页岩油岩石物理及地震响应特征分析

errestrial basins in China contain huge shale oil resources. On the basis of primary data of well-logging and single-well evaluation from the Jiyang depression, logging response characteristics of shale oil have been verified, which are high in GR, neutron density, and resistivity, but low in density. According to the Mineral composition of Shale oil reservoir in studied area, a model of bulk-volume rock is proposed to conduct the analysis of Rock physics simulation of TOC. The relationships between the TOC content of shale oil and rock physical parameters shows that vertical and horizontal wave velocity and density of shale oil are inversely proportional to the TOC content. Combined prestack seismic data with logging data, AVO forward modeling analysis is carried out. As a result, influence of thickness,organic matter content on AVO response characteristics is analyzed.
