| 摘 要： | 随着国内外各类储层构型研究的深入,储层构型理论趋于成熟,但对于研究成果的运用一直很薄弱。在典型辫状河储集层构型研究的基础上,以A油田辫状河储集层为例,将辫状河储集层划分成辫状河道、心滩坝、落淤层、坝上沟道等构型要素,分析总结了辫状河储集层渗流屏障与连通体的确定原则与方法,以期直观指导油气田开发。研究表明,渗流屏障与连通体的识别,能将油藏开发前期静态构型模型与油藏开发后的动态流动单元类型联系起来,不同级别的渗漏屏障限制不同类型的流动单元,渗流屏障的发育直接影响周围流动单元的类型,从而影响油藏流体运动规律。

| Abstract: | With more in-depth investigations on various reservoir architectures, the theories of reservoir architectures have become increasingly mature, but application of the research results remains lagging. In this study, based on existing research on the architecture of typical braided stream reservoirs, a braided stream reservoir in the A Oilfield is divided into various architectural elements, such as the braided channels, mid-channel bars, silt layers, and troughs on bars. Criteria and methods for recognizing the seepage barriers and the connected bodies of braided stream reservoirs are analyzed and summarized, in order to provide intuitive guidance for oil and gas field exploration. The results reveal that the recognition of seepage barriers and the connected bodies establishes a linkage between the static architectural model at the pre-exploration stage and the dynamic classification of flow units at the exploration stage of oil reservoirs. Different classes of seepage barriers constrain different types of flow units. The development of seepage barriers directly impacts the types of the surrounding flow units and, thereby, affects the fluid movement pattern in the oil reservoir. |
