Ko non-magnetic drill collars inoshanda sei?

1. Kushanda kwe-non-magnetic drill collar

Sezvo ese magineti ekuyeresa zviridzwa zvichinzwa geomagnetic munda wetsime kana uchiyera kutaridzika kwegomba, chiridzwa chekuyeresa chinofanira kunge chiri munzvimbo isiri magineti. Nekudaro, panguva yekuchera, maturusi ekuchera kazhinji ane magineti uye ane magineti, ayo anokanganisa magineti ekuyeresa zviridzwa uye haakwanise kuwana chaiyo wellbore trajectory yekuyera ruzivo. Kushandiswa kweasiri-magnetic drill makora anogona kupa isina-magineti nharaunda uye kuve nehunhu hwekudhirowa makora mukuchera. .

Nheyo yekushanda ye-non-magnetic drill collar inoratidzwa mumufananidzo. Sezvo kupindira kwemagineti mitsara pamusoro uye pazasi pechibooreso chekorori isina chekuita pachiyereso chiridzwa, nzvimbo isina magineti inogadzirwa kune iyo magineti yekuyeresa chiridzwa, kuve nechokwadi chekuti data yakayerwa negineti yekuyeresa chiridzwa ichokwadi. geomagnetic field information.

2. Non-magnetic drill collar zvinhu

Zvisiri-magnetic drill collar zvinhu zvinosanganisira Monel alloy, chromium-nickel simbi, austenitic simbi yakavakirwa pachromium uye manganese, copper-plated alloy, SMFI isiri-magnetic simbi, yepamba manganese-chromium-nickel simbi, nezvimwe.

Landrill inopa zvibooreso makora mune yakajairwa uye yakapetwa kubva pa3-1/8''OD kusvika 14''OD zvinoenderana neAPI, NS-1 kana DS-1 zvakatemwa.
