Instruksi aplikasi bor bit
1 bit pilihan
1. Mangga maca katrangan litologi lan cathetan bit sumur jejer kanthi teliti, lan nganalisa karakteristik formasi.
2. Milih jinis cocok jumbuh karo litologi.
2 Preparation sadurunge pengeboran
1.Mriksa dicokot sadurungé kanggo karusakan awak, ilang pemotong utawa sisipan etc. Priksa manawa ora ana ajur ing bolongan buttom, lan ngresiki bolongan ngisor yen perlu.
2.Bit kudu ditangani kanthi ati-ati supaya ora ana pemotong karusakan lan bahan sing atos.
3. Priksa manawa ana karusakan ing bit cuttes lan yen ana barang manca ing bit.
4. Priksa manawa nginstall nozzle wis ketemu syarat, lan ngganti nozzles yen perlu.
3 Nandhani bit
1. Bersihake benang lan olesake pelumas ing benang.
2. Pasang breaker menyang bit, murahake senar pengeboran menyang pin lan melu benang.
3.Locate dicokot lan mbobol ing rotary bushing, lan nggawe-up dicokot kanggo dianjurake torsi.
4 Mlebet
1. Copot breaker lan kanthi ati-ati murahake bit liwat piranti wellhead supaya ora ngrusak.
2. Shrinkage, Pundhak, dogleg lan tombol jog saka borehole kudu ati-ati nalika dicokot liwat bolongan kosong.
3.Mulai pompa lan siklus ngebur adi kanggo wisuh buttom bolongan nalika pengeboran kanggo titik bab 30 meter kanggo ngisor bolongan, lan muter senar pengeboran ing kacepetan kurang ora luwih saka 60rpm
4. Nyedhak ngisor kira-kira setengah meter.Sirkulasi kanggo 5 nganti 10 menit kanthi aliran lengkap.
5 Reaming
1.Reaming bagean dawa saka bolongan undergauge ora dianjurake.
2. Yen operasi reaming perlu, iku banget dianjurake sing operasi reaming kudu rampung karo aliran aliran maksimum circulation, bobot tartamtu ing dicokot ora ngluwihi 90N/mm (diameteripun), rotary kacepetan ora ngluwihi 60 rpm ngendi macet ditemoni nalika tripping ing.
6 bit break-in
1.Overusing instruments tampilan nalika dicokot approch bottomhole.Yen WOB lan torsi mundhak, sing nuduhake bit wis attived ing bottomhole.Gunakake ora luwih saka 90N/mm, bobot -on = bit lan 40to 60rpm kanggo netepake pola bottomhole paling setengah meter.
2.Bit break-in wis rampung lan kudu diatur RPM kanggo njupuk kombinasi parameter pengeboran optimal.
3.Pengeboran paramèter imbuhan kudu milih ing watesan saka paramèter dianjurake deleng ngebur dianjurake cara optimasi paramèter.

| 517/537 | M322~M443 | Sedheng: tatanan medium nganti hard kanthi kekuatan tekan dhuwur lan garis abrasif tipis. | Mudstone Watu peteng shale | 75~100 | 2~6 |
| 537/617 | M422~M444 | Sedheng hard: tatanan hard lan kandhel karo kekuatan compressive dhuwur lan abrasiveness medium. | Watu peteng Suku keras Anhidrat watu pasir Dolomit | 100~200 | 1.5~3 |
