摘要
利用含氮化合物定量分离分析技术,研究了双南油田原油中中性氮化合物的分布、组成与浓度变化。分析结果表明原油中烷基咔唑系列呈现富和贫C-1位烷基取代2种模式,这与辽河盆地西部凹陷沙河街组烃源岩中烷基咔唑系列较好的可比性。依据原油甾萜烷成熟度参数、含氮化合物浓度和运移参数的变化特征,结合区域地质背景认为清水凹陷是双南油田的主要油源区。油气的运移方向是从双201井向双110-1井和双202井推进。
The distribution, composition and concentration changes of neutral nitrogen compounds in crude oil from Shuangnan Oilfield are studied by quantitatively separating and analyzing the nitrogen compounds. The results showed that there are two distribution models of alkylcarbazole series with high and low abundance of C-1 substitutes in those oils, corresponding to Shahejie Formation source rocks from the west depression of Liaohe Basin. Based on the changes of maturity parameters, such as sterane and terpane, the concentrations of neutral nitrogen compounds and migration parameters in the crude oils, and combined with the backgrounds of regional geology, the crude oil in Shuangnan Oilfield is mainly derived from Qingshui Sag. The migration direction of crude oil is from well S201 to Well S110-1 and Well S202.
