PDC HDD (Horizontal Directional Drilling) Drill Bits
Tlhaloso ea Sehlahisoa
Likotoana tsena tsa HDD tse batlang li sa senyehe le tse kentsoeng li ka mamella libaka tsohle tse thata le likhechana tse thata tseo ho cheka ho ka u lahlelang tsona. Hore na o cheka lehlohlojane kapa litšila, Grand Construction e na le boro e nepahetseng kapa e kenyellelitsoeng morero oa hau.
Likotoana tsa ho cheka tsa PDC HDD li ka phunya matlakala a mahareng ho isa bohareng. Ho kgothaletswa ho cheka shale, seretse, Lejwe la Semented Sandstone le carbonate rock ka matla a mahareng a kgatello. Re na le likhetho tse ngata tsa ho bopa HDD, joalo ka li-pilot tsa milled-tooth bakeng sa libopeho tse bonolo le tse hlephileng. Ka ts'ireletso e ntlafalitsoeng ea lesela, tšepe e thata holim'a bevel le ho tsoa ka hare ho cone, li-pilot bits li ka mamella maemo a thata a ho cheka a atisang ho kopana le lits'ebetso tsa HDD.
O mong oa melemo ea mantlha ea li-drill tsa rona tsa HDD ke bokhoni ba tsona bo ikhethang ba ho tsamaisa, bo ba lumellang hore ba tsamaise ka nepo le lits'ebetso tse thata ka ho fetesisa tsa ho cheka. Hore na u ntse u cheka ka tlas'a seterata sa toropo kapa ka tlas'a noka, u ka tšepa li-drill tsa rona tsa HDD ho fana ka ts'ebetso e nepahetseng le e tšepahalang nako le nako.
Ntle le bokhoni ba bona ba ho cheka le ho tsamaisa, Li-Bits tsa rona tsa Horizontal Directional Drilling li boetse li etselitsoe ho fokotsa ho thothomela le ho fokotsa ho senyeha ha lisebelisoa tsa hau tsa ho cheka, ho thusa ho lelefatsa nako ea bophelo ba lisebelisoa tsa hau le ho fokotsa nako ea ho theoha mererong ea hau ea ho cheka.

Ho fapana le li-bits tse tloaelehileng tse tataisoang ke PDC, li-bits tsa rona tsa Grand Construction li fana ka melemo e mengata ea moralo, ho kenyelletsa:
Moralo o atolositsoeng oa profil bakeng sa ho cheka ka potlako ho sebopeho sa mafika.
Li-stabilizer tse hahiloeng bakeng sa botsitso bo ntlafetseng ba kholomo ea ho phunya.
Lisebelisoa tse ngata tsa PDC bakeng sa bophelo bo bolelele ho feta li-drill tse tloaelehileng tsa PDC.
Li-bits tsa rona tse tloaelehileng tse tataisoang ke HDD li fumaneha ka boholo ba 5-1/2" le 6-1/2". Karolo e 'ngoe le e 'ngoe e na le moralo oa rona oa 5-blade o tšoarellang le o hlomphuoang haholo, ho kenyeletsoa sesebelisoa sa PDC sa 13mm, bakeng sa ts'ebetso e nepahetseng, e nepahetseng le e sebetsang hantle morerong ofe kapa ofe oa ho cheka mafika. ![Fektheri17px](https://ecdn6.globalso.com/upload/p/365/image_other/2024-01/659b6e764913857309.jpg)
