摘要
通过对生油岩样品中的中性氮系列化合物含量和组成变化的系统研究 ,指出了含氮化合物的热演化规律和形成机制 ,含氮化合物是沉积有机质成岩演化的产物 ,其含量和组成明显受控于有机质成熟度 ;认为 1- / 4-甲基咔唑、苯并 [a]咔唑 /苯并 [c]咔唑等比值可作为成熟度参数。
Based on a systemic study of the content and composition of various series neutral nitrogen compounds in source rocks, the rules of thermal evolution and generating mechanism have been put forward. Then it is pointed out that nitrogen-containing compounds are the products of rock-forming diagenesis of sedimentary organic matter and that the content and composition are apparently controlled by organic maturity. Accordingly, the ratios of 1-/4-methylcarbazole, benzole carbazole/benzole carbazole and so on may be used as maturity parameters. In addition, the applicability of neutral nitrogen as migration parameters is discussed and it is considered that these migration parameters can only be applied to the same kind of crude oils with similar maturity.
