Revolutionizing Drilling: Advanced Bit Solutions.
Ukuhlanganiswa Nochungechunge Lomkhiqizo lwe-API Standard Tricone Bits
1. Izingxenye zeI-Tricone Rock Bits
Izingcezu ze-Tricone drill zakhiwe izingxenye ezinhlanu eziyinhloko: umzimba we-drill bit, umlenze, ama-cones, i-bearing, kanye ne-nozzle. Kuma-jet bits avaliwe, afaka nesistimu yokugcoba kanye nesinxephezelo.
2. Uchungechunge lwe-Tricone Drill Bits
① Uchungechunge Lobubanzi beI-Tricone Drill Bits
I-Domestic Drill Bits: Uchungechunge lobubanzi luhlanganisa osayizi abayi-15. Okuvame ukusetshenziswa yi-Kingdream 17 1/2", 12 1/4", 9 5/8",8 1/2", kanye no-3 7/8".
Izingcezu Zokubhola Ezingenisiwe: Ububanzi bobubanzi buyinkimbinkimbi kakhulu. Isibonelo, ama-drill bits asuka e-US-based Hughes Company amboza osayizi abangama-46 ukusuka ku-3 3/4" ukuya ku-26".
② Ukufakwa kwekhodi kwe-Kingdream Oil Tricone Bits
- Ikhodi yemodeli iqukethe izingxenye ezine:
- Ikhodi yeBit Diameter: Imelwe ngamayintshi, iphelele noma iyingxenye.
- Ikhodi Yochungechunge: Ibonisa izici eziyinhloko zesakhiwo sokuthwala nokuvala se-Three Cones Drill Bit, ehlukaniswe ngezigaba eziyisishiyagalolunye.
- Ikhodi Yokuhlukanisa: Amadijithi amathathu lapho:
- Idijithi yokuqala ibhekisela esakhiweni sokusika kanye nochungechunge lokubunjwa.
- Idijithi yesibili ikhombisa izinga lokubunjwa.
- Idijithi yesithathu isho izici zesakhiwo sebhithi.
- Izici Ezengeziwe Zesakhiwo: Ngezidingo ezikhethekile, ukuguqulwa kuqashelwa ngohlamvu olulodwa noma ngaphezulu okulandela ikhodi yokuhlukanisa.
Isibonelo:
- 8 1/2": Ububanzi bebhithi.
- I-HJT: I-sliding bearing enophawu lwensimbi nokuvikelwa kwegeji ekhethekile.
- 537: Amandla acindezelayo aphansi, ukwakheka okuthambile kuya kokuphakathi, i-TCI Tricone Bit.
- G: Umlenze oqinisiwe.
3. Ukukhethwa kwezingcezu ze-Tricone
Okukhethwa kukho kuncike kudatha evela kumafomu afanayo emithonjeni engomakhelwane, izimo zokubunjwa, nesimo esithile somthombo. Cabangela:
- Ubulukhuni bokwakheka kanye ne-abrasiveness.
- Ukujula kwesigaba esibhobhile.
- Ukwakheka okuthambekile okudinga ukubhola okulwa nokuchezuka.
- Ukushintshanisa ukwakheka okuqinile nokuthambile.
4. Ukwahlulela I-Tricone Bit Conditions Downhole
① Ukusebenza Okuvamile:
Nge-lithology yokwakheka engaguquki, ukunyakaza kwetafula elijikelezayo kufana, isivinini sokubhoboza sihlala sizinzile, futhi izinkomba ezilinganisweni zokucindezela azishintshi.
②Ukuhluleka kokuthwala:
Ukunyakaza kwe-periodic stick-slip kwethebula elijikelezayo, ukunciphisa isivinini sokubhola, nokufundwa okuguquguqukayo kwesisindo-on-bit.
③Ukukhiya Ikhoni:
Ukwenyuka komthwalo ojikelezayo, ukushelela kwenduku okunzima, nobunzima bokuzungezisa intambo yokubhoboza.
④Ikhoni Elahliwe:
Ukwenyuka okuphawulekayo komthwalo ojikelezayo, ukunyakaza okungazelelwe kokushelela kwezinti, nokuncipha kwezinga lokungena noma ukungaqhubeki kokumba.
⑤Amazinyo Agugile:
Umthwalo we-rotary olula, izinga lokungena elinciphile, nokufundwa kwegeji yokucindezela okuqinile.
⑥ I-Bit Balling:
Ukwenyuka komthwalo ojikelezayo, izinga lokungena elinciphile, nomfutho wephampu ophakeme.
Diamond kanyeI-PDC Hudula Izingcezu
1. Ukwakheka Kwezingcezu Zokubhola Idayimane
- Izingcezu Zokubhola Ledayimane Lemvelo: Akhiwe ngomzimba wensimbi, i-matrix, umlomo wombhobho, nezinhlayiya zedayimane.
- I-PDC Cutter Drill Bits: Bandakanya umzimba wensimbi, i-matrix, umlomo wombhobho, nabasiki bedayimane be-polycrystalline.
①Izimo Zephrofayela
Amabhithi okudonsa e-PDC anemimo emithathu:
- I-Parabolic: Ifanele ukwakheka okuthambile, okuhlinzeka ngesivinini esikhulu sokubhola nokuzinza.
- Indilinga:Ilungele izixhumi eziqinile ngenxa yama-hydraulic agxilile.
- I-Conical:Idizayinelwe ukungena okuqinile nokuzinza ekusebenzeni kwesivinini esikhulu.
②Ukukhetha okuncane
Cabangela izici ezifana nendlela yokubhoboza, uhlobo lokubunjwa, nemingcele yokubhoboza lapho ukhetha i-PDC Drag Bit.
③ Imihlahlandlela yokusetshenziswa efanele
- Gcina umfutho wepompo ungaphezu kuka-13 MPa.
- Gwema ukungqubuzana nezinto eziqinile kanye nemithelela engazelelwe ngesikhathi sokumba.
- Hlanza kahle iphansi lomthombo ngaphambi kokuqala ukusebenza.
- Sebenzisa amapharamitha wokubhola afaneleka kakhulu: isisindo-on-bit (30–60 KN), isivinini sokujikeleza (117–217 RPM).
3. Ama-Coring Drill Bits
Ama-Coring drill bits aklanyelwe ukuchotshozwa kwe-annular ukukhipha ama-rock cores. Izinhlobo ezijwayelekile zifaka izingcezu zokudonsa, izingcezu ze-tungsten carbide core, nama-diamond core bits. Izici ezifana ne-symmetry nokumelana nokugqoka ziqinisekisa amazinga aphezulu okutholwa okuyisisekelo.
