针对桩西采油厂油藏层系多,出水层位认识不清、层间干扰严重,部分含油层系得不到有效动用的问题,实施了不动管柱换层采油工艺。通过油管加液压实现封隔器坐封、丢手;换层时,不动管柱,套管加液压,推动液压换层开关活塞运动来变换长短轨道... 针对桩西采油厂油藏层系多,出水层位认识不清、层间干扰严重,部分含油层系得不到有效动用的问题,实施了不动管柱换层采油工艺。通过油管加液压实现封隔器坐封、丢手;换层时,不动管柱,套管加液压,推动液压换层开关活塞运动来变换长短轨道,实现换层。不动管柱换层采油工艺实现一趟管柱换层生产,减少常规管柱需上作业找水换层等繁琐的工作量,既降低作业成本,又提高了采油时率,取得了较好的增油效果。 展开更多

Referring to research on the Heterogeneous Network (Het-Net) application scenario and technique characters in IMT-Advaneed (The 4th Generation Mobile Communications) cellular system, this paper provides further analysis on main technique aspects of Heterogeneous Network, discussion on interference issue due to multi-layer building by access points and their corresponding solutions from standardization and engineering implementation. The proposed solution can effectively solve the interference problem in IMT-advanced Het-Net, and also improves the networking performance dramaticaUy for future mobile communication systems. 展开更多
