摘　　要：充分利用济阳坳陷东营凹陷北部胜坨油田二区取芯资料全、井网密的优势,按照叠置河口坝、单一河口坝以及前积体的顺序进行层次分析,对河口坝沉积规模进行了定量研究,提出了一套河口坝构型量化分析的方法。研究认为:本区河口坝构型可以分为5个级次,其中第3和第4级次是构型研究的重点;河口坝的长度与厚度及长度与宽度均呈双对数线性关系;前积体的产状,延伸范围及组合存在多解性,在进行分析时需参照河口坝构型模式以及岩芯分析、测井曲线对比和动态开发特征进行综合研究。With advantage of a great quantity of coring data and dense well pattern, this paper studies architecture of debouch bar according to order of superimposed debouch bar. Sedimentary scale of debouch bar is studied quantitatively. Ane writer proposed the quantitative analysis method of architecture of debouch bar. Writer suspected that there are 5 levels in architecture of debouch bar of this block. The 3rd and 4th level are the most important in the architecture studying. Length--thickness and length--width of debouch bar both are log--log type linearity. Attitude, expanded range and association of foreset body all obtain ambiguity. It is needed comprehensive research of pattern of architecture of debouch bar, core analysis, log comparison and developmental character when we analysis Attitude foreset, expanded range and association.
