Izinhlobo Ze-Drill Bit

1. Izingcezu Zokubhoboza zeTricone:

Ama-rolling cutter bits (noma ama-rotary cone bits) anezakhi zawo zokusika ezihlelwe kuma-cones azungeza ama-axes awo njengoba umzimba we-bit ujikeleza. Inani lama-cones ku-bit lingaba yi-1, 2, 3, 4, 5, noma 6. Kodwa-ke, ama-rotary cone bits avame kakhulu ama-tri-cone bits. Cishe ama-95% emithombo kawoyela negesi emhlabeni wonke abholwa kusetshenziswa ama-rolling cutter bits, ikakhulukazi ama-tri-cone bits. Ezimweni ezithambile, amazinyo amade futhi aqhelelene kakhulu. Kumatshe aqinile, usayizi wamazinyo kanye nesikhala kuyancishiswa.

• Amabhithi Ekhoni Elilodwa: Lolu hlobo lwebhithi lujikeleza i-axis yalo futhi lusetshenziswa kakhulu ekubholeni okuqondiswe ohlangothini. Lawa mabhithi asetshenziswa ezinhlelweni zokubhoboza ezijikelezayo zezakhiwo eziqhekekile, izakhiwo ezihudulayo, izakhiwo eziqinile eziphakathi nendawo, kanye nezindawo ezine-engile. Amabhithi anekhoni elilodwa anciphisa amathuba okuphambuka komthombo.
• Amabhithi Amakhoni Amabili: Isetshenziswa kakhulu ekwakhekeni okuthambile kanye nokubhoboza okuqondisiwe.
• Amabhithi e-Tri-ConeAma-bits e-tri-cone ayizinhlobo ezivame kakhulu ze-bit, ezisetshenziswa emisebenzini eminingi yokubhoboza emhlabeni jikelele.

Izingcezu ze-Tricone drill zingahlukaniswa ngezigaba ezimbili:

i. Ama-Tricone Bits Amazinyo Aqoshiwe (ama-MT Bits):

Amamodeli okuqala ama-MT bits ayenama-cone amabili, lapho amazinyo nemihuzuko kuma-cone kwakungathintani ngesikhathi sokujikeleza. Ukuxhumana phakathi kwamazinyo kuma-cone aseduze kuhlinzeka ngokuzihlanza, kwandisa izinga lokungena, futhi kwenza kube lula inqubo yokubhoboza. Ama-tooth bits agayiwe asetshenziswa ekwakhekeni okuthambile kuya kokuphakathi nokuqina.

ii. Ama-Drill Bits e-Tungsten Carbide Insert (TCI):

Ama-bits e-Tungsten Carbide Insert (TCI), abizwa nangokuthi ama-button bits (isb., uhlobo lwe-MT), aqukethe ama-cone ajikelezayo. Ngokungafani nama-bits e-MT, lawa ma-bits afakwe izinkinobho ze-tungsten carbide kuma-cones emazingeni okushisa aphezulu kakhulu okufakwa. Asetshenziselwa ukusebenza ezindaweni eziqinile nezigqwalayo ezindaweni ezingajulile ezingaphansi komhlaba. Ekujuleni okukhulu, ama-tricone bits abonisa ukusebenza okubi futhi kuthatha isikhathi ukuwashintsha.

2. Ama-Fixed Cutter Drill Bits

Amabhithi okusika aqinile akhiwe ngendlela eyodwa futhi awanazo izingxenye ezihambayo. Eqinisweni, lolu hlobo lwebhithi alunawo amakhoni ajikelezayo ngokuzimela; kunalokho, lunomzimba webhithi ongaguquki kanye nekhanda eliqinile elijikeleza kanye nepayipi lokubhoboza kanye nentambo yokubhoboza. Umzimba oyinhloko walawo mabhithi wenziwe ngensimbi noma i-tungsten carbide. Amabhithi omzimba wensimbi anokumelana okuphezulu nokushaywa kanye namandla asetshenziswa kubasiki, kodwa insimbi inokumelana okuncane nokuguguleka okubangelwa uketshezi lokubhoboza. Ngokuphambene nalokho, amabhithi omzimba we-tungsten carbide anokumelana okuphezulu nokuguguleka kodwa awamelani kangako nokushaywa.

