摘要: 应用Miall建筑结构分析法研究胜坨油田沙二段34小层砂体内部建筑结构:根据取芯井岩芯观察识别出13种岩相类型;通过岩芯观察,连井剖面对比和测井曲线识别,采用层次分析的思路定义了6级界面;在岩相识别和界面划分的基础上划分出7种结构要素:河道滞留沉积(CHL)、河道充填(CH)、心滩(CB)、落淤层(FS)、天然堤(LV)、决口扇(CS)和越岸细粒沉积(OF);建立了34砂体建筑结构平面和剖面组合模式:平面以河道充填(CH)和心滩(CB)为主,剖面上可分为3个层次。

Abstract: Miall architectural structure analysis is applied to study the reservoir architecture structure of the subbed of Es234 of Shengtuo oil field. Thirteen types of lithofacies are distinguished through core observation. Based on the observation, correlation of connectingwell sections and recognizition of well logging curves, with the conception of stratification, six scales of bounding interfaces are defined. Based on the recognization of lithofacies and the classification of sequences, seven kinds of structures are identified, and they are channel sediments(CH), channel retention sediments(CHL), channel bar(CB), fallsiltseam(FS), natural levee(LV), crevassesplay (CS), Overbank fine sediments(OF). And finally, the planar and sectional assemblage models of architecture structure of 34 sand body are established. Channel filling(CH) and channel bar (CB)are the main architectural elements in the plane and three hierarchies are divided in the section.

Key words: architectural structure analysis, lithofacies, bounding interface, architectural element
