摘要
本文分析了松辽盆地古龙凹陷三口探井嫩一段和青一段地层中某段泥质生油岩在不同油气生成阶段的生烃特征及其排烃效率,结果表明,生油岩所排出的烃大部分是在有机质进入成熟期,油气生成的热催化生油气阶段,其排烃效率达6％～64％,并发现生油岩有负排烃的现象。
<ABSTRACT>: Hydrocarbon generation character and its withdrawal effeciency at different hydrocarbon generation stages of argillaceous source rocks at Nen member 1 and Qing mem-ber 1 of 3 exploration wells in Gulong Sag of Songliao basin is analyzed. It shows that hydro-; carbon withdrawal of source rocks mainly is at the period of organic matter entering matura-tion and hydrocarbon generation thermal cracking stage. Thus,hydrocarbon effeciency reaches 6 - 64%. Nagative hydrocarbon withdrawal of source rocks is found in this area.
