摘要：

位于鄂尔多斯盆地东南部的陕西铜川、宜君和黄陵一带赋存着丰富的油页岩资源。主要的含油页岩层位是中—晚三叠世延长组下段上部，具体形成时间为中三叠世晚期。野外观察发现，油页岩露头主要分布于铜川—宜君—黄陵一带，主矿层厚度一般为2~36 m。测得含油率为 1.8%~13.7%，发热量为1.66～11.45 MJ/kg，推测干酪根类型为I-II1，产烃率为400 kg/t，中等偏好，页岩油（相当于原油）资源量约100×108 t，储量近亿吨。宏观和微观资料表明，该区油页岩是在淡水、近岸、强还原、富含有机质的沉积环境下形成的，属于大型内陆湖盆的半深—深湖相，埋藏浅，储量较大，交通条件好，如果在适当时机开发，不仅可获得初步经济效益，也可为鄂尔多斯油页岩的开发利用获取开拓性的经验。该区油页岩矿位于西部最大城市西安市附近，开发利用的意义重大。

Abstract:

Oil shale is becoming a research hot point with decreasing increasingly in hydrocarbon resources at present. There are abundant oil shale resources in Ordos basin. Oil shale resources in Ordos basin account for 60% of that in middlewest China and rank the first among all basins in China. The main bed of oil shale is the upper part of lower segment of Yanchang Formation （Ty）, and was formed in late stage of Middle Triassic period. According to field observations, the outcrops of oil shales are mainly distributed in TongchuanYijunHuangling. The thickness of main ore beds is generally 2-36 m. The oilbearing ratio range is from 1.8% to 13.7%;caloric value range is from 1.66 to 11.45 MJ/kg and type of kerabitumen is I-II₁; ratio of hydrocarbon-producing is 400 kg/t（moderatebetter）. The proved resources amount is around 100×108 t and reserves amount is closely 1 ×108 t in this area. It is pointed out that oil shales were formed in depositional environment with fresh water,nearshore,powerful reduction,rich content of organic material according to different data and belong to semi-deep lacustrine facies in large inland lake. The burial of oil shale is shallow; reserves of oil shales are large;and traffic condition is advantageous in the area. If oil shales are well developed, not only preliminary economic benefits may be acquired, but also precious experience in developing oil shale in Ordos basin may be gained. Besides, oil shales in Tongchuan-Huangling are the nearest to Xi-an, having great significance for developing.
