Kuiswa uye Kuverengera kweIADC Tricone Bits

Iye IADCchidimbu chetricone drill Classification uye manhamba system yakakosha pakuona nekunzwisisa maficha emhando dzakasiyana dzezviboorero zvinoshandiswa mukatimafuta, gasi, uye mvura kuchera matsime. Iyo system inoshanda sezvinotevera:

IADC inotsanangura kuti mhando yega yega yetatu trione zvishomainokamurwa uye inoverengerwa pachishandiswa kodhi ine manhamba, iyo inoratidza dhizaini yebhiti uye mashandisirwo aro mumhando dzakasiyana. Zvinorehwa nedijiti imwe neimwe ndezvizvi:

First Digit: Series Code

Iyi nhamba, inomiririrwa nenhamba 1-8, inoratidza maitiro emazino uye maumbirwo ayo bhiti rakakodzera. Kune marudzi maviri makuru emazino anoshandiswa mukatimafuta ekuchera tsime: mazino akakuya uye kuisa mazino (anowanzo kunziTCI drill bits kanaTungsten Carbide Insert (TCI) trione bits).

1. Mazino akagayiwa: Inokodzera kuumbwa kwakapfava ane yakaderera compressive simba uye yakakwirira drillability. Izvi zvinowanzoitika kunemilled zino trione bits.
2. Mazino akagayiwa: Inokodzera zvepakati kusvika pakati-yakaoma maumbirwo ane yakakwirira compressive simba.
3. Mazino akagayiwa: Yakakodzera kuumbwa kwakaomarara nepakati kusvika pakakwirira kukwenya.
4. Pinza mazino: Inokodzera zvinyoro zvinyoro zvine simba rakaderera rekumanikidza uye kudhiraivha kwakanyanya.
5. Pinza mazino: Yakanakira kune yakapfava kusvika pakati-yakaoma maumbirwo ane yakaderera compression simba.
6. Insert mazino: Yakagadzirirwa epakati-akaoma maumbirwo ane yakakwirira compressive simba, anowanzo shandiswa mukatiTCI trione bits.
7. Pinza mazino: Yakakwana kune yakaoma maumbirwo ane epakati abrasiveness kana abrasive maitiro.
8. Insert mazino: Inokodzera mafomu akaomarara ane yakanyanya abrasiveness, anowanzo shandiswa mukatitungsten carbide tricone drill bits.

Chechipiri Digit: Lithology Grade Code

Inomiririrwa nenhamba 1-4, nhamba iyi inowedzera kupatsanura maumbirwo ari muchikamu chekutanga chedhijiti kubva pakapfava kusvika kune yakaoma, ichiratidza izvo chaizvo zvinodiwa pakucheratrione rock bit.

Chechitatu Digit: Bit Structure Feature Code

Iyi manhamba, inomiririrwa nenhamba 1-9, inoratidza kutakura uye geji yekudzivirira maficha. Nhamba 1-7 dzinoshandiswa kutsanangura zvinonyanya kutakurwa uye kudzivirira masisitimu mumabheti emafuta, gasi, uye matsime emvura, nepo 8 ne9 zvakachengeterwa hunyanzvi hwemangwana.

1. Non-sealed roller bearings
2. Air-cooled roller bearings
3. Roller mabhengi ane geji kudzivirira
4. Yakavharwa roller bearings
5. Yakavharwa roller mabhengi ane gauge kudzivirira
6. Mabhengi anotsvedza akavharwa
7. Yakavharwa inotsvedza mabhengi ane geji kudzivirira

Yechina Digit: Yekuwedzera Structural Feature Code

Tsamba iyi kodhi inoshandiswa kumiririra zvimwe zvimiro zvisingagone kuratidzwa nenhamba nhatu dzekutanga. IADC yakatsanangura maficha gumi nematanhatu, senge kutonhora kwemhepo, mota application, uye akakosha ekuisa maumbirwo, angave akakosha kune zvimwe.zvidimbu zvitatu zvekoni. Mienzaniso yemamwe maficha anosanganisira:

- A: Kutonhora kwemhepo

- B: Special akavharidzirwa mabheji

- C: Pakati nozzles

- D: Directional kuchera

- E: Manozzles akawedzerwa

- G: Yekuwedzera geji yekudzivirira uye bit kuchengetedzwa kwemuviri

- H: Yakatwasuka uye yakananga mashandisirwo

- J: Nozzle offset

- L: Back-up stabilizers

- M: Motor application

- S: Mazino akagayiwa

- T: Twin cone

- W: Yakasimbiswa yekucheka chimiro

- X: Wedge-shaped inoisa

- Y: Conical inoisa

- Z: Mamwe maumbirwo ekuisa

Muzviitiko apo atrione rotary drill bitine akawanda ekuwedzera maumbirwo ezvimiro, iyo inonyanya kuzivikanwa inosarudzwa kuti inomiririrwa netsamba kodhi. Aya macode anobatsira kuziva chokwadidrill bit yekuongorora mafuta negasiuye chengetedza kutitrione zvishomainonyatsokodzera kune chaiwo mamiriro ekuchera uye maumbirwo akasangana.

Kunzwisisa iyi IADC classification system kwakakosha pakusarudza pakatiIsa Zino Drill Bits(TCI bits) uyeMilled Zino Tricone Bitskumapurojekiti akasiyana ekuchera matsime, angave ematsime emafuta, magasi, kana mabasa ekuchera matsime emvura.
