• Improve reservoir productivity by decreasing amount of over balanced 保护油气层不受破坏
• Improved wellbore quality by minimising wellbore collapse 减少井口崩溃
Managed Pressure Drilling Definition
• Manual choke with continuous control or automated choke system •手动节流，连续控制或自动节流系统 • Back pressure pump system for constant BHP 回压补偿泵，保持 井底压力不变
MPD Operations 控压作业
pore pressure)
• 主动控压（泥浆静液柱稍高于或有时低于地层压力） • MPD being used to ‘walk the line’ 使用MPD“压线走”
•E.g. naΒιβλιοθήκη Baidurow pore pressure to frac pressure window 如地层压力 和破裂压力之间的窗口很窄 • RCD with change out system like additional BOPs 增加旋转控制设 备
• “Adaptive drilling process used to precisely control the annular pressure profile throughout the wellbore. The objectives are to ascertain the downhole pressure environment limits and to manage the annular hydraulic pressure profile accordingly”. (IADC)
Managed Pressure Drilling Operations
Controlling pressure in the annulus 控制井口压力 • Not a new concept • Technique has been used for decades • When used while drilling with conventionally with
• Mud-cap drilling (with under or overbalanced fluid)
• 泥浆帽钻井（欠或过平衡）
• Usually use for fractured limestones or granites
• MPD used as a safety system 控压钻井作为一种安全体系
• Rotating Control Device (RCD) 旋转控制设备 • Manual Choke (Rig Choke for US land wells) 手动节流设备（用于 美国陆上井的节流设备）
• Active MPD (hydrostatic mud weight slightly above or sometimes below
Advantages of MPD 控压钻井技术应用效应
• Improved ROP and reduced drilling time 改善钻速和减少钻井时间
• Improved success with drilling narrow pressure margins 钻井狭窄压力窗口
• Reduced wellbore breathing, influxes and lost circulation 减少的井筒呼吸，成功应付井侵和失返

Well control event 井控情况下 • Control BHP by applying back-pressure at surface 通过
地面加回压控制井底压力 • Closed-loop (BOP is closed) 闭环（防喷器关闭) • Circulation is through a choke 通过节流阀循环
General Comparison of drilling methods 钻井方法对比
MPD Operations 控压作业
• Passive MPD (hydrostatic mud weight always above pore pressure)
• 被动控压钻井（泥浆静液柱压力总是高于地层压力）
