摘要

通过对长岭断陷东岭斜坡带烃源岩埋藏史、地温史、有机质成熟度史、生烃率演化、累积生烃量演化等特征的研究，认为该区火一段烃源岩分别在火石岭组沉积末期和盆地坳陷期发生过2次大规模生排烃作用:第1期生排烃在火石岭组内部形成大量自生自储型岩性、地层油藏;第2期生排烃在火石岭组及上覆各套断陷期地层中形成大量构造、构造—岩性油藏和气藏。这2个排烃期对应的油气成藏过程可归纳为断陷期隐蔽油藏成藏模式和坳陷期构造油气藏成藏模式，根据该成藏模式指出长岭断陷中西部的残留洼陷是下一步勘探的有利方向。

Abstract

According to the comprehensive research of source rock burial history,geothermal history,organic matter maturity history,hydrocarbon generation rate evolution and cumulative hydrocarbon generation amount in the Dongling slope belt of Changling fault depression,it is considered that the source rock of K₁h₁ had two massive hydrocarbon generation and expulsion effects,which happened at the sedimentary end of K₁hand during the basin depression stage.The first hydrocarbon generation and expulsion stage resulted in many self-generated and self-stored lithologic and stratigraphic oil reservoirs of K₁h,while the second hydrocarbon generation and expulsion stage resulted in many structural and structural-lithological oil and gas reservoirs of K₁h and its overlying fault-depression formations.The hydrocarbon accumulation process of the two expulsion stages can by concluded to the subtle oil reservoirs accumulation model of the fault-depression period and the structural oil and gas reservoirs accumulation model of the depression period,the next exploration direction can thus be pointed out according to the accumulation models.

Key words： Dongling; Source rock; Thermal evolution; Hydrocarbon generation and expulsion periods; Accumulation model
