摘要:烃源岩排烃作用的研究在20世纪80年代以后取得了很大进展,主要体现在对烃源岩的排烃机理及控制因素的分析、煤成油排驱的理论研究及勘探突破、幕式排液的探讨及压实—压裂双端元排烃模型的建立等方面。在针对研究现状分析的基础上,提出了几点研究方向及展望:加强对烃源岩剖面排烃特征的高分辨率研究,建立压实—欠压实—压裂三端元排烃模型,对存在严重非均质性的烃源岩进行烃源岩排烃分级评价,深入探讨排烃与油气成藏的关系。
关 键 词:烃源岩;排烃作用;幕式排液;排烃模型

Abstract: The investigation on hydrocarbon-expulsion from source rocks hasmade big advances in the following aspects: the mechanism and key factors on hydrocarbon expulsion, the research on the oil derived from coals and its exploration break, episodic hydrocarbon-expulsion, and establishment of compaction-fracturing model of hydrocarbon-expulsion. On the basis of current situation on the investigation, the paper brings forward several suggestions and prospects of the research: strengthen the high resolution research on the characteristics of the hydrocarbon-expulsion in the section of source rocks, set up the hydrocarbon-expulsion model including three phases ( compaction, uncompaction and cracking) , evaluate hydrocarbon2expulsion on classification of the anisotropic source rocks, and discuss the relation between hydrocarbon-expulsion and hydrocarbon accumulation.
Key words: Source rocks; Hydrocarbon-expulsion action; Episodic hydrocarbon expulsion; Model of hydrocarbon-expulsion.
