該廠的主要產品有:地質巖芯鉆機工程施工鉆機水文水井鉆機汽車鉆機鉆塔泥漿泵金剛石壓機人造金剛石及製品液動螺桿鉆泵井壁管和抽油桿以及一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。In chapter six, based on the preceding chapters " research, the practicality of the full scale dr i 11 ing simulating test device has been tested by the debugging and the performance test. under simulating drilling conditions, the rock mechanical properties and the bits " dynamical tests are analyzed and set forth specifically. at the same time the effect of bottom pressure difference on the oil field exploration and development has been discussed
第六章在前述分析研究的基礎上,通過對模擬裝置的系統調試及性能測試,驗證了全尺寸鉆井模擬裝置的實用性,在鉆井模擬條件下對巖石的機械性質、牙輪鉆頭動態測試給予了具體的分析闡述,同時還分析探討了井底壓差對油田勘探開發的影illb ,並且為宋深101井的實際施工作業提供了非常有價值的指導參數。
