鄂尔多斯盆地面积32万平方公里。石炭系一下二迭统地层分布广泛,煤系地层发育,具有形成煤成气(油)的地质条件;其上二迭统陆相地层是储、盖层。上古生界是一套下生(气、油)上储(储油层)的成油组合。经二十几年综合勘探,发现地面油苗及井下油气显示分布广、类型多,并钻出一些工业气井。经油源对比认为其气、油来自煤系地层。初步预测含煤面积约25万平方公里,为世界十大含煤盆地之一,具有丰富的成气母质,是我国勘探煤成气最有远景的地区之一。
Erdos Basin covers an area of 320,000 square kilometers. The Carboniferous Formation is characterized by a wide distribution of Permian strata and the development of coal measures strata that have the geological conditions for the formation of coal-to-gas (oil). The Upper Permian continental facies are reservoirs and caprocks. The Paleozoic is a set of oil (oil and gas) reservoir (reservoir) into the oil portfolio. After more than twenty years of comprehensive exploration, it was found that the oil spill on the surface and the oil and gas in the underground show a wide distribution, many types and some industrial gas wells have been drilled. The oil source that the gas contrast, oil from the coal formation. It is one of the top ten coal-bearing basins in the world that is initially predicted to have a coal-bearing area of about 250,000 square kilometers and is rich in gas and gas parent materials. It is one of the most prospective areas for exploration of coal-forming gas in China.
