Indlela yokugrumba yokomba kwimingxuma enzulu yokomba kunye neengxaki ezifuna ingqwalasela ekusebenzeni
siyakuqonda ukubaluleka kweendlela zokomba kunye nezilumkiso zokusebenza kwi-drilling enzulu. Ukubunjwa kobume bomhlaba okwahlukileyo kuneempawu ezahlukileyo, ngoko ke imisebenzi yokugrumba kufuneka iqhutywe ngokweempawu zesakhiwo sequla.
Xa kusetyenzwa kwiindawo ezineempazamo,ukuwa, ukuqhekeka, kunye nokudityaniswa kokwakheka kunokukhokelela kwimiba eyahlukeneyo efana namazinga aphezulu okuhamba, i-voids encinci, kunye nelahleko ebalulekileyo yoxinzelelo lwempompo, ngaloo ndlela ithintela inkqubela phambili yokomba. Ukongezelela, kukho imingcipheko yokungahambi kakuhle okanye ukuphuka ngexesha lokukhutshwa kunye nokufakwa kwee-ultra-deep casings.
Ukujongana nale mingeni,siphumeze imilinganiselo emininzi ngexesha lemisebenzi yokwemba. Okokuqala, sikhetha amasuntswana okomba amakhulu kwaye sisebenzise izixhobo zokuphinda sisebenzise izixhobo zokuphinda siphucule ukusebenza kakuhle kunye nokuzinza. Kuyo yonke inkqubo yokugrumba, sihlala sihlengahlengisa ukusebenza kolwelo olugungxulwayo kwaye sihlambe izihlandlo ezininzi ukugcina ukucoceka kwequla. Ngaphaya koko, ukuveyishwa okucokisekileyo kuqhutywa phambi nasemva komjikelo ngamnye wokomba ukuze kuthintelwe iimpazamo ngexesha lokukhutshwa okanye ukungaphumeleli kancinci, kwaye imilinganiselo echanekileyo yobude bentsalela kwirig ithathwa ukuqinisekisa ukuchaneka kwendawo.
Ngaphezu koko, sihlala siluphaphele uxinzelelo lwempompo, ukubuyiswa kwamanzi, izandi ezingaqhelekanga, kunye notshintsho kwimisinga yombane ngaphakathi kumngxuma wokutsala amanzi ukunciphisa imingcipheko yokutsha okanye yokwaphula ukomba. Ngenxa yokuxhathisa okubalulekileyo kokugrumba kumngxuma onzulu, sisebenzisa iindlela zobuchule bokuphakamisa isuntswana le-drill off the borehole, ngokuthe ngcembe sibandakanya i-clutch xa isantya sokujikeleza sisondela kwinqanaba elimiselweyo, kwaye ke ngokucothayo siqhubeke nokugrumba okuqhelekileyo ukuthintela ukonyuka kwetorque ngequbuliso. kunokukhokelela ekuqhekezeni intonga.
Ukuqukumbela, ukusetyenziswa kwemingxuma yokugrumba i-down-the-hole (i-DTH) iye yaphucula kakhulu ukusebenza kakuhle kokomba kunye nokunciphisa iindleko zeprojekthi kwiiprojekthi zokomba onzulu, igalelo elibalulekileyo kumandla kunye nokuhlola izimbiwa. Sizibophelele ekuqhubeni siphucula iinkqubo zethu zokomba, siphucula impumelelo yokusebenza, kunye nokuhambisa iimveliso neenkonzo ezithembekileyo nezisebenzayo kubathengi bethu.
