Giling Tricone Rock Drill Bits:
Giling waos (waos baja) tricone bit pengeboran kanggo tatanan rock alus kanggo medium.
Tatanan alus tricone waos gilingan bit digunakake kanggo pengeboran kurang kekuatan compressive, tatanan alus.Dawane untu proyeksi dawa digunakake ing kerucut offset dhuwur kanggo nyedhiyakake tingkat penetrasi paling gedhe.Wear resistance hard facing digunakake kanggo ngontrol nyandhang untu.Ing jinis bit sing paling lembut iki madhep hard rampung nutupi untu dicokot.
The medium formasi giling tricone bit digunakake kanggo pengeboran kekuatan compressive dhuwur, tatanan rock medium.Uji proyeksi tembak kanthi dawa crest suda digunakake ing seri desain bit iki.Awet hard madhep ditrapake kanggo nyuda nyandhang waos.
Tabel klasifikasi kekerasan formasi lan pilihan bit
| Rol cone bit | kode IADC saka diamond bit | Katrangan formasi | Tipe rock | Kekuwatan kompresif (Mpa) | ROP (m/h) |
| kode IADC | |||||
| 111/124 | M/S112~M/S223 | Alus banget: tatanan alus lengket kanthi kekuatan tekan sing sithik. | lempung Siltstone sandstone | <25 | > 20 |
| 116/137 | M/S222~M/S323 | Soft: tatanan alus karo kekuatan compressive kurang lan drillability dhuwur. | Batu lempung Marl Lignite sandstone | 25~50 | 10~20 |
| 417/527 | M/S323~M/S433 | Sedheng alus: tatanan alus nganti medium kanthi kekuatan tekan lan steak sing kurang. | Batu lempung Marl Lignite watu pasir Siltstone Anhidrat Tuff | 50~75 | 5~15 |
| 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 |
