Dubeyaasha DTH ee dhagxaanta dhagaxyada yar yar ee wax qodista oo iib ah
Sharaxaada Alaabta
Waxay soo saartaa badhanno fara badan oo kala duwan si ay ugu habboonaato dhammaan noocyada iyo cabbirrada dhammaan noocyada caanka ah ee dubbayaasha godka hoose.
Waxaa lagu heli karaa qaabab kala duwan oo madax ah iyo qaababka badhanka, waxaa loogu talagalay in lagu siiyo qodayaasha fursad ay ku doortaan inta ugu fiican ee si hufan loo qodayo dhammaan noocyada dhagaxyada kala duwan iyo xaaladaha dhulka.
Dhammaan qaybaha dhexdhexaadka ah waxay ka samaysan yihiin birta nikkel ee sare, taas oo ah kulaylka lagu daweeyo si loo soo saaro dusha sare ee ka hortagga daalka iyo xirashada.
DTH (Down to Hole) birta qodista, sidoo kale loo yaqaan spline-ku xiran, inta badan waxaa lagu isticmaalaa miinada baaxadda weyn (furan iyo dhulka hoostiisa), dhagaxa furan iyo dhismaha.Dubbadu waxay ku taallaa godka si toos ah ugu xidhan birta laydhka oo kabooyinku ku dhex jiraan.Piston dubbe ayaa ku dhufanaya birta daloolka taasoo keentay gudbinta hufan ee tamarta saamaynta iyo khasaaraha tamarta aan macno lahayn ee qoto dheer godka.

Sida loo doorto DTH Bits qaabka wajiga iyo Qaabka Button Carbide
J: Doorashada qaabka wajiga
Hoosta Xarunta Bit
Heerarka dhexgalka sare ee jilicsan ama dhexdhexaad-adag iyo qaababka dhagaxyada jeexan.
Waji qallafsan
Codsiga wareega oo dhan wejiga qaniinyada si gaar ah loogu talagalay samaynta dhagax adag oo dhexdhexaad ah iyo mid isku mid ah.Kontoroolka leexashada godka wanaagsan iyo awoodda daadinta wanaagsan.
Wajiga Convex
Heerarka dhexgalka sare ee jilicsan ama dhexdhexaad-adag oo leh cadaadis hawo hooseeya ama dhexdhexaad ah.Waa iska caabbinta ugu badan ee dhaqista birta, iyo iska caabbinta wanaagsan ee birta dhaqida birta xoogaa cabbirka.
Waji fidsan Bit
Qaabka wejiga noocan oo kale ah wuxuu ku habboon yahay si adag oo aad u adag iyo qaababka dhagaxyada naxaasta leh ee codsiyada leh cadaadiska hawada sare.Gelitaanka wanaagsan wuxuu qiimeeyaa caabbinta dhaqidda birta.
B: Geli badhanka qaabka xulashada
Badhan kala duwan ayaa ku habboon xaaladaha kala duwan ee dhulka, heerarka xoqidda, PSI iyo heerarka dhexgalka.Guud ahaan, inta badan ee badhamada cabbirka, ayaa ka sii fiican waxqabadka, gaar ahaan dhagax adag.
Goobaysan
- Codsiga Xoog-ujeedo badan
- Sida ugu fiican ugu habboon xoqidda jilicsan
- 25,000 ilaa 45,000 PSI (170 ilaa 300 MPa)
- Naaxsan oo aad u xoqan
Badhanka Ballistic
- Codsiga Xoog- galinta degdega ah
- Sida ugu fiican ugu habboon dhulka jilicsan
- 10,000 ilaa 20,000 PSI (70 ilaa 140 MPa)
- Dhul aan xoqin
Semi-ballistic
- Codsiga Xoog-soo-gelidda
- Sida ugu fiican ugu habboon dhulka dhexdhexaadka ah

Astaamaha birta daloolinta ee Nickel-alloy
1) Kalsoonida
Bistoonada DTH Hammer waxay isticmaashaa birta daawaynta sare ee nikkel ee gaarka ah (la soo dejiyay), oo leh daawaynta kulaylka horumarsan oo ah heerka warshadaha militariga.
Xoojinta habaynta dusha dubbaha si sare loogu qaado caabbinta.
2) Ku haboonaanta
Qodayaal si gaar ah loo nashqadeeyay oo loogu talagalay qaab-dhismeedka dhagxaanta jilicsan iyo kuwa adag.Si fudud u kala furfur dunta si ay u fududaato dayactirka.
3) Waxtarka
Naqshadaynta qaab-dhismeedka gaaban ee dheeriga ah ee DTH dubbe iyo xoogaa loogu talagalay waxtarka weyn ee gudbinta tamarta saameynta sare leh, oo leh awood saameyn sare leh iyo heerka qodista degdega ah.
Hammer iyo xoogaa naqshadeynta waxaa lagu hagaajiyay jilitaanka kumbuyuutarka, oo leh qolka qaybinta hawada ugu fiican iyo naqshadaynta cidhiidhiga hawada.
