Ka ho cheka ha khase ea tlhaho, khetho e pakeng tsa hamore ea ho theola Ka tlase ke papiso ea lits'ebetso tsa bona tse peli le tse tloaelehileng:

1. The-the-the-lesoba (dth) 

Molao-motheo oa ho Sebetsang:  

  E sebelisa khase ea khatello e phahameng (air / naetrojene) ho khanna piston e amang motsoako oa ho kopanya  

Melemo:  

Ts'ebetso e phahameng lefikeng le thata: Tsela e holang ka lebelo la ho cheka ka thata, ho bolotsana kapa ho brittle mefuta e kang granite le basalt (makhetlo a 2-3 e potlakileng ho feta roller gene cnets).  

Tšenyo e tlase ea pokello ea polokelo: Ho potoloha ha mafura ho fokotsa tlhaselo ea metsi (e loketse khatello e tlase kapa ea ho phomola).  

  Ho feto-fetoha ha maemo  

Litsietsi:  

Ho Tšepahala: ho hloka compressorm kapa jeitrogen jenerate ea linate, litšenyehelo tse ntseng li eketseha.  

 Meeli e tebileng: Molemo ka ho fetisisa bakeng sa ho teba ho Weds tse bohareng (3 3,000 Meter); Phetisetso ea mafura e potoloha e fokotseha lilibeng tse tebileng.  

  Ha e khonehe ho mefuta e bonolo ea ho itlosa bolutu: ho fanoa ka ho bolotsana ka lebaleng kapa seretse.  

Kopo e tloaelehileng:  

 Ho cheka ha khase e sa tebang ho khase e thata kapa shale khase (e.g., moea, ho cheka lebese).  

  Li-Weds tsa ho hlahloba Wells kapa ho cheka ho taka ho thata  

 Libaka tse se nang metsi: Ha ho metsi a tsamaisoang ka metsi a hlokahalang.  

2. Roller gene hanyane

Molao-motheo oa ho Sebetsang:  

  Li-cones tse potolohang li hahlaula le Shearc ha li ntse li tsamaea le litsiso.  

Melemo:  

  Qatolotsa: Ho feto-fetoha ha ho le thata ho li-formation tse bonolo (tse thata  

  Kamohelo e tebileng - e loketseng liliba tse tebileng (> limithara tse 3,000) le khatello e phahameng ea mocheso.  

limithara tse 3,000) le khatello e phahameng ea mocheso.  

  Ho sebetsa ka theko e boima: litšenyehelo tse tlase tsa upfrond, theknoloji e holileng le kokelo e ntle (e.g., moferefere).  

Litsietsi:  

  Ts'ebetso e tlase lefikeng le thata: o apara ka tsela e thata haholo, e hlokang hore e be teng.  

  Sebaka sa polokelo ea polokelo ea morao-rao: Ho potoloha ha mud ho ka ba teng (ho hloka lijo tse tahiloeng).  

  Mathata a Tšokelo: Taolo e sa nepahalang ka lilibeng tse otlolohileng ha e bapisoa le likheo tsa PDC kapa dth.  

Litšitiso tse tloaelehileng:  

  Liliba tse tloaelehileng tsa khase e hlakileng: Ho cheka ha pota-potisisa ka mefuta e thata ea mahareng (lehlabathe, mudstone).  

  Li-forervories tse tebileng tsa khase: tse pakiloeng ka seretse sa boleng bo holimo ho lekanyetsoang ho leka-lekanyelitsoeng.  

  Mefuta e rarahaneng: Libaka tse kopaneng kapa tse sephara (botsitso bo ntlafalitsoeng ka moralo oa meno).  

3. Lintlha tse ling

Likhathatso tsa PDC: Ho cheka ha khase ea tlhaho, polycrystalline daes e boetse e sebelisoa haholo, haholo-holo ha ho sebelisoa khaselletsong, haholo-holo ho hanyetsa ha khase e otlolohileng le ho khaola.  

Ts'ebeliso ea Hybrid: Li-bits tse fapaneng li ka sebelisoa ka mekhahlelo, e.g.  

  Dth bakeng sa likarolo tse thata tse thata, li fetohela ho Roller Cone e bilika e tebileng litabeng tsa ho teba.  

   Pdc bits likarolo tse otlolohileng, li-cooller tsa rolor li kopantsoe ka likarolo tse otlolohileng.  

Dth Hammer: E ne e itsamaela ka lefika le thata, ho cheka khase e sa tebang / ho hatelloa, ho hatisa ts'ireletso le ts'ireletso ea khatello ea matla le khatello ea matla.  

Roller COne Che: E loketse liliba tse tloaelehileng, liliba tse tebileng, likhalase tse tebileng, tse bonolo - tse bonolo, tse bonolo, litšenyehelo tsa ho leka-tekano le ho ba le maemo.
