Isingeniso
Ukuze kuthuthukiswe ukusebenza kwe-tricone drill bit, izici ezimbalwa ezibalulekile zenziwe.
1, Ijethi ye-C-Center, isibonelo, iklanyelwe ukuvimbela ukwakheka kwebhola ngaphakathi kwebhithi.Lesi sici sisiza ukuqeda noma iyiphi indawo ewuketshezi ezansi komthombo, sisheshisa ukugeleza okuya phezulu kokusikwa kokumba, futhi ekugcineni sithuthukise izinga lokungena (ROP).
2, Amabheringi e-NBR agcwele amanzi ahlanganiswe ekwakhiweni kwe-tricone drill bit ukusiza ukwehlisa ingcindezi yokuvala futhi kuthuthukiswe ukuthembeka kophawu.Lokhu kuguqulwa kubalulekile ngoba kungasiza ekuvimbeleni ukuvuza, okungabiza futhi kube yingozi.
3, isici sokuvikela i-G-Gauge sibalulekile futhi ngoba sithuthukisa ikhono lokulinganisa le-tricone drill bit ngenkathi sandisa impilo yayo yesevisi.Ngalesi sici, abasebenzisi bangalindela izilinganiso ezinembe kakhudlwana, ezingaholela ekusebenzeni kangcono kokumba kanye nemiphumela.
4, Okokugcina, ukwengeza umugqa owengeziwe wamazinyo phakathi kwe-taper yangemuva nokuphumayo kufakazele ukuthi kuyindlela esebenzayo yokunquma imbobo nokuvikela ikhoni.Lesi sici sisiza ekunciphiseni ukuguga nokudabuka kwe-tricone drill bit, okuholela esikhathini eside sempilo nokusebenza okungcono.
Kafushane, i-tricone drill bit iyithuluzi eliguquguqukayo nelithembekile elingasetshenziselwa uhla lwezinhlelo zokusebenza zokumba.Ngokuhlanganisa izici ezintsha ezifana nejethi ye-C-Center, ama-NBR amabheringi, ukuvikelwa kwe-G-Gauge, nomugqa owengeziwe wamazinyo, ukusebenza kwebhithi ye-tricone drill nokuphila kungathuthukiswa kakhulu.
Izici
1. I-Drill Bit Connection eyenziwe ngokwezinga le-API.
2. Singalungisa usayizi omncane ngokuya ngerigi yakho.
I-3.Izakhiwo zokusika eziqinisekisiwe kanye nemiklamo yokuzala iyaqhubeka nokuletha izinga eliphezulu lokusebenza nokuthembeka.
I-4.Optimized hydraulics inikeza i-ROP eyengeziwe ngokususa kahle ukusikwa nokuqinisekisa ukubandakanyeka kwedwala elisha kukho konke ukujikeleza kwesakhiwo sokusika.
