Khoom Qhia
Cov khoom lag luam kuj tsis ruaj khov thiab muaj zog, ua los ntawm cov hlau, thiab pab kaw ntsia hlau kom raug yog tias tsis muaj kev ua rau kev ua kom lub hau ntswj lossis lub sijhawm zoo heev. Ntxiv rau qhov tau plated rau lub sijhawm ntev divility thiab kev ua haujlwm, lub taub hau ntswj tau muab tso pov tseg nrog kev txhim kho corrosion thiab kom lawv zoo li tshiab.
Nrog kev cuam tshuam laum, tho xwm fab xwm yog tiv thaiv los ntawm kev tawg los ntawm ib qho chaw sib tw. Nws yog tsim los ua kev sib nqus heev kom tiv thaiv cov screws los ntawm kev poob tawm lossis swb nrog lub rauj laum tshiab. Qhov chaw torsional tiv thaiv lub siab siab thiab tiv thaiv lawv los ntawm kev rhuav thaum uas tsav los ntawm rab rauj laum. Los ntawm kev txhim kho lub laum me ntsis, cam debonding yuav tsum tau txo qis, nce kev nqus kev ua haujlwm thiab qhov raug, raws li kev txhim kho drilling efficiency.
Rau qhov kev tiv thaiv kom tsim nyog ntawm koj cov cuab yeej thaum lub sijhawm thauj mus los, yog lub thawv loj tuaj yeem siv tau. Tsis tas li ntawd, cov txheej txheem los nrog lub thawv cia yooj yim uas ua rau nws tau yooj yim dua los nrhiav cov khoom siv tsim nyog. Yuav kom ntseeg tau tias txhua tus tivthaiv tsis txav mus thaum xa khoom, nws yog muab tso rau qhov chaw muaj tseeb thaum lub sijhawm ua zaub mov xa tuaj.
