摘要
文中分析了盆地热演化过程中有关的分子有机化学反应所遵从的规律,并推导了在地质演化过程中求解有关的分子有机化学反应生成物的公式。研究了甾、萜类化合物中甾烷C_29的[20S]/[20R]+[20S]和蕾烷C_32的[22S]/[22R]+[22S]的异构化反应和甾族化合物从单芳环向三芳环的芳构化反应的理论计算问题,并把这理论初步应用于南海北部张裂盆地中,得到较好的效果。
The.behaviour of organic chemical reactions in thermalhistory of stretchedbasin weredescribed and the formulae concerned with these reactions werederived.The calculations forisomerization of C_29 steranes at C_20,isomerization of C_32 hopanes at C_22 and aromatization ofC_29 C-ring monoaromatic to triaromatic steroid hydrocarbons were studied. We applied thesetheories to the stretched basin in northern South China Sea,and the calculated the progressof these reactions agrees well with the data observed in the basin.
