Tsananguro yeChigadzirwa

Musoro weWholesale API unotenderera werig yekuchera peturu uripo nemutengo wakaderedzwa kubva kufekitori yeChina
IADC: 215 ndeyemaumbirwo akaomarara ari pakati nepakati ane simba guru rekumanikidza. Isimbi yakavharirwa mazino ine chivharo chesimbi ine dziviriro yegeji.
Ruzivo rwevhu nderwematombo akapfava, asina kupatsanurwa, asina kusimba, anosanganisira matombo ejecha, marl limestones, ivhu risina kusimba, gypsum, munyu uye marasha akaoma.
Chidimbu chetricone chinhu chakakosha pakuboorera. Basa rechidimbu chetricone rinoita kuti dombo re stratum rive rakapfava, rakapwanywa, rakachekwa uye rikwanise kukwira kana ma roller cones achitenderera. Saka, chidimbu chetricone chinogona kuchinjika kune stratum dzakasiyana-siyana dzakapfava, dzepakati nedzakaoma.

12 1/4" i311.1mm, tinowanzoidaidza kuti 311mm. Ihukuru hwakajairika hwepurojekiti yekuchera matombo eoilwell. Iyi tirecne bit yehukuru iyi ichashandiswa pakugadzira michina midiki yekuchera uye inoshandiswa zvakanyanya pasi rose.
Zvakakosha kusarudza saizi chaiyo uye rudzi rwe tricone bit panguva yekuboora. Kuoma kwematombo kwakasiyana, kungave kwakapfava, kwepakati, kwakaoma kana kwakaoma zvikuru. Kuoma kwacho hakuna kusiyana kunyangwe rudzi rumwe chete rwematombo, akadai sekamestone, shale nejecha idombo rakapfava, limestone yepakati neyakaoma, snadstone yepakati nejecha rakaoma.
Saka ndapota tiudzei mamiriro chaiwo, akadai sekuoma kwedombo, rudzi rwechishandiso chekuboorera, ROP (kumhanya kwerotary), WOB (Huremu hwebhiti) uye toque. Zvichabatsira zvikuru kuziva mabhiti akakodzera kana muchikwanisa kutiudza nezvekuboorera kwetsime rakamira kana kubhoorera rakatwasuka, kuboorera kwetsime remafuta kana kubhoorera pasina kuchera kana kuisa hwaro.
