EquiFlow™ Inflow Control Device (ICD) 均衡流入控制设备 Outline 提纲 • Technology Justification技术定位: Why Halliburton EquiFlow inflow control device为什么使用哈里伯顿 流入控制设备? • Design of EquiFlow ICD流入控制设备设计: Tube- Type ICD导流管类型的ICD • Modeling and Simulation 建模和模拟 • Case Histories 实例 • Zonal Isolation分层隔离: Easywell Swellable Technology 膨胀封隔器技术 • Conclusion 结论 Why Halliburton EquiFlow inflow control device? • Balance inflow to delay onset of water or gas breakthrough in OH horizontal wells 均衡流入，延 缓水平裸眼井气水突进 • Reduce ‘heel-to-toe’ effect 减少长裸眼段生产不均 匀的影响 • Prolong well life 延长井的生产寿命 • Increase recovery efficiency 提高采收率 – More oil, less water over time 多产油，少出水 – Less oil left in the ground 增加油藏开发程度 Application: Homogeneous Reservoir均质油藏 Application: Homogeneous Reservoir均质油藏 Application: Homogeneous Reservoir均质油藏 Example: reducing heel-toe effect, North Sea 减少根部－端部影响 ave k = 6D Heel-Toe Effect: WWS – 30% max flux variation ICD – 14% max flux variation Drawdown (Pres – Pann) @ 4,000 bopd: WWS – 30-39 psi (30% variation) ICD – 32-36 psi (14% variation) Application: Heterogeneous Reservoir非均质油藏 Application: Heterogeneous Reservoir非均质油藏 Application: Heterogeneous Reservoir非均质油藏 Application: Injection注水 EquiFlow™ Inject System • Balance injected fluid along the wellbore均衡注 水 • Reduce uneven flood- front distribution减少注水 前缘分布的非均匀 • Delay breakthrough and reduce injected water into producers延缓水突 进和减少产水 • Steam injectors注蒸气 e.g. SAGD Types of EquiFlow™ ICD Assembly类型 Sandstone Formation:
