目前在油气勘探开发领域对于石油地质基础研究概念的理解上存在很大误区,地质学家把地质基础研究、有机地球化学家把有机地球化学特征作为了石油地质基础研究。应该把成盆、成烃、成藏作为一个统一的、相辅相成的过程来探讨石油地质基础研究的问题,这种理解与含油气系统概念相似。由于现有体制和机制的原因,目前开展的石油地质基础研究缺乏齐全准确的基础资料和扎实可靠的基础工作的支撑,无法实现理论创新。石油地质学家应把盆地的石油地质基础研究重点放在认真分析盆地在持续沉降、整体上升和全面萎缩3个发展阶段的演化特征,以及与成烃和成藏过程的内在关联方面,这也是含油气盆地研究的理论创新方向。建议应从3个方面开展成烃的基础研究。而成藏研究的正确方向应当是研究在盆地整体上升阶段和全面萎缩阶段烃源岩与圈闭之间的压力差。
At present, there is a big misunderstanding about the concept of petroleum geological basic research in the field of oil and gas exploration and development. Geologists have taken organic geochemical characteristics as the basic research of petroleum geology by geological basic research and organic geochemists. The basin-forming, hydrocarbon-forming and hydrocarbon accumulation should be treated as a unified and complementary process to explore the basic research of petroleum geology, which is similar to the concept of petroleum system. Due to the existing system and mechanism, the current research on petroleum geology lacked the complete and accurate basic data and solid foundation work, which failed to achieve theoretical innovation. Petroleum geologists should focus their research on the petroleum geology of the basin to carefully analyze the evolution characteristics of the basin in the three stages of continuous subsidence, overall ascent and total atrophy as well as the intrinsic correlation with the process of hydrocarbon generation and accumulation, which is also Theoretical innovation of researching petroliferous basins. It is suggested that basic research on hydrocarbon generation should be carried out in three aspects. The correct direction of hydrocarbon accumulation research should be to study the pressure difference between source rocks and traps in the basin ascending stage and the full shrinking stage.
