Umahluko phakathi koMbhobho wokuDrila kunye neKhola yeDrill

Imibhobho yokomba kunye neekhola zokomba zizixhobo ezibalulekileyo kwishishini leoli. Eli nqaku liza kwazisa umahluko phakathi kwezi mveliso zimbini.

Drill iiKhola

I-collars ye-Drill ibekwe phantsi komtya we-drill kwaye iyona nxalenye ephambili yendibano ye-bottom hole (BHA). Iimpawu zabo eziphambili ziindonga zabo ezingqingqwa (ngokubanzi yi-38-53mm, ephindwe ka-4-6 ngaphezu kweendonga zemibhobho yokubhobhoza), ebonelela ngobunzima obuninzi kunye nokuqina. Ukuququzelela imisebenzi yokomba, ukuphakamisa iigrooves kunye ne-grooves yokutyibilika kunokwenziwa ngoomatshini kumphezulu ongaphandle wemisonto yangaphakathi ye-drill collar.

Imibhobho yoBomba

Iibhobho zokubhobhoza ziyimibhobho yentsimbi eneziphelo ezinentambo, ezisetyenziselwa ukudibanisa izixhobo ezingaphezulu kwendawo yokubhoboza kunye nezixhobo zokubhoboza okanye ukudibanisa umngxuma ongezantsi phantsi komthombo. Iinjongo zemibhobho yokomba kukuthutha udaka lokugrumba ukuya kwindawo yokomba kunye nokusebenza nentwana yokomba ukunyusa, ukwehlisa, okanye ukujikelezisa indibano yomngxuma ongezantsi. Imibhobho yokubhobhoza kufuneka imelane noxinzelelo olukhulu lwangaphakathi nangaphandle, ukushukuma, ukugoba, kunye nokungcangcazela. Ngexesha lokukhutshwa kweoli kunye negesi kunye nokucocwa, iipayipi zokubhoboza zingaphinda zisetyenziswe ngamaxesha amaninzi. Imibhobho yokomba yahlulahlulwe ngokwemibhobho yesikwere, imibhobho yokomba eqhelekileyo, kunye nemibhobho yokomba enzima.

Iindima ezahlukeneyo kwi-Oli kunye ne-Gesi Extraction
Ezi zixhobo zimbini zisebenza ngeenjongo ezahlukeneyo kwi-oyile kunye ne-gas extraction. Iikhola zokubhoboza ziyimibhobho yentsimbi enodonga olungqindilili esetyenziswa ikakhulu ukongeza ubunzima kwintambo yokomba, ebonelela ngoxinzelelo olukhulu lokomba kunye nokuthintela ukutenxa kwiqula. Imibhobho yokomba, kwelinye icala, yimibhobho yentsimbi enodonga olucekethekileyo esetyenziselwa ukuhambisa itorque kunye nolwelo lokomba ukuze kube lula ukujikeleza kunye nokugrunjwa kwentwana yokomba.

Isishwankathelo, iikhola zokugaya, kunye nobunzima obuninzi kunye nokuqina, zibonelela ngobunzima obongezelelweyo kunye nokuzinza kwintambo yokubhoboza, ngelixa iipayipi zokubhoboza zinoxanduva lokuhambisa amandla omatshini kunye nokuthutha udaka lokugaya. Ezi zixhobo zimbini zisebenza kunye ukuqinisekisa ukusebenza kakuhle kwemisebenzi yokomba.
