致密油作为一种非常规油气资源,具有低孔隙度、低渗透率、强非均匀性等特点,常规地震处理技术在致密油预测上面临较大挑战.本文系统地回顾了致密油储集区的有机质富集区、含油性、孔隙度、脆性以及裂缝五个方面的地震评价思路;并详细讨论了地震反演技术在致密油储层上的适用性;最后对地震技术在致密油预测上的应用做了初步展望,建议在今后的工作中可着重研究适合致密油储层特点的地震岩石物理模型,以及兼顾精度和效率的地震反演方法. As a kind of unconventional oil and gas resources, tight oil has the characteristics of low porosity, low permeability and strong nonuniformity, and the conventional seismic processing technology faces great challenges in the prediction of tight oil.This paper systematically reviews the tight oil reservoir And the seismological evaluation of five aspects of organic matter enrichment zone, oil content, porosity, brittleness and fracture; and discussed the applicability of seismic inversion technology in tight oil reservoirs in detail; Finally, the seismic technology in the prediction of tight oil It is suggested that in the future work, the seismic petrophysical model suitable for the characteristics of tight oil reservoirs should be emphatically studied, and the seismic inversion method taking both precision and efficiency into account.
