| 摘 要： | 陆良盆地是云南第三系沉积盆地的典型代表。盆地的形成过程决定了第三系含气系统的形成过程。盆地第三系有一个含气系统，即Ｎ２ｃ２－Ｎ２ｃ３（！）含气系统。上第三系茨营组二段（Ｎ２ｃ２）为主力烃源岩，三段（Ｎ２ｃ３）为优势储集岩，而Ｎ２ｃ４为区域盖层。Ｎ２ｃ２－Ｎ２ｃ３（！）含气系统的关键时期是距今１．６４Ｍａ，圈闭形成于Ｎ２ｃ１－Ｎ２ｃ４，油气生成－运移－聚集发生在Ｎ２ｃ２至今。

| Abstract: | Luliang Basin is a typical representative of the Tertiary sedimentary basins in Yunnan Province. The formation of the basin results in the formation of the gas system in the basin. There is a gas system in the basin, i.e. the N 2 c 2 - N 2 c 3 gas system. The Second Member of the Neogene Ciying Formation (N 2 c 2) is the main source rock, the Third Member of the Neogene Ciying Formation (N 2 c 3) is the main reservoir rock, and the Forth Member of the Neogene Ciying Formation ( N 2 c 4) is the main cap rock. The critical time of the gas system is about 1.64 Ma. The traps in the basin formed during N 2 c 1 - N 2 c 4. The generation migration accumulation of the gas has occurred from N 2 c 1 to today. |
