摘要：

松辽盆地根据高势面盖层组合状况,划分出3个含油气系统,这样的划分已落后于松辽盆地的现有勘探水平。因此,须在每一含油气系统内进一步细分出更利于勘探的油气单元。所谓准含油气系统即是指介于含油系统与成藏组合之间的聚油单元,其核心是该单元具有类似的生、储、盖等静态成藏条件及相同的运、聚动态过程。松辽盆地中含油气系统以向上排烃、侧向运移为主,因聚集方式不同可划分出3个准含油气系统:以汇聚型为主的大庆长垣准含油气系统,以侧向运移聚集为主的泰康英台准含油气系统及以发散性聚集为主的南部准含油气系统;下部含油气系统以向下排烃、垂向运移为主,因聚集方式的不同按区域分布进一步划分为4类准含油气系统:以注入式滞留型、发散性为主的三肇及齐家-古龙-长岭准含油气系统,以汇聚型为主的大庆长垣及扶新-朝阳沟准含油气系统。

Abstract:

Three petroleum systoms are divided according to high potential surface caprock combination in Songliao Basin.This division is lags behind the present exploration of the basin.So it's necessary to subdivide each petroleum system into more favourable petroleum units.The so called quasi-petroliferous system is actually a kind of hydrocarbon accumulation unit that between the petroliferous system and hydrocarbon pool-forming assemblage.The core of the oil accumulation unit is that it has similar static pool-forming condition such as oil generation-reservoir-caprock and dynamic process of oil migration and accumulation.The middle petroliferous system of Songliao Basin is dominated by oil and gas upward expulsion and lateral migration.This system could be subdivided into three quasi-petroliferous systems according to different hydrocarbon accumulation ways:Daqing Placanticline quasi-petroliferous system of confluent type;Taikang-Yingtai quasi-petroliferous system dominated by lateral migration and accumulation;the south quasi-petroliferous system of divergent accumulation.The lower petroliferous system of the basin is dominated by downward expulsion and vertical migration,and could be subdivided into 4 types of quasi-petroliferous systems:Sanzhao,Qijia,Gulong,Changling subsystems of detained and divergent accumulation;Daqing Placanitcline and Fuxin-Chaoyanggou subsystems of confluent accumulation.

Key words: quasi-petroleum system, oil accumulating unit, accumulation way, Songliao Basin
