本文分析了塔里木盆地轮南海相、松辽盆地新站淡水湖相、朝阳沟—长春岭淡水—半咸水相、柴达木盆地尕斯库勒盐湖相原油中吡咯类化合物的分布特征，发现不同成因类型原油中吡咯类含氮化合物的丰度与相对分布有着显著的差异。文中进一步探讨了沉积环境、成熟度、母源、运移作用对该类化合物的可能控制作用。结果表明原油中吡咯类化合物的丰度与相对分布可能受控于多种地球化学因素，运移分馏作用与沉积环境可能是控制该类化合物的主要因素。成熟度、原始生源对该类化合物也有一定的影响。非烃中吡咯类含氮水合物在指示油气运移方向、指相以及成熟度方面有着潜在地球化学意义。
In this paper, the distribution characteristics of pyrrole compounds in Lunnan marine facies in Tarim Basin, fresh water facies of Xinzhan Station in Songliao Basin, Chaoyanggou-Changchunling freshwater-brackish water facies, and Gaskul Salts Lake crude oil in Qaidam Basin were analyzed. The abundances and relative distributions of pyrrole nitrogen compounds in crude oil of different genetic types are significantly different. The paper further explores the possible controlling effects of sedimentary environment, maturity, maternal and migration on these compounds. The results show that the abundance and relative distribution of pyrrole compounds in crude oils may be controlled by a variety of geochemical factors. The migration and fractionation and sedimentary environment may be the main factors controlling these compounds. Maturity, the original source of these compounds also have a certain impact. Pyrrole nitrogen-containing hydrates in nonhydrocarbons have potential geochemical significance in indicating hydrocarbon migration direction, facies, and maturity.
