油页岩是一种富含干酪根的沉积岩,通过干馏可获得页岩油,属于非常规油气资源。陕西铜川地区油页岩资源丰富,主要赋存于三叠系延长组,属湖泊型油页岩,分布广泛,油页岩质量相对较好。目前,陕西铜川地区油页岩资源勘探程度很低,查明资源储量约为9×10~8t。为了进一步探明其潜在开发价值,笔者通过矿区地质剖面及相关的地质、钻井资料、样品分析试验和前人研究结果综合分析,陕西铜川地区品质较好的油页岩资源主要分布于趟泥河-列桥含矿带和摩天沟-冯家渠-霸王庄含矿带,按照其赋存状态分为地上和地下两部分,其待查明的资源储量约595×10~8t,油页岩资源是铜川地区继煤炭资源之后最大的化石能源,其产业发展前景巨大。
Oil shale is a kind of sedimentary rock rich in kerogen. It can be obtained by dry distillation of shale oil, which belongs to unconventional oil and gas resources. Shaanxi Shachuan oil shale is rich in resources, mainly in the Triassic Yanchang Formation, a lake-type oil shale, widely distributed, the quality of oil shale is relatively good. At present, the degree of exploration for oil shale resources in Tongchuan area of Shaanxi Province is very low, and the proven resource reserves are about 9 × 10 ~ 8t. In order to further ascertain its potential development value, the author through the geological section of the mining area and related geological, drilling data, sample analysis and comprehensive analysis of previous research results, Shaanxi Tongchuan region better quality oil shale resources are mainly distributed in the Wei River - Leung Bridge ore belt and gutter - Fengjiaqu - Bawangzhuang ore belt, according to their occurrence state is divided into aboveground and underground parts, to be identified reserves of about 595 × 10 ~ 8t, oil shale resources are Tongchuan area following the largest source of fossil fuels, its industrial development prospects.
