Indlela yokusebenzisa i-PDC drilling bit?

A. Ukulungiswa komngxuma
a）Qinisekisa ukuba umngxuma ucocekile kwaye akukho nkunkuma
b）Sebenzisa intwana yangaphambili ngebhasikithi yenkunkuma ukuba kulindeleke ukuba inkunkuma idliwe

B. Ukulungiswa kwePDC Bit
a） Susa iqhekeza kwibhokisi yokupakisha
b）Inxalenye yokuma phezu komqamelo womthi okanye ngerabha - kungekhona phezu kwedekhi yentsimbi
c） Inombolo yebhithi yerekhodi
d) Hlola ibit ukuze ubone ukuba ayinamonakalo na
e) Screw i-bit nozzles efanelekileyo ngokwendlela eyilwe ngayo injineli yokubhola
f） Jonga ngaphakathi kwento ecocekileyo kwaye engenankunkuma

C. Ukulungisa icandelo
a）Coca uze uthambise iphini kunye nebhokisi
b）Faka i-bit breaker kwi-bit uze ufake i-latch
c） Faka i-bit breaker kwitafile ejikelezayo
d）Yenza iTorque iphakame ngeeTorque ezicetyiswayo

D. Ukukhubeka ngaphakathi
a） Sondela ngononophelo izihlangu/izithintelo zekhava
b）Iindawo ezixineneyo zokuxuba - jonga ukuxuba
c）Ilungu lokugqibela - hlamba ukuya ezantsi
d）Thega ezantsi kancinci ngesantya esiphezulu kunye ne-RPM ephantsi）
e）Jikelezisa imizuzu emi-5

E.Reaming
a）Akukhuthazwa ukuba kufakwe imingxunya engaphantsi kwe-gauge - iindawo ezixineneyo kuphela）
b） Ukuhamba okupheleleyo
c）I-WOB ephantsi - 1/10 ubuninzi. I-WOB
d） Gcina i-ROP ephantsi kunye ne-RPM ephezulu
e）Kuphephe i-torque ephezulu

F. Ukubhoboza ngaphakathi
a） I-WOB ephantsi yokugrumba iprofayili yokusika unyawo lokuqala
G. Ukwenza unxibelelwano
a） Ukuhamba ngokupheleleyo de uKelly anyuke
b） Ukwenza uqhagamshelo
c）Rekhoda uxinzelelo ezantsi nasezantsi
d） Jonga imivumbo yepompo
H. Ukubhoboza phambili
a） Fumana ipharamitha yokugrumba efanelekileyo yokwakheka ngakunye ngaphakathi
Umda ocetyiswayo - ngokutshintsha - WOB - RPM - ukuhamba, Musa ukuseta kwaye ulibale）
Iifomyula ezithambileyo - I-ROP ephezulu inyusa umngcipheko wokuxhuzula
Iintambo eziqinileyo - Yehlisa i-RPM ukuze uphephe ukugqithisa kakhulu
Ukunciphisa i-WOB - i-WOB ephezulu inciphisa ubomi be-bit
b）Uphando - Kucetyiswa uphando oluqhelekileyo

I. Ukukhupha iplagi
a）Iindlela zamanzi ezivaliweyo - ukwanda komahluko woxinzelelo kuvaliwe
kwaye ezantsi
- Ibhuleki yokukhaba
- Gcina ukuhamba okupheleleyo
- Gcina ujikelezo
b）Ii-nozzles ezivaliweyo - ukunyuka koxinzelelo oluphantsi nasezantsi
- Jikelezisa imizuzu emi-5
- Phakamisa uKelly, vumela ukuba awe ngokukhawuleza - thintela ukuntywila
- UNGALAHLISI iqhekeza ezantsi
Ukugrumba eMpuma Ekude yifektri yaseTshayinaIibhithi zePDC,Iibhithi zokubhola zeTricone, iinxalenye eziphambili,Iibhithi ze-hybrid,Iziqwenga zedayimani,Isivulo semingxunya,Iibhithi zokubhola zeHDDeyayisetyenziselwaumthombo weoyile/wegesiukubhola,umthombo wemigodi, ukugrumba imithombo yamanzi ashushu,uphando lwejolojiuphando lwe-hydrography,ukugrumba imithombo yamanzi ,Iiprojekthi zemibhobho ye-HDDkunye neeprojekthi zesiseko.
