利用咔唑类非烃化合物作为油气运移示踪剂 ,探讨了松辽盆地新站油田油藏可能的油源和成藏模式。对其原油中吡咯类化合物的丰度、异构体参数的绝对大小与相对变化的研究结果表明 ,该油田原油间运移分馏效应并不显著 ,新站油田原油具有原地与近源性 ,由此推测邻近的齐家—古龙凹陷为其主要的生油灶。根据对吡咯类化合物的分析 ,判断出油气注入点在大安北鼻状构造两条主要断裂间的隆起高部位 ,即英 411及大415一带。油气主要通过断层作垂向运移及侧向扩散聚集。油气的运移、聚集受构造控制 ,首先聚集于构造的高部位 (即北端 ) ,而后作侧向分配。该过程受断裂构造控制 ,两条主要断裂间的油气再次侧向运移方向为北北西—南南东 ,与断层走向一致
Using carbazole non-hydrocarbon compounds as tracer for oil and gas transport, probable oil source and reservoir forming model of Xinzhan oilfield in Songliao Basin are discussed. The results of the study on the abundances of pyrrole compounds in crude oil and the absolute size and relative changes of their isomer parameters show that the migration and fractionation effects of the crude oil in the oilfield are not significant, and the crude oil in the Xinzhan oilfield has in-situ and near- It is inferred that the neighboring Qijia-Gulong depression is its main oil cooker. According to the analysis of pyrrole compounds, it is determined that the hydrocarbon injection point is in the uplifted high part between two major faults of the Daan North nose structure, namely, the Ying 411 and the Greater 415 area. Oil and gas flow mainly through the fault for vertical migration and lateral diffusion and accumulation. The migration and accumulation of oil and gas are controlled by tectonics. They first gather in the high part of the structure (ie the northern end) and then distribute laterally. The process is controlled by the fault structure. The oil and gas between the two main faults once again migrate laterally from north to west-south-south east, consistent with the strike of the fault
