Lub dab tshos laum uas tsis yog-Mag uas muaj kauv
Lub Qhov Caj Npab Uas Tsis Yog Mag Spiral yog tsim los kom muaj thaj chaw ntws ntau dua rau cov kua dej drilling, thaum muab cov txiaj ntsig ntawm cov hlau tsis yog mag rau cov kev pab cuam drilling nyuaj.
Lub Qhov Caj Dab Uas Tsis Yog Mag Flex
Lub Qhov Caj Npab Flex Non-Mag Drill Collar nyias dua thiab yoog tau dua li lub qhov caj npab drill collar. Lawv lub peev xwm tig tau luv luv, khoov rau lub kaum sab xis siab, thiab hla dhau cov ceg loj ua rau lawv zoo tagnrho rau kev siv rau kev taw qhia thiab kab rov tav. Ua los ntawm cov hlau tsis yog hlau, lub qhov caj npab drill collar no zoo heev rau kev siv rau cov khoom siv MWD.

Tsis yog Magnetic Stabilizer
Cov khoom siv ruaj khov uas tsis yog hlau nplaum yog ua los ntawm ib qho khoom khov kho uas tsis yog hlau nplaum. Cov khoom siv yog cov hlau tsis muaj hlau nplaum Chromium Manganese Austenitic uas muaj purity siab.
Kev tshuaj xyuas ultrasonic thiab kev tshuaj xyuas MPI raug ua tiav rau txhua qhov forging hla nws qhov ntev thiab ntu, tom qab kev ua haujlwm ntxhib raws li API Spec 71. Daim ntawv pov thawj xeem zeb suav nrog cov khoom siv kho tshuab, kev tshuaj xyuas tshuaj lom neeg, cov khoom sib nqus thiab kev tshuaj xyuas tau muab nrog txhua lub stabilizers.
Peb muaj peev xwm tsim cov Non Magnetic Stabilizer txog li Crown OD 26 ''
