| 摘 要： | 云南楚雄盆地是扬子板块西南缘的中新生代含油气盆地，具有复杂的构造、沉积演化历史．应用沉积波动过程分析方法，研究了楚雄盆地演化过程中的主要周期，得出楚雄盆地存在3个一级沉积波动周期(220Ma)、6个二级沉积波动周期(100Ma)、9．5个三级沉积波动周期(45Ma)以及高频波动周期(10Ma、5Ma)．通过对不同波动单元的波动曲线对比，得出楚雄盆地构造沉积演化规律：在古生代沉积中心位于盆地东部的云龙凹陷；中生代早期，沉积中心具有自西南向东北，由盆地边缘向中心迁移的规律，晚期受构造运动影响，沉积中心有自东北向西南回迁的趋势。

| Abstract: | Chuxiong basin is a Mesozoic-Cenozoic petroleum basin in the southwestern margin of the Yangtze plate, which has a complex tectonic and sedimentation history. By using the analysis method of wave processes, major evolution cycles of the Chuxiong basin have been studied. This study shows that there are three first-order sedimentary cycles (220 Ma), six second-order sedimentary cycles (100 Ma), nine and a half third-order sedimentary cycles (45 Ma) and high-frequency cycles (10 Ma, 5 Ma). By comparison of the wave curves in different wave units, we gained the tectonic-sedimentation regularity: the sedimentation center in Paleozoic was in the Yunlong Depression in the eastern part of the basin. Early in the Mesozoic, the sedimentation center migrated from southwest to northeast and from basin margin to basin center. In late Mesozoic, the sedimentation center displayed a reversed migration trend from northeast to southwest. |
