ERD.最初是为克服深水兼大位移钻井时的液压流失问题 最初是为克服深水兼大位移钻井时的液压流失问题 • Interest for Deepwater also generated. 但仅深水也有能用及之处 • Deepwater wells with TVD’s of 20,000 ft and deeper are becoming more common 20,000尺或更深的深水井越来越普通 尺或更深的深水井越来越普通 • Deepwater has reduced margins between pore pressure and fracture gradient深水操作时,岩层空隙压力 深水操作时, 深水操作时 与裂压梯度间的可操作范围更窄. 与裂压梯度间的可操作范围更窄. • Require several casing points and long 9-5/8″ or larger protective casing strings.这种情况造成需要下多处 这种情况造成需要下多处 套管，较长的 9-5/8” 或甚至更大口径的套管 套管， 5/8”

5-7/8″ XR Drill Pipe Handling Equipment Changes采用5-7/8”钻杆所需改动的配套工具器材
B.O.P. Pipe Rams – If variable size rams are being utilized, no modifications are required. Otherwise, the B.O.P. pipe rams will have to be ordered for the 5-7/8″ drill pipe.防爆器的闸板需配套
Drill Pipe Safety Valve – The safety valve should be ordered to be used with the XT57 and a 4-1/4″ ID.钻杆安全阀的接头 Finger Board – No modifications are required.指杆台不需变动 Automatic Pipe Handling Equipment – No modifications required. 自动操管系统无需更动 Iron Roughneck Spinner – No modifications are required.转动抓管钳？ Mud Bucket – The mud bucket will need to be bored out so that it will seal around the pipe body.泥斗需要扩径

Slips – 5-1/2″ slip bodies can be used. Thinner dies will be required on the slips to accommodate the 5-7/8″ drill pipe. A 7″ slip body dressed with inserts to grip the 5-7/8″ pipe body can also be used. The 7″ slip body will allow the use of thicker dies.卡瓦片需调整厚薄 Elevators – New elevators with 6-1/8” bore should be used.吊卡孔眼 Top Drive Saver Sub – The top drive saver sub should be crossed over to Grant Prideco’s XT57 connection. All Varco top drive saver subs should be 5-1/2″ from shoulder to shoulder. This ensures the top drive pipe handler torque wrench grips the box at least 2″ from the box shoulder face, eliminating opportunities for squeezing the box in the counterbore region. As such, for other top drive brands, the top drive saver sub should also be a length which provides torque wrenching at the same 2″ length minimum from the box shoulder face.顶驱短节长度需调整 Pipe Wiper – No modifications are required.钻杆刮泥器无须改动
• Torque & Drag are significant constraints, but are generally not the governing drill pipe design issues.但从整个钻井效益，钻杆设计角度而言 • Hydraulic limitations are usually more restrictive. 如何降低液压流失是更大的约束
