eXtreme 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 usually 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” relative 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 Torsional Strength- 94,300 ft-lb接头扭矩强度 TJ Working Torque- 59,000 ft-lb接头工作扭矩 Pipe Body Performance Ratings:管体性能评估 New新 Premium一级 Torsion-ft-lb 105,500 83,000 扭矩 Tension-lb 844,200 666,500 抗张力 Int.
