Nigute abakora imyitozo idafite magnetiki bakora?

1. Imikorere ya drill collar itari magnetique

Kubera ko ibikoresho byose bipima magnetiki byumva umurima wa geomagnetiki yumuriba mugihe upima icyerekezo cyuriba, igikoresho cyo gupima kigomba kuba mubidukikije bidafite magneti. Nyamara, mugihe cyo gucukura, ibikoresho byo gucukura akenshi usanga ari magnetique kandi bifite umurima wa magneti, bigira ingaruka kubikoresho byo gupima magnetiki kandi ntibishobora kubona amakuru yukuri yo gupima inzira nziza. Gukoresha amakariso adafite magnetiki arashobora gutanga ibidukikije bitari magnetique kandi bikagira ibiranga abakora imyitozo mugucukura. .

Ihame ryakazi ryimyitozo idafite magnetiki irerekanwa mumashusho. Kubera ko intera ya magnetiki yumurongo uri hejuru no munsi ya cola ya drill nta ngaruka igira kubikoresho byo gupima, ibidukikije bidafite magnetiki bishyirwaho kubikoresho byo gupima magnetiki, byemeza ko amakuru yapimwe nigikoresho cyo gupima magneti ari ukuri. amakuru ya geomagnetic.

2. Ibikoresho bitagira magnetiki ibikoresho bya cola ibikoresho

Ibikoresho bya magnetiki bitagira magnetiki birimo Monel alloy, ibyuma bya chromium-nikel, ibyuma bya austenitike bishingiye kuri chromium na manganese, ibishishwa bikozwe mu muringa, ibyuma bya SMFI bidafite magnetiki, ibyuma bya manganese-chromium-nikel, n'ibindi.

Landrill itanga amakariso yimyitozo isanzwe kandi izunguruka kuva 3-1 / 8''OD kugeza 14''OD ukurikije API, NS-1 cyangwa DS-1.
