Ehlabathini lokomba, i-evolution yePDC (i-polycrystalline diamond compact) yabasiki benguqu iye yatshintsha umdlalo kwishishini leoli kunye negesi. Ukutyhubela iminyaka, abasiki bePDC baye bafumana utshintsho olubalulekileyo kuyilo kunye nokusebenza, ukuphucula ukusebenza kwabo kunye nokwandisa ubomi babo.
Ekuqaleni, abasiki bePDC babeyilelwe ukubonelela ngenye indlela ehlala ixesha elide kunye nesebenzayo ekufakeni i-tungsten carbide yendabuko. Baqala ukwaziswa ngo-1970 kwaye ngokukhawuleza bafumana ukuthandwa ngenxa yokukwazi ukumelana nobushushu obuphezulu kunye noxinzelelo kwizicelo zokomba olunzulu. Nangona kunjalo, abasiki be-PDC bokuqala babethintelwe yindalo yabo ebuthathaka kwaye babeqhelene nokuqhekeka kunye nokwaphuka.
Njengoko itekhnoloji iqhubela phambili, abavelisi baqala ukuzama izixhobo ezintsha kunye noyilo lokuphucula ukusebenza kwabasiki bePDC. Olunye lolona phuhliso lubalulekileyo kukuqaliswa kwee-thermally stable polycrystalline diamond (TSP) cutters. Aba basiki babonise umaleko wedayimani owomeleleyo kwaye banokumelana namaqondo obushushu aphezulu kunye noxinzelelo kunezisiki zePDC zemveli.
Enye impumelelo enkulu kwitekhnoloji ye-PDC yokusika yaba kukuqaliswa kwee-hybrid cutters. Aba basiki badibanisa ukuqina kwePDC kunye nokuqina kwe-tungsten carbide ukwenza isixhobo sokusika esinokusingatha nezona zicelo zinzima kakhulu.
Kwiminyaka yakutshanje, ukuqhubela phambili kubuchule bokwenza kuvumele ukwenziwa kweejometri ezintsonkothileyo kubasiki bePDC. Oku kuye kwakhokelela ekuphuhlisweni kwee-cuttings ezikhethekileyo ezenzelwe izicelo ezithile zokugaya, ezifana nokubhola kwesikhokelo kunye noxinzelelo oluphezulu / lobushushu obuphezulu.
Inguquko yabasiki bePDC ibenempembelelo enkulu kwishishini leoli negesi. Ngokukwazi kwabo ukujamelana neemeko ezigqithisileyo kwaye zihlala ixesha elide kunezixhobo zokusika zendabuko, abasiki bePDC baye bandisa ukusebenza kakuhle kunye nokunciphisa ixesha lokunciphisa. Njengoko itekhnoloji yokugrumba iqhubela phambili, kusenokwenzeka ukuba siza kubona uphuhliso olungakumbi kuyilo kunye nokusebenza komsiki wePDC.
Ukuqukumbela, abasiki bePDC bahambe umgama omde ukusukela oko baziswa ngoo-1970. Ukususela kwiintsuku zabo zangaphambili njengenye indlela ehlala ixesha elide yokufaka i-tungsten carbide, kuphuhliso lwabasiki abakhethekileyo abayilelwe izicelo ezithile zokomba, ukuvela kwee-PDC cutters akuzange kube yinto emfutshane ephawulekayo. Njengoko ishishini leoli negesi liqhubeka nokuvela, abasiki bePDC ngokungathandabuzekiyo baya kudlala indima ebalulekileyo ekuqhubeni ukusebenza kakuhle kunye nemveliso kwimisebenzi yokomba.
