Imbiza Yokubhoboza Emgodini Ophansi / Izimbiza Zokubhoboza (Ezomshini / Ezinomswakama)
1. [Ukubhoboza]
Idivayisi yomshini isebenzisa imbobo engezansi ukuletha umthwalo womthelela kwenye ingxenye yembobo ephansi, ikakhulukazi uma leyo ngxenye ibambekile. Kunezinhlobo ezimbili eziyinhloko, izimbiza ze-hydraulic nezemishini. Nakuba imiklamo yazo ihlukile kakhulu, ukusebenza kwazo kuyafana. Amandla agcinwa ku-drillstring futhi akhishwe ngokuzumayo yimbiza lapho idubula. Isimiso sifana nesombazi osebenzisa isando. Amandla e-kinetic agcinwa ku-hammer njengoba eshukunyiswa, futhi akhishwe ngokuzumayo ezipikilini nasebhodini lapho isando sishaya isipikili. Izimbiza zingaklanywa ukuthi zishaye phezulu, phansi, noma kokubili. Endabeni yokubhoboza phezulu ngaphezu kwenhlangano yembobo ephansi ebambekile, umshini wokubhoboza udonsa kancane ku-drillstring kodwa i-BHA ayinyakazi. Njengoba ingxenye ephezulu ye-drillstring inyuka, lokhu kusho ukuthi i-drillstring ngokwayo iyanwebeka futhi igcina amandla. Lapho izimbiza zifika endaweni yazo yokudubula, ngokuzumayo zivumela ingxenye eyodwa yembiza ukuthi ihambe ngokuhambisana nomzuzwana, idonswa ngokushesha ngendlela efanayo naleyo enye ingxenye yentwasahlobo eyeluliwe ehamba ngayo lapho ikhululwa. Ngemva kokunyakaza okungamasentimitha ambalwa, le ngxenye ehambayo ishaya ihlombe lensimbi, inikeze umthwalo wokushaya. Ngaphezu kwezinhlobo zemishini kanye ne-hydraulic, amabhodlela ahlukaniswa njengezimbiza zokubhoboza noma amabhodlela okudoba. Ukusebenza kwalezi zinhlobo ezimbili kuyafana, futhi zombili ziletha cishe ukushaya okufanayo kokushaya, kodwa ibhodlela lokubhoboza lakhiwe ngendlela yokuthi lingakwazi ukumelana kangcono nomthwalo ojikelezayo kanye nokudlidliza okuhambisana nokubhoboza.
2. [Ukuqedwa Kwemithombo]
Ithuluzi lokudonsa phansi elisetshenziselwa ukushaya kanzima noma umthwalo wokushaya endaweni yokudonsa phansi. Ngokuvamile lisetshenziswa emisebenzini yokudoba ukuze kukhululwe izinto ezinamathele, amabhodlela atholakala ngobukhulu obuhlukahlukene kanye namakhono okuletha imithwalo yokushaya phezulu noma phansi. Amanye amabhodlela amathuluzi abushelelezi asebenzisa amabhodlela ukuze asebenzise amathuluzi aqukethe izikhonkwane zokugunda noma amaphrofayili esiphethu ngendlela yawo yokusebenza.
3. [Ukusebenza Komthombo Nokungenelela]
Ithuluzi lokudonsa phansi elisetshenziselwa ukuletha amandla okushaya entanjeni yamathuluzi, ngokuvamile ukusebenzisa amathuluzi okudonsa phansi noma ukukhipha intambo yamathuluzi enamathele. Amabhodlela emiklamo ehlukene kanye nezimiso zokusebenza avame ukufakwa ezintanjeni zamathuluzi ezigoqekile, ezigoqekile kanye nezintambo zamathuluzi okusebenza. Amabhodlela alula ahlanganisa ukuhlanganiswa okuvumela ukuhamba kwamahhala ngaphakathi kwethuluzi ukuze kutholakale umfutho wokushaya okwenzeka ekupheleni kokushaya. Amabhodlela amakhulu, ayinkimbinkimbi kakhulu ezintambo ezigoqekile noma zokusebenzisa ahlanganisa indlela yokuhamba noma yokudubula evimbela ibhodlela ukuthi lisebenze kuze kube yilapho ukucindezeleka okufunwayo kufakwa entanjeni, ngaleyo ndlela kuthuthukisa ukushaya okulethwayo. Amabhodlela aklanyelwe ukusethwa kabusha ngokuphathwa kwentambo okulula futhi ayakwazi ukusebenza ngokuphindaphindiwe noma ukudubula ngaphambi kokuba atholakale emthonjeni.
