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。

简介：基于确定的数学模型和图形的解释，一个新方法，被用来在一由紫外线光谱技术生产混合很好计算单个地区的生产的贡献，被建立了。标准板用作为X轴作为Y轴和波长人工地提出的样品油的消光系数E被拉。从样品油的紫外分析导致混合的井的曲线被插入到标准板并且比较。在生产混合很好的每个单个地区的比例与接近人工地提出的样品油的曲线的曲线的比例是相同的。在井QHD32-6-3地里，例如并且用这个方法拿A22很好，一个单个地区的生产贡献被计算。Theresult证明Nm4地区是一个主要“贡献者”，Nm4地区的比例是70%，并且Nm1地区的是30%。紫外线光谱技术提供了监视生产贡献的一种新reservoirgeochemical技术，特别为简历降级的重油，而是它有某限制，就取决于GC指纹技术。
