PDC Cutter bakeng sa PDC Core Bit

PDC core bit e hahiloe ka li-cutters tsa PDC le 'mele oa matrix kapa' mele oa tšepe. PDC core bit e nepahetse bakeng sa ts'ebeliso e nang le lisebelisoa tsa ho cheka tse matla haholo tse sebetsang ka lebelo le tlase la ho potoloha. Empa bophelo le ho kenella ka hare ho ka ba betere haholo ha li bapisoa le likaroloana tse behiloeng holim'a metsi.

PDC core bit e na le lithupa tse ngata tsa sintered polycrystalline-diamond 'meleng oa matrix. PDC cutter e na le likaroloana tsa daemane tsa maiketsetso tse kopantsoeng hammoho ka khatello e phahameng le mocheso o phahameng. Botlaaseng ba lera lena la daemane ho na le tungsten carbide stud e kentsoeng ka har'a 'mele ka kotloloho. Mefuta e 'meli ea mantlha ea li-cutters tsa PDC lia fumaneha bakeng sa PDC core bit: moralo o tloaelehileng oa sephara kapa dome. Li-cutters tsa PDC li behiloe moqhaka 'me li ka amohela meroalo e meholo haholo ea khatello le ho kuta e hlahisoang nakong ea ho cheka. Ho na le li-cutters tse ka bang leshome tsa PDC 'meleng oa matrix, ho latela boholo ba karolo ea mantlha. Ntho e kholoanyane ke hore, palo e phahameng ea li-cutters tsa PDC ho eona.

PDC core bit e na le masoba a phunyang kapa setsi se bulehileng 'me se ka feto-fetoha le molomo o tsitsitseng. Li-nozzles lia hlokahala hobane li fana ka phallo ea jete e ferekaneng ka har'a likotoana ho boloka libaka tse sehang li hloekile.

Mefuta e mengata ea majoe a sedimentary ea homogeneous joaloka shale, dolomite, limestone le sandstone li sebetsoa habonolo ka PDC core bit. Bakeng sa libopeho tse thata tse kang dolomite le limestone, matrix body PDC core bit e sebelisoa hangata hobane e fana ka khanyetso e ntle ea ho roala. 'Mele oa tšepe oa PDC oa mantlha hangata o sebelisoa ha o sebetsa ka libopeho tse bonolo joalo ka sandstone. The core bit e sebetsa ketso ea ho kuta kapa ho kuta ha u kopana le sebopeho. Lebelo la ho potoloha ha core bit le phahame haholo ho feta tse ling tse tloaelehileng tsa rotary. Li-Hydraulics tsa PDC core bit li na le moralo oa ho boloka lesoba le hloekile le likotoana tsa mantlha li pholile, ka hona li eketsa bophelo bo bolelele.

Haeba o khahlehela li-cutters tsa PDC 'me u batla lintlha le lintlha tse ling, u ka ITHUTA KA HO THUSA KA mohala kapa ka poso ka letsohong le letšehali, kapa U RE THUSE MAIL botlaaseng ba leqephe.
