| 摘 要： | 鄂尔多斯盆地油藏属低渗透油藏,在长6特低渗致密岩性油藏中,注水开发时的孔隙结构和裂缝方向直接影响水驱油效果及注水开发的最终采收率。研究表明,拉长主裂缝方向上注水井到采油井的距离,缩短非主裂缝方向注水井到采油井的距离,可以提高注水开发效果,反九点菱形井网比反九点正方形井网最终采收率可提高3个百分点。

| 关 键 词： | 鄂尔多斯 裂缝方向 油水井距离 最终采收率 |

| Abstract: | Ordos Basin oil is a low permeability reservoir,especially during the long 6 Tight lithologic reservoir,the water injection when the direction of fracture pore structure and the direct impact of water flooding effects and water injection development in the ultimate recovery.The results showed that the direction of lengthening the main crack injection wells to production wells in the distance,the direction of reducing non-injection wells to the main crack distance wells may enhance the effects of water injec... |
