Abstract Seismic characterization for continental shale oil key sweet spot factors is very difficult due to its fast varying.
Based on rock physics testing, an anisotropy rock physical model is built and some effective parameters are selected using fo r
seismic prediction. Combined with rock physical analysis, well log evaluation and seismic imaging, high resolution and
accuracy seismic inversion methods are applied for predicting clay content, laminated structure, thin layer, fracture, brittl eness
and stress. A series of seismic prediction algorithms are implemented and applied to some typical areas for sweet spot factor
characterization and evaluation. The effect is good and the methods are valuated.
Key words continental shale oil; key sweet spot factors; rock physics; seismic characterization
引言
我国陆相页岩油甜点要素主要包括页岩油层的含油性（TOC、RO、S1、S1/TOC、含油饱和
度）、储集性（岩相、孔隙空间类型、孔隙结构、孔隙度）、可动性（裂缝及层理发育、孔隙压力、
渗透率、流体性质、气油比）、可压性（脆性、裂缝、地应力、埋深、构造背景、可压指数等）等。
近年来在济阳坳陷、东濮凹陷、苏北盆地、南襄盆地、江汉盆地、鄂尔多斯盆地、四川盆地、准噶尔
