Drill Pipe Profile

Cov yeeb nkab steel nrog threaded kawg yog siv los txuas cov khoom siv saum npoo ntawm cov khoom siv drilling mus rau cov khoom siv drilling thiab sib tsoo lossis cov khoom siv hauv qab hauv qab ntawm qhov drilling rig. Lub hom phiaj ntawm cov yeeb nkab laum yog thauj cov av nkos mus rau qhov me me thiab nce, qis dua, los yog tig lub qhov hauv qab lub cuab yeej nrog lub ntsis. Lub laum yeeb nkab yuav tsum muaj peev xwm tiv taus qhov siab ntawm sab hauv thiab sab nraud, distortion, khoov thiab vibration. Nyob rau hauv cov txheej txheem ntawm cov roj thiab roj extraction thiab refining, laum yeeb nkab yuav siv tau ntau zaus. Laum yeeb nkab tau muab faib ua peb pawg: kelly yeeb nkab, laum yeeb nkab thiab qhov hnyav laum yeeb nkab. Kev sib txuas ua ke yog kelly yeeb nkab (1 thooj) + laum yeeb nkab (n daim, txiav txim siab los ntawm qhov tob tob) + hnyav laum yeeb nkab (n daim, txiav txim siab los ntawm kev sib dhos tsim). Kev faib tawm ntawm cov yeeb nkab laum, sib koom ua ke ntawm cov yeeb nkab laum, cov ntsiab lus ntawm cov yeeb nkab laum, qib steel thiab lub zog ntawm cov yeeb nkab laum yog qhia kom ntxaws.
