有机-无机协同成岩作用及其对页岩油成储的影响——以东营凹陷为例

页岩油是未来油气勘探的重要领域，具有源储一体的特点。页岩油储层的形成是集有机质生烃与储集空间形成演化于一体的综合过程，该过程中有机-无机协同成岩作用是页岩油成储的关键，也是当前研究的薄弱环节。东营凹陷页岩油资源潜力大，基础资料丰富，本项目以页岩岩心为基础，利用多维度不同尺度的观察及定量测试手段，首先开展精细的有机与无机组分的赋存方式、储集空间及烃类赋存等页岩微观组构特征的研究；在此基础上结合成岩模拟和生烃模拟，理清页岩有机-无机协同成岩作用机制，以岩石类型为单元，分析细粒物质矿物转化序列、储集空间的形成及有机质演化等规律，建立有机质演化与矿物转化、储集空间及储集性能的匹配关系；分析成岩过程中不同尺度的储集空间的有效性、含油性及油赋存状态；建立有机质演化、成岩作用、储集空间形成与页岩油赋存的匹配机制。以期取得页岩油成岩成储机理创新性成果，并发表3篇以上国际SCI期刊论文。

Shale oil is an important exploration area for hydrocarbon resources, which is an assemblage of source rock and reservoir. The reservoir formation of shale oil is a synthesis process, integrating the hydrocarbon generation and the storage space formation, in which, the organic-inorganic synergistic diagenesis is the key and the current weak study. The Dongying Depression has great shale oil resource potential and abundant geological materials and data. Based on shale cores, using the multi-dimensional observation and quantitative test methods at different scales, firstly carry out sophisticated ways occurrence of organic and inorganic components. Combined with diagenesis simulation and hydrocarbon generation simulation, make clear the organic-inorganic synergistic diagenesis mechanism of shale, analyze the regularity of mineral transformation, storage space formation and organic matter evolution, establish the relationship between organic matter evolution with the mineral conversion, storage space and reservoir properties, study the effectiveness, oil-bearing property and hydrocarbon occurrence of different storage space, and ultimately establish the matching mechanism of organic matter evolution, diagenesis, and reservoir space formation and shale oil occurrence. We expect to obtain innovative achievements on shale oil reservoir formation mechanism, and publish 3 or more SCI papers in key international periodicals.
