摘要
油气系统划分是油气系统特征描述和研究的前提和基础。在明确油气系统概念的基础上 ,按照一个盆地有几套成熟烃源岩就有几个油气系统的划分原则 ,根据松辽盆地南部有效烃源岩的发育和分布、油气分布和油气源对比成果 ,并结合盆地的构造特征及储集层分布特征 ,将盆地南部中浅层划分为 2个油气系统和 1个复合油气系统。在详细分析 3个油气系统特征的基础上 ,得出以下结论 :K1qn—P G F Y油气系统烃源岩质量好 ,演化程度高 ,为成熟—高成熟的油气系统 ;K1n1 2 —H油气系统演化程度低 ,为低熟—成熟的油气系统 ;K1qn k1n1 2 —S复合油气系统为成熟的油气系统。图 6表 2参
Petroleum system division is the precondation and base of petroleum system stu dy. In the light of conception of petroleum system and based on the principle th at if a petroleum basin has several sets of mature source rocks, there exist sev eral petroleum systems. The middle upper strata of southern Songliao basin are divided into two petroleum systems and one composite petroleum system, according to the development and distribution of effective source rock, oil and gas distr ibution and the hydrocarbon source c orrelation for the south of Songliao basin, and combined with the structural cha racteristic and reservoir distribution of the basin. From the analysis of three petroleum systems′ characteristics in detail it can draw conclusions that: (1) F or K 1q n-P G F Y petroleum system, source rock quality is good, evolution degree is high. So this is a mature and high mature system. (2) For K 1n 1 2 -H petroleum system, evolution degree is low. So this is a low mature and h igh mature petroleum system. (3) K 1q n K 1n 1 2 -S petroleum syste m is a mature composite system.
