Lapho i-rotary drilling rig isebenza, kuhlale kunezinsalela phansi embobeni, okuyisici esingenakugwenywa se-rotary drilling rig.Pho kungani inenhlabathi phansi embobeni?Isizathu esiyinhloko ukuthi inqubo yokwakhiwa kwayo ihlukile.I-Rotary drilling rig ithatha indlela yokumba udaka olungajikelezi, futhi i-slag yokumba ayikwazi ukuthuthwa phansi ngokujikeleza kodaka ukuze ihlale phansi.
Lokhu okulandelayo yizizathu eziyinhloko zokuvela kwe-sediment:
1.Izinsalela phakathi kwamazinyo ebhakede omshini wokumba ojikelezayo kanye nesembozo sangaphansi sebhakede lokumba
2.Amazinyo ezinsimbi zokumba ama-rotary amancane, ngakho-ke i-sediment phakathi kwamazinyo ayinakugwenywa;
I-3.Ikhava engezansi yethuluzi lokubhoboza ayivalwanga ngokuqinile;
4.Inhlabathi enqunywe emaphethelweni angaphandle ebhakede lokumba elijikelezayo ayikwazi ukungena emlonyeni we-cylinder ngenxa yephansi eliphansi lomgodi futhi lihlala emaphethelweni angaphansi komgodi;
5.Lapho kubhola isihlabathi sodaka kanye nokwakheka kwe-flow-plastic, i-slag yokubhoboza ebhakedeni lokubhoboza iyalahleka phakathi nenqubo yokuphakamisa, futhi ngezinye izikhathi ngisho nayo yonke ilahlekile emgodini we-borehole;
6.I-stroke ebuyayo yebhakede lokubhoboza inkulu kakhulu, umthwalo ugcwele kakhulu, futhi udaka lukhama luphume emgodini wokudonsa amanzi wekhava engaphezulu.
Ngokwezinga likazwelonke, ukujiya okuhlosiwe kwe-sediment phansi kwembobo yenqwaba yezingxabano kanye nenqwaba ephethe isiphetho ayikho ngaphezu kuka-100mm futhi angabi ngaphezu kuka-50mm, ngokulandelanayo.
Okungenhla yizizathu zokuvela kwezinsalela ekwakhekeni kwembobo yezinsimbi zokumba ezincane ezijikelezayo ezifingqiwe yiGookma.Nakuba lokhu kuyisici esingenakugwenywa sezinsimbi zokumba ezincane ezijikelezayo, izinsimbi zokumba ezijikelezayo zisewumshini ofaneleka kakhulu wokumba nokunqwabelanisa kulesi sigaba.
Ngemuva kokuthi i-rotary drilling rig ibhoboze umgodi, kufanele sihlanze umgodi, ukuze i-sediment engaphansi komgodi isuswe.
