摘要

本文通过大量岩心观察

认为我国东部中-新生代几个含油气盆地浅水湖泊砂体是浅水洪水流的产物

系洪水岩。在对洪水岩的岩性、构造特征及层序描述、分析的基础上

区分出三种沉积微相:1.水道沉积微相

2.漫溢沉积微相

3.远端沉积微相。将以东濮盆地和松辽盆地为代表所提出的浅水充氧陆源碎屑湖泊砂体成因模式归纳为四个特点。

Abstract

It has been proved by observation of a lot of cores that shallow lacus-trine sandbodies in hydrocarbon-bearing basins of the Meso-Cenozoic inEast China are the products of flood flow and can be divided into three se-dimentary microfacies:1.Channel microfacies

characterized by multistoryfinger sandbodies with base scour and parallel-lamination;2.Overflow mi-crofacies appeared as sheet-like sandbodies with mixed character of coarseand fine grain;3.Distal microfacies

characterized by well-developed lamina-tion and common burrows.The genetic model of shallow lacustrine terrige-nous debris sandbodies

represented by the ones of the Dongpu and Shong-liao Basins

have four properties.
