陆相页岩油气是中国源岩油气最具发展潜力的资源类型，干酪根特性和各向异性是决定页岩油气生产潜能和开发设计的两个重要方面。深入研究干酪根的动态响应特征和各向异性与其影响因素的定量相关性，对增强陆相页岩甜点的地震响应识别以及全面理解各向异性诱发机制具有重要的作用。本项目拟以陆相天然有机页岩的特征为约束，采用基于热压法的可控人工有机页岩建模技术，联合超声测试技术及微观检测技术，建立干酪根含量与不同方向动态参数响应的定量变化规律，明确相关性的微观诱导机制，遴选陆相页岩富有机质层段的敏感参数。同时引入统计数学领域的正交设计法，结合可控人工有机页岩建模技术，解耦各影响因素与各向异性参数间的定量影响关系，揭示各向异性特征的主控因素及其影响规律。通过本项目研究得到的定量变化关系及其机制，对有机页岩的烃类检测及水力压裂天然裂缝改造进而提高采收率具有重要的科学价值。

Terrestrial shale oil & gas is the most potential component type of source rock oil & gas in China. Kerogen and anisotropy - two of the most important factors to determine the oil & gas production potential and their development scheme in shale. The quantitative effects of kerogen content on the anisotropic dynamic parameters as well as varied induced factors on the anisotropy remain to further investigate. In-depth understanding of the relationship will have great significance for enhancing the identification of “sweet-pot” from the seismic profile and the induced mechanism of anisotropy. In this proposal, Hot-pressing based artificial organic-rich shale physical modeling technique, which is restrained by the characteristics of terrestrial natural organic shale, is proposed to construct well-controlled artificial organic-rich shale with different kerogen content. Under this basis, combing with ultrasonic testing technology and microscopic detection technology, quantitative relationship between kerogen content and dynamic parameter can be established. It will help clarify the relevant micro-induction mechanism and select sensitive parameters of organic-rich intervals in terrestrial shale. Meanwhile, the orthogonal design method is combined with the controllable artificial physical modeling technology to decouple the quantitative influence relationships between various influencing factors and anisotropic parameters. Under this basis, the main controlling factors of anisotropic characteristics and their influencing patterns can be revealed. The quantitative relationships and mechanism would have great scientific value for the hydrocarbon detection and reconstruction of natural fracture in hydraulic fracturing to ultimately enhance oil recovery.
