摘要：

中国西部—青藏区包括了甘肃、青海、新疆、西藏等4个省(区)及四川省西部的区域。该区分布有许多大型沉积盆地，油页岩成矿条件优越，油页岩资源十分丰富。资源评价结果表明, 西部—青藏区油页岩资源量为1 952.63亿t,其中查明资源量 22.24亿t,占全国查明资源量的4.44%；潜在资源量1 930.39亿t，占全国油页岩潜在资源量的28.82%，表明西部—青藏区油页岩勘查程度较低，油页岩勘查潜力巨大。油页岩有机成因类型为腐泥型、腐殖腐泥型和腐殖型。形成于湖泊、湖泊—沼泽及泻湖相环境中,油页岩品质较好,大部分含油率大于10%。油页岩在上古生界、中生界、新生界均有分布,油页岩资源形成时代由北向南逐渐变新。经油页岩勘查目标优选, 优选出西部—青藏区最有利油页岩勘查目标区9个,有利油页岩勘查目标区7个, 较有利油页岩勘查目标区4个。

Abstract:

The western China to Qinghai-Tibet area covers Gansu, Qinghai, Xinjiang, Tibet and western Sichuan, where distributes lots of sedimentary basins hosting abundant oilshale resources. The oilshale resources reach to 195.263 billion tons in these areas, about 4.44% of the total in China, the oilshale potential is 193.039 billion tons, 28.82 of the total in China, indicating a big potential in these areas. The genesis of oilshale can be classified as sapropel , humosapropelic and humic, formed in lakes, marshes and lagoons, where the oilshale is quality, most more than 10% in oil-bearing rate. The oilshales are distributed in the upper Paleozoic, Mesozoic and Cenozoic, becoming younger southwards in oilshale formation ages. This paper, based on a prioritization of exploration targets, selects 9 target areas as most favorable areas, 7 as favorable areas, and 4 as sub-favorable areas.

Key words: western China to Qinghai-Tibet area; oilshale resources; exploration targets; oil-bearing rate
