中国古生代海相油气田发现的回顾与启示

1984年在塔里木盆地部署的沙参2井实现了中国古生代海相油气田首次重大突破,成为我国油气勘探史上的重要里程碑,宣布了塔河大油田的诞生,之后又发现数个古生代油气田,到中国古生代海相成油理论的建立等,这一过程充分体现了自主创新的过程,笔者对其进行了较系统的总结和回顾,得到的启示是:加强基础研究是大油气田发现的前提;开拓创新是大油气田的关键;技术进步是大油气田发现的必要条件;坚持勘探、不断实践是大油气田发现的保证。

Review and revelation of oil/gas discoveries in the Paleozoic marine strata of China

In 1984, the Shacan-2 well, positioned in Tarim basin, flowed for the first time with large amount of oil and gas, marking the discovery of giant Tahe oilfield. It was not only the first significant breakthrough in exploration of the Paleozoic strata, but also an important milestone in Chinese oil/gas exploration history. Since then, several other Paleozoic oilfields were discovered and the theory of hydrocarbon reservoiring in the strata in China was established. It is a period characterized by independent innovations in exploration of the Paleozoic marine strata. Based on a systematic summaries and review of the time, the article concludes that more large oil/gas discoveries depend on many factors, among which deeper basic researches are the precondition, innovations and creativity are the key, technology advancements are the necessary conditions, and continuous explorations and practices are the guarantee.
