摘　　要：为实现基于地震信息的松辽盆地古龙页岩油甜点空间刻画,开展典型岩心样品声学测试及岩石物理分析、模型正演分析,研究岩石物性参数与弹性参数之间关系以及甜点的地球物理响应特征,并利用定量叠前反演技术对甜点特征进行预测解释。研究表明:有机碳含量、页理等甜点潜在控制参数可引起弹性参数及地震响应特征较明显变化;基于实验室岩石物理测试及甜点物理规律分析,结合高精度的叠前弹性参数反演,能较好刻画甜点的空间分布。研究成果为古龙页岩油甜点空间分布描述及井位部署提供了重要技术保障。In order to realize the spatial characterization of the sweep spots in Gulong shale oil reservoirs of Songliao Basin based on the seismic information,the acoustic test,petrophysical and model forward analyses of the typical core sample were conducted,the relationships among the rock physical property parameters and the elastic parameters and moreover the geophysical response characteristics of the sweet spots were studied.And furthermore with the help of the quantitative pre-stack seismic inverting technology,the prediction interpretation of the sweep spots characteristics was conducted.The research results show that the potential controlling factors of the sweep spots,such as the organic matter content,lamellation and so on can result in the obvious changes of the elastic parameters and seismic response characteristics.Based on the laboratory petrophysical test and the sweet-spot physical law analysis,and moreover integrated with the high-precision pre-stack elastic parameter inversion,the spatial distribution of the sweep spots can be well characterized.The study achievements can provide the technical support and guarantee for the spatial distribution description of the sweet spots and the arrangement of the well location in Gulong shale oil reservoirs.