i. Izingcezu Zokusika Insimbi

Lezi zingcezu zihlukaniswe ngezigaba ezimbili: izingcezu zokusika insimbi kanye nezingcezu zomsila wenhlanzi, kanye nezingcezu zokudonsa. Izingcezu zokudonsa zisetshenziselwa ukubhoboza ezindaweni ezithambile embonini kawoyela negesi. Izingcezu zokudonsa zaziwuhlobo lokuqala lwezingcezu ezisetshenziswa ekubhobozeni okujikelezayo, kodwa kancane kancane zathathelwa indawo yizingcezu zekhoni ngenxa yokusebenza kahle okuphansi. Lezi zingcezu zihlonyiswe ngezingcezu zokusika insimbi futhi zisetshenziswa kakhulu ekubhobozeni izindawo ezithambile. Imvamisa yokusetshenziswa kwazo yehlile ngenxa yokusebenza kahle ezindaweni eziqinile; lapho kufakwa imithwalo ephezulu ebhithini, izingcezu zokusika insimbi zizongena ekwakhiweni, futhi ukwanda kwe-torque yepayipi lokubhoboza kungabangela ukuthi ipayipi lokubhoboza liphuke futhi liwele emgodini. Lolu hlobo lwezingcezu kunzima ukulawula indlela ye-wellbore futhi luvame ukuphambuka endleleni eyinhloko.

ii. Izingcezu Zokubhoboza Idayimane

Kulolu hlobo lwe-bit, izinhlayiya zedayimane zifakwa emzimbeni we-bit. Idayimane, into eyaziwayo kakhulu, yakhiwe nge-carbon emsulwa. Ngenxa yobunzima bayo, lezi zinhlayiya zifaneleka kakhulu ekubholeni ezindaweni eziqinile ezirhabaxa. Uma kuqhathaniswa nezinhlayiya zokusika ezigoqayo kanye nezinhlayiya zokusika zensimbi, izinhlayiya zedayimane azizweli kakhulu odakeni lokubhoboza. Udaka lokubhoboza oluxubile luvame ukuthuthukisa ukusebenza kahle kwezinhlayiya futhi luyonga kakhulu.

Ama-diamond bits anikeza izinzuzo eziningi, okuhlanganisa isivinini sokubhoboza esikhulayo kuzo zonke izinhlobo ezahlukene zezakhiwo kanye nezendlalelo zamatshe, isikhathi esincishisiwe sokukhubeka kanye nokuguguleka kwama-bit, asikho isidingo sezingxenye ezisele, kanye nokufaneleka kwemithombo enomfutho ophezulu kanye nezinye izimo ezikhethekile.

Ukuhlukaniswa Kwezingcezu Zokubhoboza Idayimane

• Amabhithi Okubhoboza Amadayimane Emvelo
• Amabhithi Amancane Edayimane Acwebezelayo (i-PDC)
• Ama-Polycrystalline Bits Azinzile Ngokushisa (TSP)

Amabhithi Amancane Edayimane E-Polycrystalline (PDC):

Ama-bits e-PDC anomzimba we-tungsten carbide onezicucu ezifakwe phezu kwayo. Lawa ma-bits angaklanywa ngama-nozzles noma angenawo. Ubukhulu bezinhlayiya zedayimane ku-PDC buthinta ukumelana kwazo nokushaqeka kanye nokumelana nokuguguleka. Idayimane yokwenziwa, ekhiqizwa kusetshenziswa i-cobalt njenge-catalyst, yenza i-PDC ingamelani nokushisa kakhulu kunedayimane yemvelo. Uma ishiswa, i-cobalt iyakhula futhi ingabangela ukuqhekeka kwedayimane.

• Ama-Polycrystalline Bits Azinzile Ngokushisa (TSP):

Ama-TSP bits athuthukiswe ukuze kulungiswe imikhawulo yokumelana nokushisa kwama-PDC bits. Ngesikhathi sokukhiqiza, i-cobalt isuswa nge-acid leaching, noma i-silicon carbide isetshenziselwa ukuthuthukisa ukumelana nokushisa. Ngenxa yalokho, ama-TSP bits adlula ama-PDC bits ezimweni eziqinile kakhulu.

• Izingcezu Zokubhoboza Zedayimane Zemvelo

Izingcezu Zokubhoboza Amafutha

Inhloso Yokubhoboza: Ukubhoboza kuyinqubo ebalulekile kanye nethuluzi lokuhlola nokuthuthukisa izinsiza zikawoyela negesi. Emsebenzini we-petroleum geological, inhloso eyinhloko yokubhoboza ukuthola idatha yezinto ezingaphansi komhlaba, okuhlanganisa ukuqoqa amasampula angokoqobo njenge-cores, i-mineral cores, i-cuttings, i-fluid, kanye ne-gas ezivela emgodini womthombo.

