简介：中央煤气的地是在中国的Ordos盆的一块著名的大尺寸的煤气的地。然而，在这气体的奥陶纪水库的主要煤气的来源的鉴定回答遗体思索。根据天然气上的很多geo化学的数据和地质的研究，从奥陶纪的天然气的特征和来源在Ordos盆在中央煤气的领域里捱过外壳水库被学习。结果显示从在中央气体的捱过的外壳水库在Ordos盆回答的奥陶纪的天然气有类似的化学药品和同位素组成到高度成熟、在成熟上的干燥气体。导出煤的气体和油类型气体在Ordos盆在中央煤气的领域里共存。前者从更低的古生代的海洋的碳酸盐主要从含碳二叠的煤措施和后者被导出。当油类型气体可以在Ordos盆主要在中央煤气的领域的北、西方、南部的部分被生产时，导出煤的气体发生在中央煤气的领域的东方部分，这被建议。
