摘　　要：巴彦浩特盆地的石炭系一二叠系属祁连海沉积，与鄂尔多斯盆地发现并探明的靖边、苏里格、榆林、乌审旗等大气田的华北海石炭系一二叠系类比．认为该盆地在含油气层系厚度、烃源岩厚度、储层厚度、储层物性、盖层条件等方面优于鄂尔多斯盆地：在干酪根类型、烃源岩演化的成熟度方面。两者基本相同；在油气圈闭方面各具特色；在含油气层系分布面积和油气远景资源量方面劣于鄂尔多斯盆地。综合分析认为，该盆地具有良好的勘探前菁，是一个值得进一步勘探的地区。采用高分辨率地震勘探，进一步落实圈闭构造，优选发现井井位，是实现盆地油气勘探突破的关键、巴彦浩特盆地石炭系一二叠系具有形成油气藏的基本地质条件。Carboniferous-Permian reservoirs of Bayan-Hot basin are Qilian-sea deposition. Through analogy of Carboniferous - Permian of the North China Sea of large gasfields such as Jingbian, Sulige, Yulin, and Uxin Qi discovered and proved in Ordos basin, it is considered that the Bayan-Hot basin is better than the Ordos Basin in many aspects of the thickness of the oil and gas beating series, the thickness of source rocks, reservoir thickness, physical property of rservoirs, cap rock conditions. The two basins are basically the same in the type of kerogen and evolution maturity of source rock. But it was worse than Ordos basin in the area of oil/gas-beating strata distribution and oil and gas potential resourees. Through comprehensive analysis, it is considered that the basin has a good exploration prospect, is a worthy area for further exploration. By adopting high resolution seismic exploration to further ascertain the trap structure, and to optimize well location of discovery wells, is the key to achieve breakthroughs in oil and gas exploration in the basin. The CarboniferousPermian reservoirs of Bayan-Hot basin have basic geological conditions for the tormation of oil and gas reservoirs, and one of the main areas outside the Ordos basin for the breakthrough of the oil anti gas exploration.
