异常热作用(如火山喷发、岩浆侵入)对沉积有机质演化的影响已被广泛地受到重视,目的在于了解这种热烘烤所引起有机物质化学结构的变化,从而对煤和石油的演化能获得较好的认识.研究表明,这种异常热作用对油页岩的主要影响则表现为石油烃的生成以及其从邻近岩层的排出,残留烃具有高芳香度的特征.本文以我国辽河盆地东部凹陷下第三系烃源岩为研究对象,首次揭示了该区域早第三纪火山活动对油气生成、聚集的影响.
The effects of anomalous thermal effects such as volcanic eruptions and magmatic intrusion on the evolution of sedimentary organic matter have been widely recognized for the purpose of understanding the chemical structure of organic matter caused by this thermal baking and hence the evolutionary energy of coal and petroleum Better understanding.Research shows that the main effect of this abnormal thermal effect on oil shale is the formation of petroleum hydrocarbons and their discharge from adjacent formations and residual hydrocarbons with high aromaticity.In this paper, The Tertiary source rocks in the depression have been studied for the first time, revealing for the first time the impact of early Tertiary volcanism on hydrocarbon generation and accumulation in this area.
