,最终定量地圈定凹陷主力烃源岩的成熟区,为区带评价优选提供了依据。
Because of large variation range on the seismic wave velocity and complex structure in Ciyutuo Oilfield,it s necessary to research the seismic wave velocity so as to offer accurate tectonic basis for geometric arrangement of wells.
在地震地质解释过程中,地震波速度是地震解释资料中重要的参数。
Through the study of horizontal slice,slice along layer and vertical slice,it focused on the variation rules of seismic wave velocity vertically and horizontally in Jiangling Depression,and also analyzed the cause of horizontal change of seismic w.
地震波速度是地球物理勘探和开发中最重要的一个参数。
