摘要： 楚雄盆地属长期发展的叠合型含油 气盆地,沉积了海相、海陆交替相和陆相三大类多套含油气组合;盆地及其四周形成了超岩石圈、岩石圈断裂、壳断裂、基底断裂和盖层断裂体系,创造了优良的油气运移通道;具备了生物成因与非生物成因两类多套油气源叠合富集的石油地质条件;形成了以背斜为主的多种圈闭类型;盆地后期保存条件好;是一个油气资源非常丰富的中型含油气盆地。

Abstract: Chuxiong basin in Yunnan province is a long-term developing and superimposed petroliferous basin with multi-deposits of marinefacies, continental-marine interaction facies and continental facies. There exist translithospheric fracture, lithospheric fracture, crustalfracture, basement fracture and caprock fracture within and around the basin. They prov ide favorable passages for oil and gas migration. Thestudy shows that it has well conditions in petroleum geology for forming a multi-superposition petroleum system with biogenetic and non-biogenetic origins and multiple types of traps dominated by anticline as well as good preservation in late period of the basin. It is concludedthat it is a medium-scale petroliferous basin with very rich hydrocarbon resources.

Key words: Yunnan, Chuxiong basin, origin, fracture
