摘要
鉴于我国页岩油在类型划分、评价方法、评价参数标准和资源潜力预测等方面存在较大分歧的现状,将页岩油划分为夹层页岩油、纯页岩油和原位转化页岩油三大类。根据这三大类页岩油明显不同的赋存与形成特征,分别建立了相应的容积法、基于热解烃S1含量体积法、基于氢指数变化的生烃量法资源量计算方法模型,并确定各种方法模型的关键参数及参数下限标准,最后按照统一的参数标准评价了我国主要盆地页岩层系的三大类页岩油资源量。我国纯页岩油、夹层页岩油、原位转化页岩油地质资源量分别为145.4×10^(8), 95.1×10^(8),708.2×10^(8)t,可采资源量分别为9.4×10^(8),7.1×10^(8),460.3×10^(8)t。评价结果表明,我国页岩油资源丰富,是推动国内原油增产稳产的重要接替领域。
In view of the large differences in type classification,assessment methods,evaluation parameters and resource potential prediction of shale oil in China,shale oil is classified into three categories:interlayer shale oil,pure shale oil and in⁃situ converted shale oil.According to the obviously different occurrence and formation characteristics of the three types of shale oil,the corresponding resource calculation method models,respectively named volume method,volume method based on pyrolysed hydrocarbon S1 content and hydrocarbon generation quantity method based on hydrogen index variation,were put forward,and the key parameters and their lowest threshold standards of each model were determined.Finally,the three categories of shale oil resources in the major basins in China were evaluated according to the unified parameter criterion.The in⁃place resources of pure shale oil,interlayer shale oil and in⁃situ converted shale oil are 145.4×10^(8) t,95.1×10^(8) t and 708.2×10^(8) t,respectively,and the recoverable resources are 9.4×10^(8) t,7.1×10^(8) t and 460.3×10^(8) t,respectively.The evalua⁃tion results show that China is rich in shale oil resources,which is an important replacement field to promote domestic crude oil production increase and stabilization.
