Yiziphi ezinye izinto ze-Drill Bit Design Factors ezihlobene Nomzimba Webhithi?

Kunezici ezi-2 ezibalulekile ezithinta ukwakheka kwebhithi yokubhoboza okuyizinto i-engeli yejenali kanye ne-engeli ye-offset

2^ndIsici Sokuklama : I-Tricone Drill Bit Watercourses

Ingxenye ebalulekile ye-tricone Drill Bits Design imigudu yamanzi, ngaphandle kwalokho amanye ama-rock bits awakwazanga ukusebenza njengoba bekuhlosiwe.Imigudu yamanzi iyimigudu yoketshezi olujikelezayo, oluletha ngokuyinhloko ukusikwa phezulu futhi luhlanze ukwakheka ngaphansi kwebhithi.Idizayini yemibhobho yesihlabathi yomhubhe eqondisa uketshezi kancane ihlukanisa phakathi kwezinhlobo ezimbili zemigudu yamanzi:

1.imigudu yamanzi evamile eqondisa uketshezi kubasiki

2.imigudu yamanzi ejethi eqondisa uketshezi phansi kwembobo.

Uketshezi lokumba ludlula ku-Drill String futhi luphume ngemibhobho ebhithi.Njengoba idlula ebusweni bebhithi ithwala ukusika okubhoboziwe kusuka kumakhoni kuya ku-annulus.Idizayini yasekuqaleni yamabhithi edwala yavumela kuphela udaka lokumba ukuthi lukhishwe phakathi nendawo.Lokhu akuphumelelanga kakhulu futhi kwaholela ekwakhekeni kokusikwa ebusweni bebhithi (kancane ibhola) kanye nokuguguleka kwekhoni.

Ngakho-ke kwethulwa indlela ephumelelayo yokuhlanza ubuso be-bit.Uketshezi manje ngokuvamile lukhishwa ngamabhomu ejethi amathathu azungeze ingaphandle lomzimba omncane.Isiyaluyalu esidalwe yi-jet stream kwanele ukuhlanza abasiki kanye nokuvumela ukumba okuphumelelayo ukuqhubeka.
