Mokhoa oa ho khetha PDC e boreleli?

1. Ho thatafala: Tlholisano ea thata le ho feto-fetoha le maemo

Letšoao la Core: Bokhoni ba Lefifi ho hanela Deformation kapa ho cheka.

Mathata ka majoe a thata (a joalo ka granite, thata e phahameng e lebisa ho phatloha ha meno le ho roala hampe. Litšobotsi tsa li-bits tse loketseng:

Meno a Phapang ka matla a ho khaola: boleng bo phahamengPDC Cutterka ho hanyetsa ho thata ho hanyetsa matla a matla le botsitso ba futhumatsang bo botle ba lokela ho khethoa.

Moralo oa lehare le boima: matlafatsa matla a sebopeho sa 'mele oa lehare oa ho hanela lefika la lejoe.

Nako e nyane ea ho cheka: li-angles tse mpe tse mpe (joalo ka -15 °) hangata li amoheloa, haholo-holo bakeng sa ho "hlakola" ho fokotsa ho kenella ha Brittle.

Morero oa ts'ireletso ea litereke tsa litereke tsa gauge: thibelamonyebebophara ho tloha ho fokotsa kapele ka lebaka la ho roala ka botebo.

2. Li-steagenness: Teko ea mantlha ea ho tšoarella

Letšoao la Core: Bokhoni ba lefika ba ho roala meno lemonyebemmele (o amanang haufi le dikahare tsa liminerale tse thata joalo ka quartz).

Limakana tsa majoe tse ntle haholo (joalo ka Quartsz Sandston Aundstone, granite e nang le mokokotlo oa chertse, likala tsa chett):

Litšobotsi tsa tse loketsengli-bits tsa Drill:

Meno a sehiloeng a ho kuta-likela a ultra: Sebelisa likarolo tsa PDC tse nang le botsitso bo phahameng ba botsitso le ho ba matla ho apara.

Morero oa Tofatso ea Tofatso ea meno: eketsa palo ea ho kuta meno ho arolelana mojaro o le mong.

Phetoho e ntlafalitsoeng ea hydraulic: netefatsa ho tlosoa hoa li-cutlets ho qoba ho apara ka tlasa ho ts'oaroa ka botlalo ka lebaka la slindary ea bobeli.

Libaka tse matlafatsang tsa lekanyelitsoeng / tse sa aroheng.

3. Sebopeho sa sebopeho le homogeneity: Ho ikamahanya le maemo a rarahaneng

Mabaka a Coretion: Tekanyetso ea Nts'etsopele ea Meroallo: Manonyeletso a manonyeletso a mekhabiso ea lefika, le boemo ba ho fapana le likarolo tse thata le tse bonolo.

Mefuta e rarahaneng (joalo ka libaka tse pharalletseng tsa molato, letsoalloa le manonyeletso a ntlafalitsoeng ka matla, Sandstone-mudsetone.

Litšobotsi tsa tse loketsengli-bits tsa Drill:

Moralo oa botsitso: Moralo oa Tekanyetso e Ntlemonyebelibakeng tse robehileng kapa likarolo tse bonolo.

Sebopeho se sehiloeng se sehiloeng: E ka ba boholo bo kopaneng kapa boqapi bo tlase ba angle tsa morao-rao ho matlafatsa maemo a makeuli a majoe a heterognenonous rock.

4. Paramente ea ho cheka: Mothati oa ts'ebetso

Core Corexing: Boqapi bamonyebee hloka ho tsamaisane le maemo a lebelletsoeng a boima ba boima ba 'mele bo boholo (wob) le lebelo la ho potoloha (rpm).

Lintlha tsa Bohlokoa:

Phahameng wob / e tlase rpm: hangata e loketse maikutlo a thata, a hlokamonyebeho ba le sebopeho se matla (joalo ka menoana e tenang) le meno a sa koahetsoeng a sephiri.

Low Wob / High Rpm: E loketse ho ba bonolo ho e-ba bonolo - Themonyebee ka etsoa ka monko o monate o sephara a khomarela meno le sebopeho sa hydraulic se kopa ho tlosa chip.

Parameter Boinyenyefatso: Le haeba ho taka hanyane ka boeona bo loketse lipapatso tse thata, tse kang litlatsetso tsa pele ho nako kapa katleho e tlase.

5. Mefuta ea PDC Drill Bit: E mong le e mong o ikhethile

Classization ea Core: Ho latela lipheo le lipakane tsa moralo, ho na le mefuta ea mantlha eaPdc Drill Bot:

Mofuta oa maemo a tloaelehileng: o fetotse, o loketseng ho mahareng a mahareng - homote)

Mofuta oa ntlafatso / o thibelang mofuta oa tšusumetso o ntlafalitsoeng, meno a matla a mangata

Mofuta o hatellang haholo: Ho sebelisa lisebelisoa tse sa senyeheng haholo, tlhophiso ea meno e senyehileng le ho hlophiseha ka mefuta e sa tloaelehang (joalo ka Quandstone ea quandstone).

Mofuta o tebileng / oa ultra-Ultra-Ultra-setulong se ikhethileng ho botsitso le ho ts'epahala ho lintoa tse phahameng le tse phahameng.
