Ama-PDC Inserts Afakwe Ngobunjwa: I-Boost ROP kuma-Medium-Hard Formations

Ezindaweni ezibanzi zaseSaudi Arabia eziqinile—i-limestone, i-dolomite, kanye ne-sandstone ehlanganisiwe—abasiki be-PDC abavamile abasicaba bavame ukubhekana nokungena kancane kanye nokuchitha amandla amaningi. Abasiki be-Axe kanye nonxantathu bashintsha umdlalo ngokugxila ekucindezelekeni, ukunciphisa amandla okusika, kanye nokuphakamisa i-ROP kakhulu. I-Ninestones Superabrasives ihola lolu shintsho lokusebenza kahle ngokusebenza kahle okuphezulu.Ukufakwa kwe-Pdc yaseShayinaeyenzelwe ukubhoboza endaweni yangempela.

Indlela Yokusika: I-PDC Ebunjiwe vs. Eyisicaba

Izicucu ezisicaba zithembele ekusikeni okugcwele, okudala ukumelana okuphezulu kanye nokugoba edwaleni eliqinile eliphakathi nendawo. Idatha evela ku-AADE (American Association of Drilling Engineers) ikhombisa ukuthi izicucu ezimise okwesimo zisebenzisa ukungena kwe-point-load ukuze ziqhekeze idwala ngaphambi kokuqhekeka, zisika i-MSE (Mechanical Specific Energy) ngamaphesenti afinyelela ku-35.

Izithako ezimise okwe-axe zisebenzisa umugqa obukhali ukuze zihlukanise idwala kuqala, bese zisika. Izithako ezimise okwe-triangular prismatic zisebenzisa imiphetho emithathu elinganayo ukuze ziqhekeke ngokuzinzile nangokuqhubekayo. Zombili lezi jiyometri zibhoboza ngokushesha nge-WOB encane, ziphakamisa i-ROP ngqo.

Kufika ku-35% ukwehliswa kwe-Mechanical Specific Energy (MSE)— kufakazelwe idatha yensimu ye-AADE kusetshenziswa i-geometry yesikhiphi se-PDC esimile.

Kungani i-Pdc ye-Shaped China ifaka i-Excel ku-Medium-Hard Rock

OkubunjiweUkufakwa kwe-Pdc yaseShayinauletha izinzuzo ezintathu ezibalulekile ezifakazelwe yizifundo zasensimini ze-OnePetro:

Okwakhiwe ngamatshe e-NinestonesUkufakwa kwe-Pdc yaseShayinahlanganisa i-geometry elungiselelwe kahle ne-PCD yezinga eliphezulu, isivinini sokulinganisela kanye nokuqina okungcono kunezicucu ezijwayelekile ezisicaba.

Icala Lensimu: Ukweqa kwe-ROP Ekwakhekeni kwe-Saudi Carbonate

Ithimba lokubhoboza emasimini ase-carbonate ase-Saudi Arabia lihlole i-NinestonesUkufakwa kwe-Pdc yaseShayinangokumelene nezicucu ezijwayelekile ezisicaba:

Uhlobo Lokusika	I-ROP	Isimo
Abasiki Abayisicaba	2.1 m/h	Ukuqhekeka njalo
Ukufakwa kwe-Pdc okubunjiwe kweShayina	3.4 m/h(+62%)	Akukho ukuqhekeka

Ingxenye yomthombo yaphela ezinsukwini eziyi-1.5 ngaphambi kwesikhathi, yanciphisa izindleko eziphelele ngo-28%. Abaphathi bendawo baqinisekisile ukuthi izingcezu ezimile zihlale zibukhali isikhathi eside.

Xhumana nama-Ninestones Superabrasives

Mayelana noMlobi

UKhalid Al-Faraj, unjiniyela wokubhoboza oseDammam, eSaudi Arabia, uneminyaka engu-19 yesipiliyoni ekusebenzeni kukawoyela negesi ogwini kulo lonke elaseMbusweni. Ugxile ekwenzeni ngcono ama-bit e-PDC, ekuthuthukiseni i-ROP, kanye nokukhetha amathuluzi ahambisana nokwakheka.

"OkwaboUkufakwa kwe-Pdc yaseShayinayimikhiqizo ye-PDC enomumo omuhle kakhulu engiyisebenzisile ezinhlotsheni zaseSaudi. Ziletha izinzuzo ze-ROP eziqhubekayo, ukuqina okukhulu, kanye nokutholakala okuthembekile. Kunoma yimuphi umqhubi ohlose ukusheshisa ukubhoboza okuphakathi nendawo, i-Ninestones iyisinqumo esiphezulu.
