IsiKhokelo esiGqibeleleyo kwiintlobo zoMlomo wePDC kunye nezicelo

Kwimimandla efana nokugrumba i-oyile kunye nokuphononongwa kwe-geological, imilomo ye-PDC (i-Polycrystalline Diamond Compact) ibe yinxalenye ebalulekileyo yokuqinisekisa ukusebenza kakuhle kunye nomgangatho, ngenxa yokumelana nokunxiba okugqwesileyo, ukumelana nobushushu obuphezulu, kunye nokumelana nefuthe. Baqaphela imisebenzi efana nokuqhekezwa kwamatye, ukucocwa kwamatye, kunye nokupholisa kancinci ngoxinzelelo oluphezulu lwejethi. Iindidi ezahlukeneyo zemilomo yePDC zilungele iimeko ezahlukeneyo zokusebenza. Ezi zilandelayo zineenkcukacha zokuhlelwa kwazo kunye nezicelo ezihambelanayo.

1. Ukuhlelwa ngokoYilo lweZakhiwo

Imilomo yePDC yahlulwe ikakhulu yaba ziindidi ezintathu ezisekelwe kuyilo lwesakhiwo: uhlobo lwesitofu ngokuthe ngqo, uhlobo olujingizayo, kunye nodidi lomxube.

Imilomo yePDC yokutofa ngokuthe ngqo: Yamkela isakhiwo setshaneli ethe tye. Ukuhamba kwejethi kugxininiswe ngamandla anamandla, anokuthi aphule ngokukhawuleza ukubunjwa kwamatye aqinile. Zisetyenziswa kakhulu kwimisebenzi yokomba amatye aqinileyo kumaqula anzulu kunye namaqula anzulu kakhulu, ngokufanelekileyo aphucula ukusebenza kakuhle kokuqhekeza amatye kunye nokunciphisa ukunxitywa kwebit drill bit.

Imilomo ye-Swirling PDC: Ixhotyiswe ngesakhiwo esikhokelayo esijikelezayo ngaphakathi. Xa ulwelo lutofwa, ibala lokuhamba elijikelezayo lenziwa, elinganyusi nje kuphela isakhono sokucoca ilitye elisikwa emazantsi equla kodwa likwanciphisa ukuguquguquka koxinzelelo ezantsi. Zifanelekele iimeko zokubhoboza kwiifom eziguquguqukayo ngokulula okanye ukubunjwa okunomxholo ophezulu wesanti, ukuthintela ukusika kwamatye ekuqokeleleni kunye nokuchaphazela inkqubela phambili yokugaya.

Imilomo ye-Hybrid PDC: Dibanisa izibonelelo zezi ntlobo zimbini zingasentla, kunye nefuthe lempembelelo ye-injection ngokuthe ngqo kunye nefuthe lokucoca elijikelezayo. Basebenza ngokubonakalayo kwimisebenzi yokomba ngeendlela ezintsonkothileyo, ezifana nokugrumba okuthe tye kuphuhliso lwerhasi ye-shale. Bangakwazi ukulungelelanisa iimfuno zokuqhekezwa kwamatye kunye nokucoca amatye, ukuphucula ukuzinza ngokubanzi kokomba.

2. Ukuhlelwa ngokweSicelo esiSebenzayo

Ngokwesicelo esisebenzayo, imilomo yePDC inokohlulwa ibe ezo zokuqhekeza amatye, ukucocwa kwamatye, kunye nokupholisa.

Imilomo yePDC yokuqhekezwa kwamatye: Idla ngokuyilwa ngomgangatho omkhulu kunye nesantya sokuhamba okuphezulu. Baqhekeza ukumila kwamatye ngoxinzelelo oluphezulu lwempembelelo yolwelo kwaye bafanele ukugrunjwa kumatye aqinileyo kunye namatye axineneyo.

Imilomo yePDC yokucoca amatye: Gxininisa ekwandiseni ukuhanjiswa kwebala lokuqukuqela ukuqinisekisa ukuba ukusika amatye kuthuthwa emhlabeni ngexesha elifanelekileyo. Ngokuqhelekileyo zisetyenziselwa ukwakheka okuthambileyo okanye amacandelo alungele ukukala.

Imilomo yePDC yokupholisa: Ngoyilo olufanelekileyo lomjelo wokuqukuqela, bahambisa ngokuchanekileyo ulwelo olupholisa kwindawo esebenzayo yesuntswana le-drill, ukunciphisa ubushushu obusebenzayo be-PDC compact kunye nokwandisa ubomi benkonzo ye bit drill. Zisetyenziswa kakhulu kumaqula anzulu obushushu obuphezulu okanye kwimisebenzi yokugrumba eqhubekayo yexesha elide.

3. Ukuhlelwa ngokwezinto eziphathekayo

Ukongeza, ngokusekwe kumahluko wezinto ezibonakalayo, imilomo yePDC inokwahlulwa ibe ziindidi ezimbini:izinto PDC ecocekileyo kunye imathiriyeli ehlanganisiweyo yePDC kunye nekhabhide enesamente.

Imilomo yemathiriyeli yePDC ecocekileyo:Yiba nobunzima obuphezulu ngokugqithisileyo kunye nokunganyangeki ngokufanelekileyo, ngokufanelekileyo kwiindawo zokomba ezintsonkothileyo.

Imilomo yemathiriyeli ehlanganisiweyo:Ngelixa beqinisekisa ukumelana nokunxiba, banciphisa iindleko zemveliso kwaye bafanelekile kwiimeko zokusebenza zokomba eziqhelekileyo.

Kwizicelo ezisebenzayo, kuyimfuneko ukukhetha ngokufanelekileyo uhlobo lomlomo wePDC ngokusekwe kwizinto ezinjengobunzulu bokomba, ubulukhuni bokubumba, kunye nohlobo lolwelo ukunyusa ukusebenza kakuhle kokomba kunye nokwandisa iindleko. Njengoko uphononongo lwe-oyile kunye nophuhliso lusiya kulwakhiwo olunzulu noluntsonkothileyo, uyilo lwemilomo ye-PDC luhlala lusenziwa izinto ezintsha. Kwixesha elizayo, baya kuphuhlisa kwicala lokunganyangeki, basebenze ngakumbi, kwaye bafaneleke ngakumbi kwiimeko ezininzi zokusebenza, ukubonelela ngenkxaso yobugcisa obuqinileyo kuphuhliso lwe-oyile kunye negesi.
