四川盆地普光大型气田的发现与勘探启示

Discovery of the Large-scale Puguang Gas Field in the Sichuan Basin and Its Enlightenment for Hydrocarbon Prospecting

普光气田是四川盆地近期发现的规模最大、埋藏最深、资源丰度最高的气田。在对普光气田的勘探及气藏基本特征研究的基础上,笔者总结了普光大型气田的发现与勘探启示,即成熟盆地的勘探需要有新思路;勘探技术是促进勘探发展的技术保障;大型富油气盆地油气成藏类型多,成藏条件复杂,立体勘探能有效降低勘探风险。

The Puguang gas field recently discovered in the Sichuan basin is the largest and deepest gas pool, and of the greatest abundance in resource. Based on the course of exploration and discovery as well as the basic features of the field, the discovery of the field and its enlightenment for hydrocarbon prospecting have been summarized, that is, new thoughtways are needed for the exploration of mature basins, survey techniques are the guarantee for accelerating the exploration, and exploration risks can be effectively reduced by three-dimensional exploration for basins rich in hydrocarbon and with various types and complicate conditions of reservoir formation.
