摘要构造一古地理在地学基础研究与能源矿产勘查中具有重要的指导意义，国内外学者与勘探家进行了长期卓有成效的探索。本文以四川盆地东北部二叠、三叠系礁滩天然气勘探为例，探讨了沉积相图在油气勘探发现中的重要作用，以及活动论思想在相图编制中的指导意义。结果表明，40余年对四川盆地晚二叠世-早三叠世沉积相的研究，引发了长兴组生物礁、飞仙关组鲕滩天然气勘探的突破与普光、龙岗、元坝等大气田的持续发现，相图的创新与发展带来了油气田大发现的奇迹；将盆地与周缘造山带相结合，探索晚二叠世-早三叠世的原型盆地，表明四川盆地内部及周缘在该时期内构造-古地理环境发生了巨大变迁，台地边缘是礁、滩发育的有利场所，台地内凹陷则是烃源岩分布的有利地区；对沉积盆地的复位与复原有助于矿产资源的预测。新一轮活动论“构造一古地理”研究将基于海量地质调查与油、气、煤勘探等资料，大数据时代下的活动论古地理重建必将带来地学的进步与资源勘查的系列发现。

英文摘要：

Tectono-paleogeography has an important guidance both in earth science basic studies and in energy and deposit exploration. Scholars and explorationists in and outboard have explored for a long period and got fair results. The paper takes the Permian and Triassic reef and shoal gas exploration in northeast Sichuan Basin as an example, and discusses the sedimentary map playing a great role in the series of gas field discoveries, and the mobilistic thought has a thorough significance in making the sedimentary maps. It shows that more than 40 years of study on Late Permian to Early Triassic sedimentary facies has resulted in the breakthrough of gas exploration of the Changxin Formation reefs and the Feixianguan Formation oolitic shoals, and the continuous discoveries of the giant Puguang, the Longgang, and the Yuanba gas fields. The innovation and development of the sedimentary facies maps has given to miracles of big discoveries of a number of gas fields. Combining the basin with the adjacent orogenic belts, the paper focuses on the proto-type basins of Late Permian to Early Triassic. It is shown that the great change for understanding the tectono-plaeogeographic setting during this period around the Sichuan Basin. The platform margin is favorable for the development of reefs and shoals, while the platform sag is the prolific area for the source rocks. To relocate and restore the sedimentary basin is helpful for predication of deposit and resources. The new-round study of moblistic tectono-paleogeography is based upon the much more data of geological surveys, and the exploration data of petroleum and coals. The mobilistic paleo-geography under the big data is to get the progresses in the earth sciences as well as the serial discoveries of resources exploration.
