浅谈四川盆地油气勘探的几点历史经验

Cases Study of Oil and Gas Exploration Experience in Sichuan Basin

四川盆地是一个多旋回的叠合盆地。现有的勘探成果表明,盆地油气资源丰富,纵向上多个层位含气,横向上各油气分区均有多个大-中型气田分布,具有明显的满盆含气,多层系立体勘探潜力。正确认识勘探历程中的利弊因素,关键还是要充分了解地下地质情况,丰富油气成藏条件的理论体系。进入二十一世纪以来,四川盆地海相和陆相油气勘探均有重大突破,先后发现了普光、广安、安岳等大型气田,预示着四川盆地还有巨大的勘探潜力。

The Sichuan Basin is a multi-cycled superimposed basin.Existing oil and gasexploration results show that Sichuan Basin is rich in oil and gas resources,with multiple layers containing gas and many large-medium gas fields distributingin each oil and gas zone.The key to correctly understand the favorable and disadvantage factors of the exploration process is to fully understand the underground geological conditions and enrich the theoretical system of oil and gas accumulation conditions.Since the beginning of the twentieth century,major breakthroughs have been made in marine and terrestrial oil and gas exploration in Sichuan Basin,with large gas fields such as Puguang,Guang'an,Anyue have been discovered,indicating that there remains huge amount of oil and gas resources to be exploited in Sichuan Basin.
