【摘要】 原油咔唑类化合物分布特征是研究油气运移、成藏规律的有效手段,但对于降解稠油而言,咔唑类化合物能否用于油气运移规律研究的报道目前很少。因此,通过大量的样品分析探讨了影响稠油中咔唑类化合物分布的因素及稠油的运移特征。结果表明,该区原油咔唑类运移参数与原油降解程度和源岩成熟度关系相对较小,主要反映油气的来源和油气运移特征;原油咔唑类化合物参数揭示的油气运移特征是西部斜坡区原油总体处于同一运移系统并呈现由东向西的运移趋势,直线运移距离近100km;油气运移途径可分为2个方向、2种通道,优势运移通道对油气分布有明显的控制作用。最后,提出了下一步在西部斜坡区进行油气勘探的3个有利方向。更多还原

【Abstract】 The research on carbazol compound distribution charac-teristics is a effective way to research on hydrocarbon migration and accumulation; yet as to degraded viscous oil, it is rarely reported that whether carbazol compound could be applied into the research on hydrocarbon migration. Therefore,a large amount of samples have been analyzed to probe into influence on carbazol compound distribution in viscous oil and viscous oil migration characteristics. It proved that carbazol compound migration parameters, less related to oil degradation and source rock maturity, predominantly indicate hy-drocarbon source and migration characteristics. Migration characteristics revealed by carbazol compound is that crude oil in slope zone is general in a single system and stretches from east to west, and linear migration distance reaches 100 km; hydrocarbon migration pathway is classified into two tendencies and two pathways, domi-nant pathway predominate hydrocarbon distribution. Lastly, three potential areas have been figured out to explore.更多还原
