| 摘 要： | 重力流成因的岩性油气藏是油气藏的重要类型之一。乌里雅斯太南洼槽下白垩统的重力流沉积砂体是盆地主要的储集体类型，但其分布复杂，沉积类型多样，内部的非均质性极强，对勘探和开发带来了很大的难度。通过精细的岩心观察，结合测井、3D地震，以及岩石分析资料等，笔者总结了盆地内的重力流沉积类型，分析了其平面的相分布特征，建立了盆地重力流沉积相模式，为研究区岩性油气藏的进一步勘探开发提供了依据。

| Abstract: | The lithologic pools produced by gravity flows are considered as one of the important types in petroleum exploration.The Lower Cretaceous sandstones as the main reservoir sandstones of gravity flow origin in the southern sag of the Uliastai depression are characterized by random distribution,various sediment types and highly inhomogeneity.The present paper deals with the type and planar distribution of the gravity flow deposits,and presents a sedimentary facies model for the Lower Cretaceous gravity flow de... |
