Ekukhuleni okuqhubekayo kwemfuno yobutyebi behlabathi, izixhobo zemigodi ezisebenzayo nezizinzileyo zibalulekile ekuqinisekiseni ukunikezelwa kwamandla nezimbiwa. Abasiki be-polycrystalline diamond compact (PDC), kunye nokusebenza kwabo okuphezulu, ngokuthe ngcembe batshintshela abasiki bemveli be-carbide njengenxalenye ephambili ekutsalweni kwezixhobo. Ixabiso labo elingundoqo lisemacaleni amathathu aphambili: impumelelo yetekhnoloji, ukulungelelaniswa okuthe ngqo kwisicelo, kunye nobuchule bokuqamba izinto ezintsha.

Ukusuka kumbono wobugcisa, abasiki bePDC baphumelele umtsi we-quantum kubulukhuni kunye nokumelana nokunxiba. Idityaniswe phantsi kobushushu obuphezulu kunye noxinzelelo oluphezulu oluvela kwidayimane yomgubo omncinci kunye ne-carbide substrate, bafumana ilifa lobulukhuni obuphezulu bedayimane (ngaphezu kwe-HV10,000) ngelixa begcina ukuqina kwempembelelo ye-carbide. Oku kusombulula ingxaki ejongene nabasiki bemveli: ubunzima obuphezulu bukhokelela kubunzima, ngelixa ubunzima obuphezulu bukhokelela ekunxibeni. Kwimigodi ye-deep-shaft, i-PDC cutters, esebenza kwiindlela zamatye anzima njengegranite kunye ne-basalt, zibonisa izinga lokunxiba elikwisinye sesihlanu kuphela se-carbide cutters, ukwandisa ubomi babo benkonzo ngamaxesha angama-3-5. Oku kunciphisa kakhulu ukuphindaphindeka kokutshintshwa kwamacandelo ngaphantsi komhlaba kwaye kuthomalalise umngcipheko wokuphazamiseka kwemigodi. Ngokumalunga nokuguquguquka, ukuguquguquka kwabasiki bePDC kuhlangabezana neemfuno ezahlukeneyo zokutsalwa kwezixhobo. Kwi-oyile kunye negesi yokwembiwa, iindawo zabo ezibukhali ezibukhali zityumza ngokukhawuleza ukubunjwa kwamatye. Iiprofayili zamazinyo ezenzelwe wena (ezifana neemilo ze-wedge kunye necephe) zilungelelanisa iindlela ezahlukeneyo zomthombo wamazinyo, ukwandisa ukusebenza kakuhle kokugrumba kwiqula elithe tye nakwalathe cala ngaphezulu kwe-40%. Emigodini yamalahle, abasiki bePDC abaxhathise impembelelo bamelana nempembelelo enkulu yokubandakanywa komthungo wamalahle, ukuthintela ukwaphuka kwamazinyo kunye nokuqinisekisa ukusebenza okuqhubekayo kwezixhobo zemigodi ezisebenza ngokupheleleyo. Kwimigodi yesinyithi, abasiki bePDC abaneengubo ezikwaziyo ukumelana nomhlwa bayaxhathisa ukhukuliseko olusuka kumanzi emigodi aneasidi, oko kubenza bafaneleke kuyo yomibini imingxuma evulekileyo kunye nemigodi engaphantsi komhlaba kwiindawo ezintsonkothileyo zejoloji.

Ngokwembono yoshishino, abasiki bePDC baye banegalelo ngokuthe ngqo ekunciphiseni iindleko kunye nokuphucula ukusebenza kakuhle ekutsalweni kwezixhobo. Kwelinye icala, ubomi babo obude bunciphisa iindleko zokuthenga nokutshintsha izinto ezisetyenziswayo. Ngokomzekelo, kwi-oyile yokugaya, iindleko zabasiki kwiqula ngalinye zingancitshiswa ngama-20% -30%. Ngaphaya koko, ukusebenza kwabo okusebenzayo kokusika kunciphisa umjikelo wemigodi. Umzekelo, emva kokwamkela abasiki bePDC, umgodi omkhulu wamalahle wonyuse umfanekiso wemihla ngemihla womchebi ukusuka kwi-80 yeemitha ukuya kwi-120 yeemitha, ukwandisa umthamo wonyaka wemveliso nge-15%. Ngapha koko, iipropathi zokunxiba eziphantsi zabasiki bePDC zinciphisa ukuveliswa kokusikwa kunye nokwenza lula imizamo yokucoca i-downhole, ukuphucula ngokungathanga ngqo ukhuseleko lwemigodi.

Njengoko ukukhutshwa kwezixhobo kuqhubela phambili nzulu kwaye kulwakhiwo oluntsonkothileyo, indaleko yetekhnoloji yabasiki bePDC iyaqhubeka nokukhawuleza. Kwixesha elizayo, ngokuphucula ukumelana nobushushu obuphezulu ngokusebenzisa itekhnoloji yokugquma i-nano kunye nokwandisa ubume be-cutter ngokuprinta kwe-3D, abasiki bePDC baya kuphinda boyise imiqobo yokusebenza, babonelele ngenkxaso eyomeleleyo kuphuhliso lwemithombo enzima ukukhupha njengerhasi ye-shale kunye neeminerali ezinzulu zolwandle, kunye nokudibanisa ngakumbi indawo yabo ephambili ekutsalweni kwezixhobo.
