摘要：

依据Miall河流相储层构型理论，综合应用储层地质学、开发地质学和油藏地球化学的基本原理和方法，对长庆马岭油田北三区延10¹储层构型进行了详细研究。根据Miall构型要素划分方案，将延10¹划分为河道、废弃河道、溢岸及洪泛平原细粒沉积4种构型要素，各构型要素间存在复杂的组合关系。具体表现为：多期河道侧向叠加，堤岸砂体位于砂体的边缘，两条河道之间由于侧向侵蚀作用而不发育溢岸沉积；多期河道侧向叠加，在两期河道之间残留堤岸砂体或泛滥平原沉积；两期河道之间堤岸砂体被冲刷剥蚀，大片砂体为河道沉积；河道砂体内发育废弃河道。同一地层单元内，可同时出现上述几种情况。

Abstract:

The architecture of Ty10 Reservoir in No.3 district of the northern Maling Oilfield was researched using the Miall theory combined with the principles of reservoir geology, development geology and reservoir geochemistry. In the light of the architectural theory, the Ty10 Reservoir can be divided into architectural elements of channel, abandoned channel,levee,floodplain fine, among which there are complex combinations. Namely, the multi-channel was laterally stacked with depositing lateral overbank and lacking overbank sands owing to eroding. The overbank sands were remained in the lateral over-bank and lacking over-bank. The channel sands were widely deposited in the stacked channels, and abandoned channel existed in the channel sands. The reservoir architectures above mentioned could occur simultaneously in the same formation at the same epoch.

Key words: fluvial reservoir architecture, Maling Oilfield, reservoir geochemistry, Miall architectural element, geology theory
