以中性含氮化合物的分馏作用确定低熟油运移路径

Determining Migration Pathway of Low Maturity Oil from Fractional Distillation of Neutral Nitrogen Compounds

中性含氮化合物相对含量的变化可用来判断油气运移的路径和方向,对于未熟、低熟油也不例外。对高升油田产出油中的苯并咔唑和烷基咔唑类化合物的分析表明,高升油田原油的运移方向是由南向北,即从陈家洼陷(油源区)到雷家地区,再到高二、高三区,最后到高一区,与该区饱和烃成熟度参数的分布趋势相同。

The relative abundance of neutral nitrogen compounds can be used to identify the migration pathway and direction of petroleum,as well as immature and low mature oil.The analysis of benzocarbozole and alkylcarbarzole compounds in the oil form Gaosheng Oilfield showed a migrated direction from south to west.That was the oil migrated from Chenjia depression(source area) to Leijia area,to Gao2+3 area and lastly to Gao1 area,which was consistent with the distribution of saturated maturity parameters in the same areas.
