I-Core Bit ekhulelweyo
Uyilo lwe-ROP ephezulu xa kusombiwa ubunzulu kunye nobunzima, i-PDC yokomba isoloko iqhelana ukusuka emhlabeni ukuya ezantsi ngokuthe ngqo nangaphantsi okanye kwinto enye, ukugcina ixesha kunye neendleko.
Umahluko kwi-tricone bit, i-PDC drill bit ibaleka nge-WOB esezantsi kodwa i-RPM ePhakamileyo, ke ihlala isebenza ngeemoto ezantsi ukuya kwisantya esijikelezayo.
Ukusebenza kwe-PDC drill bit kuxhomekeke kakhulu kubasiki be-PDC, sinika isisombululo esikhethekileyo kwiimfuno ezithile kulwakhiwo olwahlukeneyo.
Ukubhola ngokwendlela enzima kakhulu kulungele ukulungiswa koxinzelelo ngendlela enzima kakhulu, njengelitye lentlabathi.

I-Core Bit ekhulelweyo yokuGqibezela iiNkonzo
kulwakhiwo olunzima kakhulu kwaye lunzulu
IINGXAKI
Unzima kakhulu kwaye ulwakhiwo olungqwabalala
Ubunzulu bumalunga ne-4,000 yeemitha
Isicelo sokufumana kwakhona
ISISOMBULULO
Ukulungiselela ukusombulula ezi ngxaki, i-DeepFast ibonelela nge-Core Bit 8 1/2 "x 4" DIC280 ukufezekisa le njongo kubume obunzulu nobunzima.
IZIPHUMO
Ngobuncinci bokusika i-1 yeemitha ezili-15 kukubaleka kabini. ukusuka kwi-3805 ukuya kwi-3920 yeemitha
Ixesha lokubeka i-coring limalunga neeyure ezingama-20, kunye ne-ROPIS 5.75 m / h
Umgangatho wokubuyisela ungaphezulu kwe-85%
Ushwankathelo
Kwi-Liaohe Oilfield e-China, umqhubi we-Liaohe Oilfield Coring Technology Services wayecwangcise ukubhola kumthombo onzulu weemitha ezingama-3805. Ubume bunzima kakhulu kwaye i-lithology yigranite enamandla okucinezela ngaphezulu kwe-24000PSL. Injongo yayo yayikukubethelela icandelo lomngxuma we-8 1/2 ”wequla ukubuyisela ukubumba okunzima. Isuntswana esiqhelekileyo se-PDC sasinenqanaba eliphantsi lokufumana kwakhona kunye nokusikwa okungaphantsi. Ke ngoko i-Deepfast ibonelela ngesixhobo sayo esitsha esiCwangcisiweyo se-Core Bit ukufezekisa le njongo kubume obunzulu nobunzima.

Iziphumo
Umsebenzisi wancoma le projekthi njengomsebenzi ogqwesileyo. Olu Cwecwe oluCwangcisiweyo lwe-8 1/2 "x 4" ye-DIC280 ifezekise i-115 yeemitha ezisisiseko ezisikwe nje ngemigangatho emibini kubunzulu ukusuka kwi-3805 ukuya kwi-3920 yeemitha. Ixesha elipheleleyo lilonke ziiyure ezingama-20 ezigcina ii-run ezimbini kunye neeyure ezingama-24 oko kuthetha ukonga i-128,000 RMB. Ngapha koko, umndilili we-ROP yi-5.75 m / h kwaye inqanaba lokufumana kwakhona lingaphezulu kwe-85, ekwadlula kulindelo. Izitshixo zokuphumeza le ntsebenzo yayiyilo loyilo oluncinci kunye nokuphuculwa ukuze ikwazi ukuhlangabezana nolwakhiwo olunzima kakhulu nolurhabaxa. I-DeepFast ayiphuculanga kuphela ukomelela kwezixhobo ze-coring ezilungiselelwe iintlobo ezahlukeneyo zerwala, ikwacwangcise ukufakwa okufakelweyo kunye noyilo lwesithsaba olugobileyo ukunyusa izinga lokubuyisa kunye ne-ROP.
