Abstract
Based on the analysis of outcrops,well logs and high resolution seismic reflection data,this paper tries to interpret the depositional enVironment and the seCuence stratigraphy of Jurassic in Kuche depression. The results show that the Kuche basin is a non-symmetry depression basin,of which the proVenance is from the north. There are 13 third seCuences and 3 seCuence beds,which are t he results of 3 cycles. The large lake transgression is the middle upper of Yangxia For mation,which is consistent to the hot climate. The enVironment is the braided riVer,meandering riVer- delta,and delta and shallowlake,with the ephemeral sea transgression. The source rock is well distributed in the ephemeral sea transgression and the large lake transgression in the middle Jurassic. the reservoir distribution is the key factor to forming oil and gas accumulation.the river reservoir heterogeneity is controlled by the terrestrial environment,although t here are the Well distri bution of the sandbody and great reservoir thickness.
