1、,5-7/8 eXtreme Reach (XR) Drill Pipe5-7/8”极延伸钻杆,eXtreme Reach Drill Pipe initially developed to overcome hydraulic limitations encountered in ERD.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 TVDs of 20,000 ft and deeper are becoming more common 20,000

2、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套管，较长的 9-5/8” 或甚至更大口径的套管,eXtreme Reach Drill Pipe for Deepwater Applications 为深水钻井设计,eXtreme

3、Reach Drill Pipe for ERD大位移井用X级延伸钻杆的设计-1,Torque and Drag are generally considered to be critical drilling parameters for ERD Wells扭矩,牵引阻力常被以为是大位移钻井瓶颈 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 us

4、ually more restrictive. 如何降低液压流失是更大的约束,eXtreme Reach Drill Pipe for ERD大位移井用X级延伸钻杆的设计-2,Substantial ERD Projects Use 5-1/2” & 6-5/8” Drill Pipe许多此类钻井都以两套钻杆操作 5-1/2” DP introduces hydraulic limitations in long 12-1/4” hole sections. 5-1/2”钻杆在颇长的12-1/4”眼段中，液压效果不佳 6-5/8” DP represents an “overdesign” r

5、elative to drilling loads采用6-5/8”又大材小用 6-5/8” DP requires too much rig space and limits setback capacity占空间，立根数量减少 6-5/8” DP cannot be used to drill 8-1/2” hole sections 常规6-5/8”钻杆不宜钻8-1/2”井眼,5-7/8” 23.40# (0.361” wall) S-135 IU内镦粗5-7/8”(9.169mm壁厚)S-135钻杆,XT57 7.000” OD x 4.250” ID接头外内径尺寸 TJ Torsion

7、 XR Drill Pipe Hydraulic Benefits,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 Elevator

8、s 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 Pridecos 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

9、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 W

10、iper No modifications are required.钻杆刮泥器无须改动,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 Note:

11、If it becomes necessary to hang off and shear the pipe with the rams, a fixed ram for 5-7/8 may be required. Check with the B.O.P. manufacturer. 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

12、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,5-7/8 XR Drill Pipe Handling Equipment Changes采用5-7/8”钻杆所需改动的配套

13、工具器材,Pick-up Line No modifications are required.吊绳无需改动 Crossover Subs Crossover subs need to be ordered with the XT57 tool joint.变换短节需有XT57接头 Lift Nipples No modifications are required.提升短节无需改动 Top Drive Bell Stabbing Guide The top drive bell stabbing guide should be checked to ensure a tight cleara

14、nce between the stabbing guide and the box connection. Adjust the effective bore in the top drive bell stabbing guide to ensure there is no more than clearance (on the diameter) between it and the XT57 box tool joint OD. With a 7.000 O.D. tool joint, the standard 5” top drive bell stabbing guide wil

15、l usually work good. (Varco flipper part number is 99304).顶驱钟形对扣器或许需调整间隙（小于半寸） Rig Floor Stabbing Guide A stabbing guide should be used on the rig floor any time a pin is stabbed into the box. For the XT connection, this will ensure proper alignment when stabbing and reduce stabbing damage.一定要使用适当的对
