| 摘 要： | 为了建立稳定可靠的利用油页岩总有机碳预测含油率的模型，揭示中国陆相不同成因类型油页岩含油率与总有机碳的内在关系极其重要。通过不同类型盆地油页岩钻井取心测试的关键参数，结合沉积学、有机地球化学、热模拟等学科技术，探讨油页岩含油率与总有机碳的响应机理。结果表明：不同盆地类型与沉积背景下发育的油页岩含油率与总有机碳质量分数均呈现良好的正相关性（R2=0.81~0.97）；中国陆相油页岩的成因类型进一步划分为5种类型，制约着含油率与总有机碳的内在关系；油页岩的升温加热模拟呈现3个失重阶段（温度<150、300~550、600~750℃），明确了含油率与总有机碳参数的物理意义；相同类型盆地与沉积背景下形成的油页岩具有相近的母质生源组合，从而具有大致相当的再生烃效率。中国陆相油页岩成因类型的细划、含油率与总有机碳物理意义的明确、油页岩再生烃能力的分析，有助于理解中国陆相油页岩含油率与总有机碳的内在响应关系。

| Abstract: | In order to establish the reliable model between oil yield and total organic carbon (TOC) of oil shale to predict oil yield, it is very important to reveal the response mechanism between oil yield and TOC in different genetic types of oil shale of continental basins. In this paper, the response mechanism between oil yield and TOC in non-marine oil shale was studied by using the key parameters of borehole cores in various types of basins combined with sedimentology, organic geochemistry, and thermal simulation. The results show that an excellent correlation (R2=0.81-0.97) between oil yield and TOC exists in oil shales from different types of basins and sedimentary backgrounds. Firstly, the non-marine oil shale is divided into five genetic types, which control the relationship between oil yield and TOC. Secondly, three weight-loss stages of oil shales were presented during heating simulation, which clarifies the specific physical significance of oil yield and TOC parameters. Finally, the oil shale formed in similar basin and sedimentary background has similar organic matter source, so it has roughly equivalent hydrocarbon regeneration efficiency. The genetic types of non-marine oil shale, the physical significance of oil yield and TOC parameters, and the hydrocarbon regeneration capacity of oil shale were used to understand the internal relationship between oil yield and TOC of non-marine oil shale in China. |
