摘要
通过对倪丘集凹陷石炭、二叠纪太原组、山西组、下石盒子组及上石盒子组的分散有机质和煤层的综合研究,将分散有机质分为略受氧化的腐泥型、混合型、腐殖型、高度氧化的腐殖型及再旋回型。对其中以腐殖型和高度氧化的腐殖型为主的有机质特征进行研究。从生烃意义的角度,煤可分为富基质镜质体富氢型、富类脂组分富氢型和贫氢型;据富氢程度将煤与分散有机质进行对比,则煤具有更大的生烃能力。
The dispersed organic matter (DOM) and coal in Taiyuan, Shanxi, Xiashihe and Shangshihe Formations of Carboniferous-Permian period, are synthetically studied. The DOM is divided into five types: slightly oxidated sapropelic organic matter (OM) , mixed sapropelic and humic OM, highly oxidated humic OM and re-deposited OM, with the majority being humic and highly oxidated humic OM. Based on the hydrocarbon potential and petrographic composition, coal can be divided into three types: high lipide content, high hydrocarbon poten-tial coal (HLH); high desmocollinite content, high hydrocarbon potential coal (HDH) ; hydrogen poor coal (HP). In comparison with coal,the DOM is oxidated to a higher degree and has a lower lipide conten. It is the coal that has high hydrocarbon potential and is the source rock of the oil that has been found in this region.
