Umhlahlandlela Ophelele we-PDC Nozzle Izinhlobo Nezicelo

Emikhakheni efana nokumba uwoyela nokuhlola umhlaba, imibhobho ye-PDC (i-Polycrystalline Diamond Compact) isiphenduke izingxenye ezibalulekile eziqinisekisa ukusebenza kahle kokubhola kanye nekhwalithi, ngenxa yokumelana nokuguga okuhle kakhulu, ukumelana nezinga lokushisa eliphezulu, kanye nokumelana nomthelela. Babona imisebenzi efana nokuqhekeka kwamadwala, ukuhlanzwa kwamadwala, nokupholisa i-drill bit ngokusebenzisa uketshezi lwejethi olunomfutho ophezulu. Izinhlobo ezahlukene zemibhobho ye-PDC zifanele izimo zokusebenza ezihlukene. Imininingwane elandelayo ngezigaba zabo kanye nezicelo ezihambisanayo.

1. Ukuhlelwa Ngokuklama Kwesakhiwo

Ama-nozzle e-PDC ahlukaniswe kakhulu abe izinhlobo ezintathu ngokusekelwe ekwakhiweni kwesakhiwo: uhlobo lomjovo oqondile, uhlobo olujikelezayo, kanye nohlobo lwe-hybrid.

Imibhobho ye-PDC yomjovo oqondile: Yamukela isakhiwo seshaneli eqondile. Ukugeleza kwe-jet kugxilwe ngamandla anamandla anomthelela, anganqamula ngokushesha ukwakheka kwamadwala aqinile. Asetshenziswa kakhulu emisebenzini yokumba amatshe aqinile emithonjeni ejulile kanye nemithombo ejulile kakhulu, athuthukisa ngempumelelo ukusebenza kahle kokugqekeza amatshe kanye nokunciphisa ukuguga kwe-drill bit.

I-Swirling PDC nozzles: Ifakwe isakhiwo esijikelezayo esiqondisa ukugeleza ngaphakathi. Lapho uketshezi lujova, insimu yokugeleza ejikelezayo iyakhiwa, engagcini nje ngokuthuthukisa ikhono lokuhlanza le-rock cuttings ngaphansi komthombo kodwa futhi inciphisa ukuguquguquka kwengcindezi phansi. Zifanele izimo zokumba ekwakhekeni okugoqeka kalula noma ukwakheka okunenhlabathi ephezulu, ukuvimbela ukusikwa kwamadwala ekuqongeleleni futhi kuthinte inqubekelaphambili yokumba.

Imibhobho ye-Hybrid PDC: Hlanganisa izinzuzo zezinhlobo ezimbili ezingenhla, ngazo zombili amandla omthelela womjovo oqondile kanye nomphumela wokuhlanza ojikelezayo. Basebenza ngokugqamile emisebenzini yokumba ngezindlela eziyinkimbinkimbi, njengokumba umthombo ovundlile ekuthuthukisweni kwegesi ye-shale. Bangakwazi ukulinganisa izidingo zokuqhekeka kwamatshe kanye nokuhlanza amatshe, bathuthukise ukusimama kokumba jikelele.

2. Ukuhlelwa ngohlelo lokusebenza olusebenzayo

Ngokokusebenza okusebenzayo, imibhobho ye-PDC ingahlukaniswa ibe yilabo abaphula amatshe, ukuhlanzwa kwamatshe, nokupholisa.

Imibhobho ye-PDC yokuphuka kwamadwala: Ivamise ukudizayina ngezinga elikhulu nezinga lokugeleza okuphezulu. Aphula ukwakheka kwamadwala ngokusebenzisa uketshezi olunomfutho ophezulu futhi afanele ukubhola emadwaleni aqinile kanye namatshe aminyene.

Imibhobho ye-PDC yokuhlanza amadwala: Gxila ekuthuthukiseni ukusabalalisa kwenkundla yokugeleza ukuze uqinisekise ukuthi ukusikwa kwamadwala kuhanjiswa phansi ngesikhathi esifanele. Zivame ukusetshenziselwa ukwakheka okuthambile noma izigaba zemithombo ethambekele ekukhuleni.

Imibhobho ye-PDC yokupholisa: Ngokuklama kweshaneli egelezayo enengqondo, iletha ngokunembile uketshezi olupholisa endaweni esebenzayo yebhithi yokubhoboza, inciphisa izinga lokushisa elisebenzayo le-PDC ehlangene futhi andise impilo yesevisi yebhithi lokubhola. Asetshenziswa kakhulu emithonjeni ejulile enezinga lokushisa eliphezulu noma emisebenzini yokumba eqhubekayo yesikhathi eside.

3. Ukuhlelwa Ngokwempahla

Ngaphezu kwalokho, ngokususelwa kumehluko wezinto ezibonakalayo, imibhobho ye-PDC ingahlukaniswa ngezinhlobo ezimbili:okuhlanzekile PDC impahla kanye impahla eyinhlanganisela ye-PDC kanye ne-carbide enosimende.

Imibhobho ye-PDC ehlanzekile:Yiba nobulukhuni obuphezulu kakhulu nokumelana nokugqokwa okufanele, okufanelekile ezindaweni zokumba eziyinkimbinkimbi kakhulu.

Ama-nozzle wezinto ezihlanganisiwe:Nakuba beqinisekisa ukumelana nokugqoka, banciphisa izindleko zokukhiqiza futhi bafanele izimo zokusebenza ezijwayelekile zokumba.

Ekusetshenzisweni okungokoqobo, kuyadingeka ukukhetha ngokunengqondo uhlobo lombhobho we-PDC ngokusekelwe ezintweni ezifana nokujula kokumba, ukuqina kokwakheka, nohlobo loketshezi ukuze kukhuliswe ukusebenza kahle kokumba kanye nokwandisa izindleko. Njengoba ukuhlola nokuthuthukiswa kukawoyela kusondela ekwakhekeni okujulile nokuyinkimbinkimbi, ukwakheka kwemibhobho ye-PDC kuhlala kusungulwa. Ngokuzayo, zizothuthuka ngendlela yokuthi zingagugi, zisebenze kahle, futhi zifaneleke kakhulu izimo zokusebenza eziningi, zinikeze ukwesekwa okuqinile kwezobuchwepheshe ekuthuthukisweni kwemithombo kawoyela negesi.
