Ko makora ekuboorera asingashandise magineti anoshanda sei?

1. Basa rekora yekuboorera isiri yemagineti

Sezvo zvese zvishandiso zvekuyera magnetic zvichinzwa geomagnetic field ye wellbor pakuyera kwakananga wellbor, mudziyo wekuyera unofanirwa kunge uri munzvimbo isina magnetic. Zvisinei, panguva yekuboora, zvishandiso zvekuboora zvinowanzova nemagnetic uye zvine magnetic field, iyo inokanganisa magnetic measurement zvishandiso uye haigone kuwana ruzivo rwakarurama rwe wellbore trajectory measurement. Kushandiswa kwe drill collars dzisina magnetic kunogona kupa nzvimbo isina magnetic uye kuve nehunhu hwe drill collars mukuboora. .

Nheyo yekushanda kwekora yekudhirowa isina magineti inoratidzwa mumufananidzo. Sezvo mitsetse yesimba remagineti iri pamusoro nepasi pekora yekudhirowa isina simba pamudziyo wekuyera, nzvimbo isina magineti inogadzirwa yemudziyo wekuyera ine magineti, ichiva nechokwadi chekuti data rakayerwa nechishandiso chekuyera chine magineti nderechokwadi.

2. Zvinhu zvekushandisa pakola yedhirivhari zvisiri zvemagineti

Zvinhu zvisina magineti zvekuboorera simbi zvinosanganisira Monel alloy, chromium-nickel steel, austenitic steel yakavakirwa pachromium nemanganese, copper-plated alloy, SMFI non-magnetic steel, domestic manganese-chromium-nickel steel, nezvimwewo.

Landrill inopa mabhora ekuboorera ari muchimiro chakajairwa uye akatenderera kubva pa3-1/8''OD kusvika 14''OD zvichienderana nezvinodiwa neAPI, NS-1 kana DS-1.
