Izinto eziSisiseko zokuBonwa kweReverse Circulation
Ukugrumba okuthe tyaba akuyonto intsha. Abantu bomba amaqula kwiminyaka engaphezu kwama-8,000 eyadlulayo ukuze bafumane amanzi angaphantsi komhlaba kwiindawo ezishushu nezomileyo, hayi nje ngamasuntswana ePDC kunye neenjini zodaka njengoko sisenza namhlanje.
Zininzi izinto ekufuneka uziqwalasele xa ukhetha indlela yokomba. Le ngxelo iyinyani ngakumbi xa usombela ukuhlola okanye ukulawula ibakala. Uninzi lweekontraka kunye neenjineli zepetroleum zihlala zikhetha ukubuyisela umva ukujikeleza ngenxa yokuba kunika inzuzo eninzi kunezinye iindlela zokomba.
Phambi kokuqaqambisa izibonelelo zokomba ojikelezayo, makhe sichaze ukuba yintoni na yomfanekiso ocacileyo.
Yintoni iReverse Circulation Drilling?
Reverse circulation drilling yindlela yokomba esetyenziswayo umva ukujikelezisa amasuntswana ePDC, kunye neentonga ezineendonga eziphindwe kabini ukufezekisa ukubhola kunye nokuqokelela isampuli. Udonga lwangaphandle lunemibhobho yangaphakathi evumela ukuba i-cuttings idluliselwe kumphezulu njengoko inkqubo yokugaya iqhubeka.
Ukujikeleziswa okubuyela umva kusavumela ukuncamatheliswa kwezivula-mingxuma kodwa kuyahluka ekugrunjweni kwedayimani kuba kuqokelela ukusika amatye endaweni yombindi wamatye. I-drill isebenzisa amasuntswana akhethekileyo okujikeleza okujikelezayo aqhutywa yipiston ebuyisela umoya okanye isando.
La masuntswana e-reverse drill enziwe nge-tungsten, intsimbi, okanye indibaniselwano yezi zimbini kuba zomelele ngokwaneleyo ukuba zinqumle kwaye zityumze iliwa eliqine kakhulu. Ngeentshukumo zayo zepiston, isando sinokususa ilitye elityumkileyo, elithi ke lihanjiswe phezulu ngomoya oxinanisiweyo. Umoya uvuthuza phantsi kwi-annulus. Oku kudala utshintsho kuxinzelelo olubangela ukujikeleza okujikelezayo, okuhambisa ukusika kwi-tube.
Ukugrumba okujikelezayo okubuyela umva kulungile xa kusenziwa isampulu yamatye angaphantsi komhlaba ukuze kuhlalutywe istratification kunye nesiseko seenjongo zobunjineli.
Ngoku uyazi ukuba yintoni na, makhe sijonge ezinye zezibonelelo zokujikeleza ukujikeleza.
Iluncedo ekuFumaneni iisampulu ezingangcolisekanga
Ukugrumba okujikelezayo kuphelisa nakuphi na ukungcoliseka okunqamlezileyo kokusikwa kwamatye xa kukhutshelwa phezulu, njengoko iziqwenga zihamba ngetyhubhu engaphakathi evalelweyo enombombo omnye kuphela kumphezulu apho isampulu iqokelelwa khona. Ngoko ke, unako ukuqokelela inani elikhulu leesampuli ezikumgangatho ophezulu ukuze uhlalutye.
Amazinga oNgenelo angakholelekiyo
Amasuntswana akhethekileyo okujikeleza okujikelezayo anamandla ngakumbi kunamasuntswana aqhelekileyo okugqiba ngenxa yeengcebiso ezidibeneyo ze-tungsten-steel. I-reverse circulation drills isebenza ngesantya esikhawulezayo kwaye iphinda ifumane ukusika ngexesha lerekhodi. Isantya apho izisika zigqithiselwa khona zibuyele kumphezulu zinokukroba ngokulula kwiimitha ezingama-250 ngomzuzwana.
Ukuguquguquka kwiimeko ezimbi
Ukuguqula ukujikeleza kokujikeleza akuyona inkqubo enzima kwaye ayifuni amanzi amaninzi. Olu phawu lwenza ukuba ukombiwa okujikelezayo kubuyele umva kulunge nakwiindawo apho amanzi anqabe khona njengeendawo ezisemaphandleni okanye ezomileyo.
Ngexabiso eliphantsi
I-reverse circulation drilling ineendleko kakhulu, ngakumbi xa kuthelekiswa nokugrumba idayimani. Akunjalo nje ngenxa yeendleko ezincitshisiweyo zokusebenza, kodwa nangenxa yexesha elifutshane elithathayo ukugqiba ukugaya. Lilonke, ukombiwa kwe-reverse circulation kungabiza ukuya kuma-40% ngaphantsi kunokomba okuqhelekileyo. Ukuba usomba kwiindawo ezinomhlaba orhabaxa, ukusebenza kakuhle kweendleko kunokuphinda kabini.
UReverse Circulation for Grade Control
Umgangatho weesampulu ezifunyenweyo ubaluleke kakhulu kuyo nayiphi na inkqubo yokuhlola ukwenza ucwangciso oluchanekileyo lomgodi okanye ukubeka iziqhushumbisi. Ulawulo lwamabakala lulo olusetyenziselwa ukuchaza iibhloko kunye namabakala e-ore. Ukubuyisela umqolo ukujikeleza kulungile kulawulo lwebakala kuba:
- Ifuna ukuphathwa okuncinci kunezinye iindlela
- Iisampulu ezifunyenweyo azikho nakuphi na ungcoliseko
- Ixesha lokujika ngokukhawuleza
- Iisampulu ezifunyenweyo zinokuthathwa ngqo kwilebhu ukuze zihlalutywe
Eyona nto ibalulekileyo kuwo nawuphi na umsebenzi wokugrumba ojikelezayo kukusikwa kwesampulu. Iindlela ezininzi zingasetyenziselwa ukubuyiswa kwesampulu, kodwa eyona njongo iphambili kukufumana iisampulu ezisemgangathweni kangangoko ngexeshana elifutshane.
Ukuba ufuna naziphi na iinkonzo zokomba ezijikelezayo, khumbula ukufuna kuphela iingcali ezinelayisenisi eziyaziyo indlela yazo malunga ne-reverse circulation drill kwaye zizazi kakuhle iinkqubo ezahlukeneyo. Cela ukuba basebenzise kuphela umgangatho ophezulu oqinisekisiweyoumva ukujikelezisa amasuntswana ePDCukunqanda nakuphi na ukulibaziseka okubangelwa ngamasuntswana e-drill ephukile. Okokugqibela, soloko uqinisekisa ukuba inkqubo yokomba ihambelana nemigangatho ebekiweyo yokusingqongileyo.
