摘要
根据两次资源评价结果的分析和对比,认为值得对古生界进行大规模油气勘探。分析了中国海相油气勘探滞后的原因是地史发展的顺序为先海后陆和海相沉积深度比陆相的大。归纳阐述了适用于海相沉积与陆相沉积的10条基本石油地质认识,指出了我国海相沉积深度大、年代老、生油争议多、气比油多、遭破坏多等特点,建议开展区域地质、碳酸盐岩生油、古隆起带、逆掩断层带、盐下油气、碳酸盐岩储集性、油藏破坏与保存的关系、新技术与新方法等8个方面的研究。
Based on analysis and correlation of the result of secondary resource assessment,it is believed that it's worth to carry out a large scale of petroleum exploration in Paleozoic.The paper describes 10 basic petroleum geological understanding of marine and continental deposit.It is pointed that the marine sequence is characterized by deep burial,old age,more gas than oil,more argument in hydrocarbon generation,even more destruction.It is considered that it may be significant to carry out 8 studies on regional geology,hydrocarbon generation in carbonate rock,paleo-uplift zone,thrust-faulted zone,oil-gas in sub,salt,carbonate rock reservoir,oil-pool destruction and preservation,new technology and method and so on.
