针对东濮凹陷文留斜坡的石炭二叠系经历了复杂的构造—埋藏史,烃源岩曾发生多次生烃演化的问题,采用构造—埋藏史分析、磷灰石裂变径迹测试和EASY%Ro数值模拟技术,深入研究了石炭二叠系烃源岩的生烃演化历史,探讨了石炭二叠系生烃作用发生的构造期次、生烃强度,结果表明其石炭二叠系烃源岩曾发生过三次重要的生烃作用过程,其分别发生在海西—印支期、喜山早期和喜山晚期,得出了主要生烃作用发生在喜山期的重要结论,并提出了文留斜坡是有望实现东濮凹陷石炭二叠系油气勘探更大突破的有利地区。
The Carboniferous Permian that was in line with the Wenliu slope in Dongpu Depression undergoes complicated tectono-burial history and multiple hydrocarbon generation and evolution have occurred in the source rock. Tectonic-burial analysis, apatite fission track test and EASY % Ro numerical simulation technique, the evolution history of hydrocarbon generation in Carboniferous Permian source rocks was studied in depth. The tectonic period and hydrocarbon generation intensity of hydrocarbon generation in Carboniferous Permian were discussed. The results show that the Carboniferous Permian hydrocarbon source Three important processes of hydrocarbon generation have occurred in the rock, which occurred in the Hercynian-Indosinian, early Himalayan and early Himalayan periods, respectively, and concluded that the major hydrocarbon generation took place during the Himalayan period. The Wenliu slope is a favorable area that is expected to achieve a greater breakthrough in the exploration of Carboniferous Permian in Dongpu Depression.
