| 摘 要： | 特低渗透油藏的开发与裂缝(天然裂缝与人工裂缝)密切相关,因此井网部署是否合理是特低渗透油藏开发成败与否的关键。在分析特低渗透油藏地质特征的基础上,研究了特低渗透油藏开发中合理井网部署的关键问题,即裂缝方向与合理井排距的确定。在分析传统的特低渗透油藏开发中根据裂缝不发育、较发育和发育三种不同情况,采用正方形反九点、菱形反九点、矩形三种井网形式的井网优化技术的基础上,提出了充分考虑特低渗透油藏储层非均质性的不规则布井的矢量化井网,同时提出了与矢量化井网配套的压裂工艺,在特低渗透油藏的开发中取得了明显效果。 |

| Abstract: | The exploration of extra-low permeability oil reservoir closely connected with crack(nature crack &hydraulic crack),so whether the deployment of wells is reasonable or not is the key point to decide oil reservoir's success.Based on the analysis of extra-low permeability oil reservoir character,this article explains the key problems to properly arrange wells,namely how to confirm crack direction and appropriate wells' distance;it put forward an optimum technology for the deployment of wells.According to thre... |
