摘　　要：盆地经历多期构造运动,燕山期是油气藏关键时刻。晚燕山期后上覆K2-E地层成为新的区域盖层,喜马拉雅运动的挤压作用加强和改造了原先形成的圈闭,使油气重新分配,形成新的油气保存单元。将楚雄盆地现今油气保存单元划分为持续型、残留型、改造型及重建型四种基本类型,并对其进行综合评价。This basin has experienced several structural movements. Yanshanian is the key period of the oil - gas formation. After the Late Yanshanian, the overlying K2 - E became the new regional covering strata. The pressing of Himalayan movement has strengthened and reformed the previous trap, which caused the oil -gas to be distributed anew and the new oil -gas preservation unit to be formed. The present oil - gas preservation units in Chuxiong basin are divided into 4 basic types, ie. , successive; relict; reformed and reconstructed, which are comprehensively evaluated in this paper.
