Iinkcukacha zeMveliso

Iithegi zeMveliso

1. [Ukugrumba]
Isixhobo soomatshini esisebenzisa umngxuma ongaphantsi komhlaba ukuhambisa umthwalo woxinzelelo kwenye icandelo elingaphantsi komhlaba, ingakumbi xa elo candelo libambekile. Kukho iintlobo ezimbini eziphambili, iijari ze-hydraulic kunye neze-mechanical. Nangona uyilo lwazo lwahlukile kakhulu, ukusebenza kwazo kuyafana. Amandla agcinwa kwi-drillstring aze akhutshwe ngequbuliso yijari xa itsha. Lo mgaqo ufana nalowo wombazi osebenzisa ihamile. Amandla e-kinetic agcinwa kwihamile njengoko ishukunyiswa, kwaye akhutshwe ngequbuliso kwisikhonkwane kunye nebhodi xa ihamile ibetha isikhonkwane. Iijari zinokwenziwa ukuba zibethe phezulu, ezantsi, okanye zombini. Kwimeko yokubhoboza phezulu ngaphezulu kwendibano yomngxuma ongaphantsi ebambekileyo, umbhobho utsala kancinci kwi-drillstring kodwa i-BHA ayishukumi. Ekubeni umphezulu we-drillstring uhamba phezulu, oku kuthetha ukuba umbhobho ngokwawo uyasolula kwaye ugcina amandla. Xa iijari zifikelela kwindawo yazo yokudubula, ngequbuliso zivumela icandelo elinye lejari ukuba lihambe ngokuhambelana nomzuzwana, litsalwa ngokukhawuleza ngendlela efanayo naleyo isiphelo sentwasahlobo esoluliweyo sihamba ngayo xa sikhululwa. Emva kwe-intshi ezimbalwa zokuhamba, eli candelo lishukumayo lingena egxalabeni lentsimbi, linika umthwalo wokubetha. Ukongeza kwiinguqulelo zoomatshini kunye ne-hydraulic, iijari zihlelwa njengeejari zokubhola okanye iijari zokuloba. Ukusebenza kwezi ntlobo zimbini kuyafana, kwaye zombini zinika phantse ukubetha okufanayo kokubetha, kodwa ijari yokubhola yakhiwe ngendlela yokuba ikwazi ukumelana ngcono nomthwalo ojikelezayo kunye nokunyakaza okuhambelana nokubhola.
2. [Ukugqitywa kweMithombo]
Isixhobo somngxuma ongaphantsi komhlaba esisetyenziselwa ukubetha okanye umthwalo onzima kwindibano yezixhobo zomngxuma ongaphantsi komhlaba. Sisetyenziswa rhoqo kwimisebenzi yokuloba ukukhulula izinto ezibambekileyo, iijari ziyafumaneka ngobukhulu obahlukeneyo kunye namandla okuhambisa imithwalo yomthwalo ongaphantsi komhlaba phezulu okanye ezantsi. Ezinye izixhobo zomngxuma ongaphantsi komhlaba zisebenzisa iijari ukusebenzisa izixhobo ezinee-shear pins okanye ii-spring profiles kwindlela yazo yokusebenza.
3. [Ukulungiswa kweMithombo kunye nokungenelela]
Isixhobo somngxuma ongaphantsi esisetyenziselwa ukuhambisa amandla okubetha kwintambo yesixhobo, ngokuqhelekileyo ukusebenzisa izixhobo zomngxuma ongaphantsi okanye ukukhupha intambo yesixhobo ebambekileyo. Iingqayi zeendlela ezahlukeneyo kunye nemigaqo yokusebenza zihlala zifakwa kwi-slickline, ityhubhu ejijekileyo kunye neentambo zesixhobo sokusebenza. Iingqayi ezilula zomngxuma ongaphantsi ziquka indibano evumela ukuhamba ngokukhululekileyo ngaphakathi kwesixhobo ukuze kufumaneke amandla okubetha okwenzeka ekupheleni kokubetha. Iingqayi ezinkulu nezintsonkothileyo zetyhubhu ejijekileyo okanye iintambo zokusebenza ziquka indlela yokujika okanye yokudubula ethintela ingqayi ukuba isebenze de kube kufakwe uxinzelelo olufunekayo kwintambo, ngaloo ndlela kuphucula impembelelo ehanjiswayo. Iingqayi zenzelwe ukuphinda zisetyenziswe ngokulawulwa kwentambo kwaye ziyakwazi ukusebenza ngokuphindaphindiweyo okanye ukudubula ngaphambi kokuba zibuyiselwe equleni.
