摘要： 针对鱼骨状分支水平井对应的典型注采井网,提出按照微单元的思想进行划分,采用数值模拟方法分析注采微单元的注采关系,流动特征,优化了注采微单元的注采对应关系,在此基础上针对斜向微单元开展了注采偏角、分支长度,分支位置的敏感性研究。根据优化结果提出对应的调整策略,预测结果显示这种调整策略可以有效地改善鱼骨状分支水平井注采井网的注水开发效果。

Abstract: This paper presents the micro well group conception to describe the typical injection-production well patterns for herringbone branch horizontal well. The analysis of the injection-production relation, flow behavior of the micro well group is made and its injectionproduction relation is optimized using numerical simulation method. Based on these, the sensitivity of angle of injection-production well, branch length and branch location of the herringbone well is studied. The adjusting strategies are proposed, and the result shows that the efficiency of the new well pattern is effectively improved.

Key words: branch well, horizontal well, well pattern, numerical simulation, injection-production well relation
