BAJA panggilingan waos bit
IADC 1 séri bor bit
bit ieu dipaké pikeun bor kakuatan low-compressive, formasi lemes.Panjang huntu proyéksi panjang dipaké dina congcot offset tinggi nyadiakeun ongkos penetrasi greatest mungkin.Hardfacing tahan ngagem dipaké pikeun ngadalikeun maké huntu.Dina tipe bit panglemesna hardfacing ieu lengkep nutupan huntu bit.
IADC 2 séri bor bit
bit ieu dipaké pikeun bor formasi teuas tur abrasive.Huntu anu pondok pisan, jarakna raket sareng jumlah hardfacing minimum dianggo pikeun résistansi pegatna.Bit ieu kedah tahan beban anu luhur sareng ngabor formasi abrasive kalayan tindakan anu ngaremuk, motong.

Catetan pikeun pamakéan roller congcot bit:
1 .Before bit bor turun, perlu pikeun ngonfirmasi yén handap sumur beresih, bébas tina grit, sarta euweuh logam ragrag.
2. Pariksa lamun sambungan thread screw bit gilinding congcot gembleng tur nozzle dipasang leres.
3. Ngajalankeun dina liang perlu stabil, nyingkahan setrés jeung nyegah pangeboran.
4. The gabungan panungtungan perlu kapindahan badag pikeun ngamimitian tabel Rotary sarta tetep reaming ka handap sumur., pinuh nyeuseuh sumur pikeun nyegah lebu tina clogging nozzle nu.
5. Bentuk liang handap kudu enteng dipencet sarta lalaunan robah jadi kontak jeung handap sumur, tekanan pangeboran leutik, speed low, kapindahan badag, torsi leutik, sarta speed nyaeta 40 ~ 60 rev / mnt, sahenteuna 30 menit.
6. Nangtukeun beurat dina bit jeung speed dina kombinasi jeung kaayaan sabenerna formasi.
7. Salila pangeboran payun, operasi kudu mulus, bor dahar kudu seragam, eta mastikeun dilarang pikeun ngangkat sarta ngaleupaskeun bor sharply, bor string teu well braked jeung bor string ragrag bébas.
8. Lamun kapanggih yén bit bor eureun nyieun kamajuan, tekanan pompa naek tur turun écés, laju penetrasi dumadakan turun, sarta torsi ngaronjat, angkat bor pikeun pariksa tanpa reureuh.
