摘要/Abstract

摘要： 针对中国陆相页岩非均质性强的特点，指出夹层页岩油资源评价适宜采用小面元容积法，纯页岩油资源评价适宜采用小面元体积法。建立S₁与TOC拟合关系曲线和轻烃恢复系数与R_o关系曲线，求取原始S₁。确定纯页岩油资源评价的4个关键参数（S₁、TOC、c和页岩厚度）、夹层页岩油资源评价的3个关键参数（夹层累计厚度、孔隙度和含油饱和度），相应地制定参数下限标准。在统一评价方法和标准下，分别选取松辽盆地北部白垩系青山口组页岩油、鄂尔多斯盆地三叠系延长组页岩油和准噶尔盆地二叠系芦草沟组页岩油作为典型评价实例。评价结果揭示，青山口组一段（青一段）纯页岩油资源量为52.23×10⁸t，其中，轻质油（R_o>1.2%）为11.18×10⁸t；延长组长7₃亚段页岩油资源量为66.80×10⁸t，其中，夹层页岩油资源量为27.73×10⁸t，纯页岩油资源量为39.07×10⁸t；芦草沟组页岩油资源量为15.62×10⁸t，其中，夹层页岩油资源量为11.99×10⁸t，纯页岩油资源量为3.63×10⁸t。

Abstract: Given the strong heterogeneity of continental shales in China, small element volumetric method should be adopted for resource assessment of interlayer shale oil and small element volume method for pure shale oil. The fitting relationship curve between S₁ and TOC as well as relationship curve between light hydrocarbon recovery coefficient and R_o are established to obtain the original S₁ content. In addition,four key parameters for the evaluation of pure shale oil resources (S₁, TOC, R_o and shale thickness) and another three for interlayer shale oil resources (cumulative thickness of shale interlayer, porosity and oil saturation) are determined, and the lower limits of these parameters are formulated accordingly. By applying the unified assessment method and standard, typical cases of shale oil resource assessment are studied,including the Cretaceous Qingshankou Formation in the northern Songliao Basin, Triassic Yanchang Formation in Ordos Basin, and Permian Lucaogou Formation in Junggar Basin. The evaluation results show that the geological resources of pure shale oil in the first member of Qingshankou Formation (Qing 1 member) are 52.23×10⁸ t, with light oil (R_o>1.2%) of 11.18×10⁸ t; The total shale oil resources in the third sub member of the seventh member of Yanchang Formation (Chang 7₃ sub member) are 66.80×10⁸ t, among which the interlayer shale oil resources are 27.73×10⁸ t, and the pure shale oil resources are 39.07×10⁸ t; The total shale oil resources in Lucaogou Formation are 15.62×10⁸ t, among which the interlayer shale oil resources are 11.99×10⁸ t, and the pure shale oil resources are 3.63×10⁸ t.
