Drilling Bit Technology | Maitiro eKusarudza Dhidhiro Bhiti reZvinyoro Mafomati, Abrasive Formations, uye Nyore Kutsauka Mafomati?

Kunyanya, pakuchera mafuta kana mvura, zvinhu zvakasiyana zvinofanirwa kuverengerwa, senge lithology, nzvimbo yechikamu chetsime, uye chimiro chetsime. NekugadzirisaAPI yakajairwa trione bitsneiyo chaiyo maumbirwo uye mamiriro ekuchera, unogona kuvandudza kuchera uye kuderedza kusakara uye kubvaruka pairitungsten carbide kuisa bits.

Saka, tinofanira kusarudza sei zvakaruramaisa zino zvidimbu zvetriconekanamilled zino trione bitskukwenenzvera kuchera kuita uye mutengo-kubudirira?

1. Ndeapi Mhando dzeDrill Bits Ariko Kubva paBasa?

Drill bits inogona kuiswa mumhando dzakasiyana zvichienderana nebasa, kusanganisira:

• Full-diameter drill bitsyekuchera zvachose (semuenzaniso,matatu makoni anoboorera zvishoma)
• Annular drill bits(core barrel drill bit), sengeisa zvimedu zvekubooresa zino, iyo inoshandiswa kune chaiyo yakakosha yekudzosa zvinodiwa.

Kune maumbirwo akapfava,dhonza zvimedukanazvimedu zvemazino zvakagayiwainogona kunge iri sarudzo iri nani, nepo kune yakaoma uye yakawanda abrasive maumbirwo,tungsten carbide tricone drill bitszvakanaka.

2. Ndeapi Hunhu hweTricone Bits?

Tricone bits, sengecore barrel ine roller conesuyeTCI drill bits, vanozivikanwa nenzvimbo yavo diki yekusangana pakati pemazino uye kuumbwa, zvichitungamira kune yakakwira bit pressure, kuderedzwa kushanda torque, uye kureba blade kureba. Aya maficha anoita kuti ave akakodzera kune akaoma mafomu, kusanganisiramvura tsime trione bitsuyemafuta ekuchera tsime.

3. Mangani Mhando dzeTricone Bits Aripo?

• Nehuwandu hwemakoni:Kunesingle-cone,mbiri-cone,uyetri-cone bits.TCI trione bitsuyemilled zino trione bitszvakajairika kune akasiyana maapplication, kusanganisiramigodhi trione bitsuyegasi drill bits.
• Nechimiro: Kunebody-typeuyeisiri-yemuviri-mhandotrione bits, imwe neimwe yakagadzirirwa zvinangwa zvakasiyana.
• Nerudzi rwezino:Milled tooth bitsanowanzoshandiswa mumhando dzakapfava, nepoisa zvimedu zvekubooresa zinopamwetungsten carbide kuisazviri nani zvakakodzerwa nemaitiro akaomarara.

4. Ndezvipi Zvikamu zveTri-cone Bit? Ndeapi Mabasa Azvo?

Atungsten carbide tricone drill bitine zvikamu zvakati zvakakosha:

• Bit muviri nemaoko: Inobatanidza kune yekuchera chishandiso, ichipa tsigiro yeiyo bit.
• Cones: Inowanikwa mu single-cone, dual-cone, kana tri-coneTCI drill bitszvinonyanya kushanda mukuumbwa kweabrasive.
• Bearings: Ita shuwa kutenderera kwakatsetseka kwemakoni uye kutakura axial uye radial mitoro.Roller cone bitskazhinji shandisa mabhengi emhando yepamusoro kuti awedzere kusimba.
• Zviteshi zvemvura: Yakakosha pakutenderera kwemvura.Jetting bits(inowanikwa mumvura tsime trione bits) shandisa manozzles kunyatsonangisa mvura yekuchera kuchenera kucheka.
