IADC Tricone Bit Itondekanya Kode Sisitemu

IADC roller cone gucukura bitondekanya imbonerahamwe ikoreshwa kenshi muguhitamo ibyiza bito kubikorwa runaka. Iyi mbonerahamwe ikubiyemo bits ziboneka muri bane bayobora inganda za bits. Bits zashyizwe mubikorwa ukurikije ishyirahamwe mpuzamahanga ryabashinzwe gucukura (IADC). Umwanya wa buri biti mubishushanyo bisobanurwa nimibare itatu nimiterere imwe. Urukurikirane rwimibare isobanura "Urukurikirane, Ubwoko nibiranga" bya bit. Inyongera yinyongera isobanura ibiranga inyongera.

Kode ya IADC

Umubare wa mbere:

1, 2 and 3 designate Steel Tooth Bits, with 1 for soft, 2 for medium and 3 for hard formations.

4, 5, 6, 7 and 8 designate Tungsten Carbide Insert Bits for varying formation hardness with 4 being the softest and 8 the hardest.

Umubare wa kabiri:

1, 2, 3 and 4 help further breakdown the formation with1 being the softest and 4 the hardest.Umubare wa gatatu:

Iyi mibare izashyira mubice bito ukurikije ubwoko bwa kashe / kashe hamwe nuburinzi bwihariye bwo kwambara bikurikira:

1.Standard ifunguye ifite roller bit

2.Standard ifunguye biti yo gucukura ikirere gusa

3.Standard ifunguye biti hamwe no kurinda igipimo bisobanurwa nk

karbide yinjiza mumatako ya cone.

4.Urupapuro rufunze biti

5.Umuzingo ufunze biti hamwe na karbide winjizamo agatsinsino ka cone.

6.Ikinyamakuru gifunze biti biti

7.Ikinyamakuru gifunze biti hamwe na karbide yinjizamo agatsinsino ka cone.

Umubare wa kane / Ibaruwa yinyongera:

Inyuguti zikurikira zikurikira zikoreshwa mumwanya wa kane kugirango werekane ibintu byiyongereye:

A - Porogaramu yo mu kirere

B - Ikidodo kidasanzwe

C - Centre Jet

D - Kugenzura gutandukana

E - Indege zagutse

G - Kurinda igipimo cyihariye

H - Porogaramu itambitse

J - Gutandukana

L - Amashanyarazi

M - Gusaba moteri

R - Gusudira imbaraga

S - Amenyo asanzwe

T - Bits ebyiri

W - Kuzamura Imiterere yo Gutema

X - Shyiramo Chisel

Y - Shyiramo

Z - Ubundi buryo bwo gushiramo

Ijambo "koroshya" "urwego" na "rukomeye" ni ibyiciro byagutse cyane mubice bya geologiya byinjira. Muri rusange, ubwoko bwurutare muri buri cyiciro bushobora gusobanurwa gutya:

Imiterere yoroshye ni ibumba n'umucanga.

Ibi birashobora gucukurwa hamwe na WOB ugereranije (hagati y'ibiro 3000-5000 / muri diameter ya biti) na RPM ndende (125-250 RPM).

Igipimo kinini kigomba gukoreshwa mugusukura umwobo neza kuko ROP iteganijwe kuba hejuru.

Igipimo cyinshi cyinshi ariko gishobora gutera induru (reba imiyoboro ya drillage). Ibiciro bitemba 500-800 gpm birasabwa.

Nka hamwe na biti zose, uburambe bwaho bugira uruhare runini muguhitamo ibipimo bikora.

Hagati yo hagati irashobora gushiramo shale, gypsumu, lime ya shaley, umucanga na siltstone. 

Mubisanzwe WOB yo hasi irahagije (3000-6000 lb / muri diameter ya biti).

Umuvuduko mwinshi wo kuzenguruka urashobora gukoreshwa muri shale ariko chalk isaba umuvuduko muke (100-150 RPM).

Amabuye yoroshye yumucanga arashobora kandi gucukurwa muribi bipimo.

Ubundi umuvuduko mwinshi urasabwa gusukura umwobo

Imiterere ikomeye irashobora gushiramo hekeste, anhydrite, ibuye ryumucanga rifite imirongo ya quartic na dolomite.

Izi ni urutare rwimbaraga zo guhonyora kandi zirimo ibintu byangiza.

WOB ndende irashobora gukenerwa (urugero hagati y'ibiro 6000-10000 / muri biti ya diameter.

Muri rusange umuvuduko wo kuzenguruka buhoro ukoreshwa (40-100 RPM) kugirango ufashe gusya / guhonyora.

Ibice bikomeye cyane bya quartzite cyangwa chert nibyiza gucukurwa hamwe na bits cyangwa diyama ukoresheje RPM yo hejuru na WOB nkeya. Ibipimo bitemba muri rusange ntabwo ari ingenzi muri ubwo buryo.
