Tataiso ea Tšebeliso le Tlhokomelo ea Lisebelisoa tse Matla tsa Magnetic tsa Drill String ke efe?

I. Litaelo tsa Tšebeliso 

1. Tlhahlobo ea Pele ho Ts'ebetso

- Netefatsa horemakenetebokaholimo ha bo na mapetso, mafome, kapa tšilafalo ea oli.

- Hlahloba dikgokelo tse nang le dithapo bakeng sa botsitso ho thibela ho arohana ha lesoba le ka tlase.

- Netefatsa matla a makenete (mohlala, ho sebedisa Gauss meter) ho netefatsa hore e fihlela ditlhoko tsa tshebetso.

2. Ts'ebetso ea ho theola lesoba

- Fokotsa khoele ea ho phunya butle-butle ho ea botebong ba sepheo, u qobe ho thulana ka tšohanyetso le seliba kapa tlhapi.

- Ha o atamela masalla a tšepe, potoloha khoele ea ho phunya ka RPM e tlase (≤30) ho ntlafatsa khoheli ea makenete.

- Lata khoele hantle ka mora ho monyela ho thibela ho lahlehelwa ke ditshila tse hapilweng.

3. Maemo a Sebetsang

- Haholo-holo e sebediswa bakeng sa ho lata thepa ya ferromagnetic (mohlala, dikotwana tsa di-bit, di-casing chips). Ha e a lokela ditshipi tse seng tsa makenete (mohlala, koporo, aluminium).

- E kgothaletswa bakeng sa didiba tse otlolohileng kapa tse nang le khutlo e tlase; didibeng tse nang le khutlo e phahameng, e sebediswe ka centralizer.

II. Tataiso ea Tlhokomelo le Tlhokomelo

1. Ho hlwekisa

- Hloekisa bokaholimo ba makenete hang ka mora ho bo sebedisa ka disele kapa sehlahiswa se ikgethang ho tlosa ditshila tsa tshepe le seretse se tjhekilweng.

- Qoba ho hohla makenete ka disebediswa tse bohale ho thibela ho senyeha ha makenete.

2. Thibelo ea ho Fokotsa Matla a Khoheli

- Boloka hole le matla a makenete a matla (mohlala, dienjene, mechini ya ho tjheseletsa).

- Arola limakenete tse ngata ka li-spacer tse seng tsa makenete (mohlala, liboloko tsa lehong) ho qoba ho thulana.

3. Tlhahlobo ea Kamehla

- Lekanya phallo ea makenete likhoeli tse ling le tse ling tse 3; kgutlisa bakeng sa ho tjhaja hape haeba matla a theoha ka >15%.

- Hlahloba masale a ho kwala hore na a senyehe (ho thibela ho kena ha mokelikeli le ho bola).

4. Litlhoko tsa Polokelo

- Boloka sebakeng se omileng (mongobo ≤60%, mocheso -20°C ho isa ho 50°C).

- Tlotsa mafura a thibelang mafome ebe o a phuthela ka pampiri e sa keneleng mongobo bakeng sa polokelo ea nako e telele.

III. Ho rarolla mathata 

- Adsorption e Fokolang: Hloekisa makenete kapa o tjhaje hape haeba e se e sebedisitsoe.

- Tšenyo ea khoele: U se ke ua qobella likhokahano; lokisa kapa u nke likarolo tse senyehileng sebaka.

- Ho Hlōleha ha ho Tšoasa Litlhapi: Netefatsa hore na tlhapi e na le ferromagnetic; fetohela ho lisebelisoa tse ling (mohlala, libaskete tsa lithōle) haeba ho hlokahala.

Bakeng sa diparamente tse itseng tsa tshebetso (mohlala, bokgoni ba mojaro, meedi ya mocheso ka mohlala), fana ka mohlala wa sesebediswa kapa maemo a sediba bakeng sa tataiso e eketsehileng.