Ukusetshenziswa Kwezingcezu Zokubhoboza Embonini Kaphethiloli

Njengesiteshi sokuloba se-geophysical, senza kube lula ukuthola idatha ehlukahlukene ye-geophysical evela ekwakhiweni kwamatshe angaphansi komhlaba kanye namaminerali. Njengesiteshi sokwenziwa, sivumela ukubonwa kwezimo ze-geological ezingaphansi komhlaba kanye nokuguquguquka koketshezi olungaphansi komhlaba. Ama-Wellbores asetshenziselwa ukukhipha uphethiloli ongaphansi komhlaba, igesi yemvelo, amanzi angaphansi komhlaba, kanye nezinsiza ze-geothermal.

Ubuchwepheshe bokubhoboza busetshenziswa ekuhloleni nasekuthuthukiseni uwoyela negesi yemvelo, futhi ikakhulukazi buhlanganisa:

• Umklamo we-Wellbore
• Ukukhethwa kwezingcezu zokubhoboza kanye noketshezi lokubhoboza
• Ukuhlanganiswa kwamathuluzi okubhoboza
• Ukuhlanganiswa kwemingcele yokubhoboza
• Ukulawula ukuphambuka komthombo
• Ukwelashwa koketshezi lokubhoboza
• I-Coring
• Ukuvimbela nokusingatha izingozi

Ubuchwepheshe bokubhoboza uphethiloli bubonakala ngokujula komthombo ojulile, umfutho ophezulu, izinga lokushisa eliphezulu, kanye nezici eziningi ezithonyayo.

Izinhlobo Zezingcezu Zokubhoboza Uphethiloli

Ngokusekelwe ezimweni ze-geological nezendawo kanye nezidingo zobunjiniyela zokuhlola nokuthuthukisa uwoyela negesi, imithombo ingahlukaniswa ngezigaba ezimbili: imithombo eqondile kanye nemithombo eqondisa izinto. Imithombo eqondisa izinto ingahlukaniswa kabanzi ibe imithombo eqondisa izinto evamile, imithombo evundlile, kanye nemithombo ehlanganisiwe.

Izinhlobo zezingcezu zokubhoboza zifaka phakathi izingcezu ze-PDC kanye nezingcezu ze-Tricone. Izingcezu ze-PDC nazo zisetshenziswa kabanzi emisebenzini ejwayelekile yokubhoboza uphethiloli, okunikeza izinzuzo ezifana nokusebenza kahle okuphezulu kanye nokusebenza okuzinzile.

Okokuqala, ngokusekelwe ekwehlukeni kwezinto zokwakha, ama-PDC bits angahlukaniswa abe ama-PDC bits ensimbi kanye nama-PDC bits e-matrix-body.

I-GREAT ifakwe isofthiwe yokwenza ngcono amapharamitha okubhoboza. Isebenzisa amakhompyutha kagesi njengethuluzi kanye nezindlela zokwenza ngcono, isungula amamodeli ezibalo futhi ithuthukise izinhlelo ngokusekelwe kusimiso sezindleko ezincane, ifaka izici ezahlukahlukene ezingalawuleka ezithinta isivinini sokubhoboza (njengohlobo lwebhithi, ingcindezi yebhithi, isivinini sokujikeleza, ukusebenza kodaka, kanye nezici ze-hydraulic). Lawa mamodeli asetshenziselwa ukwenza ngcono nokuxhumanisa imisebenzi, okwenza amaphrojekthi okubhoboza afinyelele ikhwalithi ephezulu, isivinini esiphezulu, kanye nezindleko eziphansi.

Ubuchwepheshe Bokukhipha I-Core Besebenzisa Ama-Oil Drill Bits

Ubuchwepheshe bokukhipha i-core buhilela ukubhoboza amasampula edwala (ama-core) kusukela ezikhawulweni eziqondiwe emigodini ngokwezidingo zomklamo, ukuthola idatha yokuqala yokuhlola nokuthuthukisa izindawo zokugcina uwoyela negesi.

Amathuluzi avamile okuhlanganisa izinsimbi ahlanganisa kakhulu amadivayisi okuhlanganisa idayimane, imiphongolo eyinhloko, ukubamba izinsimbi eziyinhloko, kanye namajoyinti. Ngesikhathi sokuhlanganisa izinsimbi, i-bit iqhubeka nokusika idwala elingaphansi kwembobo ngendlela eyindilinga, okuvumela insimbi eyisilinda ebhoboziwe ukuthi ingene emphongolweni eyinhloko ngokuqhubekayo.

Ukuze kuhlangatshezwane nezidingo ezikhethekile zokwakheka okuxekethile kakhulu nokuqhekekile, izindlela namathuluzi akhethekile okubopha ayatholakala, okuhlanganisa ukubopha okuvaliwe, ukubopha okulawulwa yingcindezi, kanye namathuluzi okubopha imikhono yerabha.
