鉆柱轉矩 的英文怎麼說
中文拼音 [zhēnzhùzhuǎnjǔ]
鉆柱轉矩
英文
drill string torque-
The result of simulation of model 8 ? 1 / 2 ? xhp2s bit shows that, the torque on the bit changes randomly, and the degree of the change increases with the increase of the weight on bit ; the change of the torque on the upper part of the drillstring is not so large as that on the string ' s lower part, and the rotary speed of the bit changes smoothly overall
對8英寸xhp2s鉆頭做了模擬，結果表明，鉆頭處受巖石的阻力扭矩是隨機變化的，並有負扭矩出現，扭矩的變化幅值隨靜鉆壓的增加而增加；鉆柱頂部轉盤施加的扭矩變化不如底部劇烈；鉆頭的轉速在局部有較小的波動，其總體變化較為平緩。Torque feedback to suppress drillstring torsional vibration in extended reach well
大位移井鉆柱扭轉振動頂部扭矩負反饋減振研究By means of the simulation calculation, varying of the torques on the bit and the drillstring top and the rotary speed of the bit can be predicted
通過模擬計算可預測鉆頭處阻力扭矩、鉆柱頂部扭矩和鉆頭轉速的變化情況。
