Ukuqonda iSiseko sokuLawula kakuhle
Kwishishini leoli kunye negesi,ulawulo kakuhle yinkalo ebalulekileyo yokuqinisekisa ukhuseleko kunye nokusebenza kakuhle kwemisebenzi yokomba. Kodwa ulawulo olulungileyo lusebenza njani kwaye kutheni lubaluleke kangaka? Kule bhlog, siza kungena kwiziseko zolawulo lwequla kwaye sixoxe ngokubaluleka kwayo kwihlabathi le-oyile negesi.
Ukulawulwa kakuhle yinkqubo yokugcina ingqibelelo ye-wellbore kunye nokuthintela ukukhutshwa okungalawulwayo kokubunjwa kwamanzi (okufana neoli, igesi yendalo, okanye amanzi) ngexesha lemisebenzi yokomba. Oku kuphunyezwa ngokudityaniswa kolawulo lobunjineli, iinkqubo zokubeka iliso kunye nobuchule babasebenzi abombayo.
Enye yezinto eziphambili zolawulo lomthombo yinkqubo yokuthintela ukuvuthela (BOP). Esi sixhobo sibalulekileyo siyilelwe ukutywina iqula kunye nokuthintela ukukhutshwa okungalawulekiyo kolwelo ngexesha lokukhaba okanye ukuvuthela. Inkqubo ye-BOP idla ngokuqulatha isitakhi seevalvu kunye namasango anokuthi avulwe ukuvala ukuhamba kolwelo ngaphakathi kwequla.
Ukongeza kwinkqubo yokuthintela ukuvuthela,ulawulo kakuhle kubandakanya ukusetyenziswa kolwelo lokomba, olukwabizwa ngokuba ludaka, ukugcina uxinzelelo kunye nozinzo ngaphakathi komthombo. Ngokujikelezisa ulwelo lokugaya ecaleni kombhobho wokugaya kwaye ubuyele kwi-annulus, abaqhubi be-drilling banokulawula uxinzelelo olwenziwa ngokubunjwa kunye nokuthintela ulwelo olwenziwayo ukuba lungene kwiqula.
Ukongeza, ulawulo lomthombo luxhomekeke kubuchwephesha babaqhubi, kubandakanya abombi, iinjineli zodaka kunye.ulawulo kakuhle iingcali, abaqeqeshelwe ukubeka esweni kwaye baphendule kutshintsho kuxinzelelo lwe-wellbore kunye neempawu zolwelo. Ezi ngcali zinoxanduva lokuqhuba uqheliso lolawulo lwamaqula rhoqo, ukugcina izixhobo zokusebenza kunye nokuphumeza izicwangciso zokuquleka kwimeko kaxakeka.
Ukubaluleka kolawulo lwequla akunakubaxwa, njengoko iziphumo zokuvuthuza okanye ukusilela kulawulo lwequla kunokuba yintlekele. Ayibangeli nje umonakalo wokusingqongileyo kunye nelahleko yezinto ezixabisekileyo, ikwabeka imingcipheko ebalulekileyo kukhuseleko lwabantu kunye noluntu olungqongileyo. Ngoko ke, ukuphumeza imilinganiselo yolawulo lomthombo owomeleleyo kubalulekile ekukhuseleniimfezeko imisebenzi yokomba.
Isishwankathelo, ulawulo lomthombo luyinkalo esisiseko yokusebenza kokomba kwishishini leoli negesi. Ngokudibanisa ulawulo lobunjineli, iinkqubo zokubeka iliso kunye nobuchule be-driller, ukulawulwa kakuhle kwenzelwe ukuthintela ukukhutshwa okungalawulwayo kokubunjwa kwamanzi kunye nokugcina ingqibelelo ye-wellbore. Ukuqonda iziseko zolawulo lomthombo kunye nokubaluleka kwayo kubalulekile ekuqinisekiseni ukhuseleko nokusebenza kakuhle kwemisebenzi yokomba.
