对辽河油田曙光欢喜岭潜山带沙三段（Ｅｓ３） 和沙四段（Ｅｓ４） 典型的未成熟源岩样品进行了高温高压干体系的生排烃热压模拟实验。研究结果表明：３００ ～４００ ℃（Ｒｏ ＝０ ．３３ ％ ～１ ．３０ ％ ） 为该区域烃源岩的主要生排烃阶段；沙四段具有更好的生排油潜力，可能是曙光－ 欢喜岭潜山带较好的烃源岩；生排烃作用对排出油和残留油中生物标志物的组成具有明显的影响，在油／ 源对比时应特别注意。
The typical immature source rock samples of Es3 and Es4 in the ShuguangHuanxiling submarine zone of Liaohe Oilfield were simulated by the experiments of heat and expulsion heat pressure generation of high temperature and pressure dry system. The results show that: 300 ~ 400 ℃ (Ro = 0.33% ~ 1.30%) is the main hydrocarbon generation and expulsion stage of source rocks in the area; Es4 has better potential for oil generation and discharge, which may be Dawn - The Huanxiling mountainous area is a good source rock; the effect of hydrocarbon generation and expulsion on the composition of biomarkers in discharged oil and residual oil has a significant impact, and special attention should be paid when comparing oil / source.
