中国油页岩资源现状

2004～2006年我国首次开展了全国性油页岩资源评价工作。为了更好地揭示我国油页岩的分布规律及特征，按不同地区、不同层系、不同含油率、不同埋深和不同地理环境进行了归类汇总。评价结果表明，我国油页岩资源丰富,分布范围广，分布在20个省和自治区、47个盆地，共有80个含矿区。全国油页岩资源为7 199.37 亿t，页岩油资源为476.44 亿t，页岩油可回收资源为119.79 亿t。全国油页岩主要集中分布在东部区和中部区，东部区油页岩资源为3 442.48 亿t，中部区油页岩资源为1 609.64 亿t，青藏区油页岩资源为1 203.20 亿t，西部区油页岩资源为749.94 亿t，南方区油页岩资源为194.61 亿t，分别占全国油页岩资源的48％、22％、17％、10％和3％。全国油页岩主要集中分布在中、新生界，其中，中生界油页岩资源为5 597.92 亿t，新生界油页岩资源为1 052.31 亿t，分别占全国油页岩资源的77.76％和14.62％，油页岩形成时代从西北至东南方向逐渐变新。我国油页岩含油率中等偏好，其中含油率＞5％～10％的油页岩资源为2 664.35 亿t，含油率＞10％的油页岩资源为1 266.94 亿t，分别占全国油页岩资源的37％和18％。我国油页岩埋藏深度较浅，埋深在0～500 m之间的油页岩资源为4 663.51 亿t，埋深在500～1 000 m之间的油页岩资源为2 535.86 亿t，分别占全国油页岩资源的64.78％和35.22％。我国油页岩主要分布在平原和黄土塬地区，分布在平原地区的油页岩资源为3 256.53 亿t，分布于黄土塬地区的油页岩资源为1 562.86 亿t，分别占全国油页岩资源的45％和21％。油页岩资源巨大的盆地有:松辽盆地、鄂尔多斯盆地、准噶尔盆地，占全国油页岩资源的76.79％。

The Situation of Oil Shale Resources in China

The first national evaluating of oil shale resource has been completed with consummation, which had lasted for two years from 2004 to 2006. The evaluation results were classified based on the differences of districts，buried stratum，oil yield，buried depth and geography environment in order to discover the distributing principles and features of oil shale. The evaluation result indicates that the oil shale resources are rich in China and distribute in a broad range. There are about 80 mines have been found in 20 provinces and 47 basins by now. In China, the total oil shale resources and shale oil resources are estimated at 7 199.37×10⁸ tons and 476.44×10⁸ tons， respectively. According to the evaluation result, Most of oil shale resource in China is enriched in the east and the mid area. Oil shale resource of the east area， the mid area， the Qinghai and Tibet area， the west area and the south area dedicate 48%(3 442.48×10⁸ tons)，22%(1 609.64×10⁸ tons)，17%(1 203.20×10⁸ tons)，10%(749.94×10⁸ tons)and 3% (194.61×10⁸ tons) of the total resources of China, respectively. In China, oil shale resource is enriched in Mesozoic and Cenozoic strata, which dedicates 77.76%(5 597.92×10⁸ tons) and 14.62%(1 052.31×10⁸ tons) of the total resources of China, respectively. The age of the oil shale in the northwest is younger than the southeast. The grade of oil shale (oil yield) ranges from middling to good. Oil shale resources of middling grade (>5%~10%) took 37% (2 664.35×10⁸ tons) of national total resources and the good grade (exceed 10%) took 18% (1 267×10⁸ tons). About 64.78%(4 663.53×10⁸ tons) resources are buried from the depth of 0 m to 500 m and 35.22%(2 535.86×10⁸ tons) were buried between the depth of 500 m to 1 000 m. In China, oil shale resource is enriched in the plain and loess land which took 45% (3 256.53×10⁸ tons) and 21%(1 562.86×10⁸ tons) of the national total resources, respectively.Oil shale basins with large resources are Songliao Basin,Ordos Basin and Jugger Basin,their resources covers 76.79% of the countrywide resources.
