摘要: 基于高密度井网条件下数据资源和井距优势,对大庆长垣北部某沉积单元曲流河点坝砂体构型表征、剩余油分析和流体运移机理开展研究。针对点坝构型要素量化识别多解性问题,根据曲流河单砂体内部形态差异性对计算结果进行参数校正,实现构型要素确定性量化表征。同时,提出用构造进行砂体形态表征的建模思想,通过定向网格编辑技术,实现点坝砂体内部构型的三维表征。最后,利用数值模拟技术进行剩余油预测,明确构型影响下顺逆侧积注入的流体运移机理,提出下步挖潜方向。

Abstract: Based on the abundant data resources and the advantage of inter-well distance under the condition of high density well pattern, the characterization of the sand body architecture, remaining oil analysis and fluid migration mechanism of a meandering river point dam in a sedimentary unit in a block in Changyuan Daqing were studied. Aiming at the problem of multi-solutions of quantitative identification of point dam architecture elements, the parameter correction of the calculated results was carried out through the internal morphological difference of the meandering river single sand body, so as to realize the deterministic quantitative characterization of configuration elements. At the same time, the modeling idea of using structure to represent the shape of sand body is proposed, and the 3D characterization of point bar sand body internal configuration is realized by directional grid editing technology. Finally, through the numerical simulation technology to analyze the distribution of remaining oil and fluid migration, to clarify the mechanism of fluid migration under the influence of configuration, and put forward the next direction of tapping potential.

Key words: meandering river point dam, 3D characterization of architecture, parameter correction, the directional grid editing technology, fluid migration mechanism
