摘要
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 。
Pyrrolic nitrogen compounds are used as “tracers” for investigating oil migration and accumulation of Xinzhan oilfield in Songliao basin. The results of analyses on some parameters of pyrrolic nitrogen compounds in oils indicate that oils of the field likely came from Qijia Gulong sag and migrated in short distance. It is suggested that the main charging point should be around Yi 411 and Da 415 wells located between two dominant faults of northern Da'an nose like structure. The main pathway of oil migration is fault, and the lateral migration dire ction of the oil is controlled by the faults along the tread of the faults from northwest to southeast.
