Zvimedu zvekuchera zveIndasitiri yeMigodhi

Tricone drill bitsisarudzo yakakurumbira muindasitiri yezvicherwa nekuda kwekuita kwavo kwakasiyana-siyana uye kubudirira mumhando dzakasiyana dzekuchera. Zvibooro izvi zvine misoro mitatu yakabatana ine mazino anopwanya nekukuya dombo apo chibooro chinotenderera. Tricone drill bits inozivikanwa nekugona kwayo kubata maitiro akasiyana, anosanganisira akapfava, epakati uye akaomarara dombo. Iwo zvakare akakodzera kudhirowa kwakatwasuka uye kwakachinjika, zvichiita kuti ive sarudzo inosiyana-siyana yemabasa emigodhi.

Reverse circulation sando uye zviboorochimwe chishandiso chakakosha mumabasa emigodhi. Iyi mhando yemidziyo yekuchera yakagadzirirwa kupa inoshanda uye inodhura-isingadhuri yekuchera mumatombo akaomarara. Reverse circulation method inosanganisira kushandisa sando kudhiraivha bhiti mudombo uchiunza zvidimbu pamusoro nepakati petambo yekuboora. Izvi zvinobvumira kukurumidza kuchera uye zvirinani sampuli kudzoreredza, zvichiita kuti ive yakanaka yekuongorora uye kudhirowa kwekugadzira mumashandisirwo emigodhi.

PDC drill bitsihwo hutsva hwemazuva ano mumigodhi yekuchera. Aya madhiri ekuchera anoratidza madhaimani akachekwa akaiswa kune bit face kuti ape kusimba kwepamusoro uye kushanda mumamiriro ezvinhu akaoma ekuchera. PDC drill bits dzinozivikanwa nekukwira kwadzo kwemazinga uye hupenyu hurefu, zvichiita kuti dzive sarudzo yekutanga yekuda mabasa emugodhi. Vanonyanya kushanda pakuchera kuburikidza nemaitiro akaoma akadai se shale, limestone uye sandstone.

Semutengesi wezvibhorani zvemigodhi kunze kwenyika, unofanira kunzwisisa zvinodikanwa zvakasiyana-siyana zvekuchera migodhi uye nekupa huwandu hwezvibooresa kuti zvizadzise zvidikanwi izvi. Kunyangwe ari ma-tri-cone bits, reverse circulation impactors uye bits, kana PDC bits, kupa zvemhando yepamusoro uye zvakavimbika zvekuchera maturusi zvakakosha pakuvaka kuvimbana uye kudyidzana kwenguva refu nemakambani emigodhi.

Muchidimbu, zviboorero zvemigodhi zvinoita basa rakakosha mukubudirira kwemabasa emigodhi. Kunzwisisa marudzi akasiyana ezviboorero, senge trione drill bits,reverse circulation impactors uye drill bits, uye PDC drill bits, zvakakosha kuti zvizadzise zvakasiyana-siyana zvinodiwa zvekuchera zveindasitiri yezvicherwa. Nekupa huwandu hwakakwana hwemabhiti ekuchera uye kugara uchifambirana nekufambira mberi muhunyanzvi hwekuchera, vatengesi vezvicherwa zvemigodhi vanogona kubatsira mukubudirira nekubudirira kwemabasa emigodhi pasi rese.
