摘要
在利用科拉半岛超深钻的实际资料和德国黑森地区地壳深部（地震）地球物理资料，证实中地壳低速塑性层矿化水的存在的基础上，应用深部成烃的基本原理，归纳出深部有机质成烃最终产物的有机化合物组合的特征为：短链正构烷烃多于长链、双环芳烃多于稠环、硫芴（二苯并噻吩）多于氧芴和芴、二环和三环萜烷丰度较高以及原油多为高成熟度等。这些有机化合物特征与塔西南幼陷羊布拉克油气藏和柴达木盆地西北缘冷潮油气藏中的有机质成分进行对比，认为它们的原油都是来自深部中地充低速塑性层，通过滑脱构造带和推覆断裂带，在晚第三纪末期至第四纪运移至有效构造区带成残。
<Abstrart> On the basis of field data from extra-deep drilling in Kera Peninsula and deep crust geophysical data in Black Forest area of Germany as well as verified present of saline water in central crust low-velocity plastic layer, this paper outlined the final products of deep organic matter to form hydrocarbons by applying basic principle for deep-forming hydrocarbon. The constitution of organic compounds is charaterized by that constitutent of short chain normal alkane is more than long chain one, dicyclic aromatic paraffin more than thickening cyclic one, dibenze thiophene more than dibenzofuran and fluorene, dior tri-cyclic terpane is high in abundance, and crude high in maturity. Compare these characteristics with orgboc conshtutes from Yangbulak oil/gas reservoirs in Southwest depression of Tarim basin and Cold lake reservoirs in northwest Qaidam basin, it is believed that their crude oils all came from deep central crust low-velocity plastic players, which migrated in period of late Neogene to Quatemary into favorable structure belts for forming reservoirs along slip structure zones and nappe fault zones.
