Wopereka API wa petroleum drill bits for very hard rock

API yogulitsa gasi yachilengedwe ya tricone kubowola miyala yokhala ndi nkhope yachitsulo yosindikizidwa kuchokera ku fakitale yaku China.
Kufotokozera Pang'ono:
IADC: Magazini ya 517-TCI yosindikizidwa pang'ono yokhala ndi chitetezo cha geji kuti ikhale yofewa mpaka yapakatikati yokhala ndi mphamvu zochepa.
Compressive Mphamvu:
85-100 MPA
12,000-14,500 PSI
Kufotokozera Pansi:
Miyala yolimba yapakati komanso yonyezimira monga miyala yamchenga yokhala ndi mizere ya quartz, miyala yamchere yolimba kapena chert, miyala ya hematite, miyala yolimba, yolumikizidwa bwino monga: miyala yamchenga yokhala ndi quartz binder, dolomites, quartzite shales, magma ndi metamorphic coarse grained rocks.
Titha kupereka ma tricone kukula kwake kosiyanasiyana (kuyambira 3 mpaka 26) ndiZambiri za IADC Codes.
Monga njira yodula mitengo ya geophysical, imatha kupeza zambiri zamitundu yosiyanasiyana ya miyala yapansi panthaka ndi zigawo zamchere.
Monga njira yopangira, imatha kuwona momwe zinthu zilili pansi pa nthaka komanso mphamvu zamadzimadzi pansi pa nthaka.
Kugwiritsa ntchito bwinobore kuwononga mafuta apansi panthaka, gasi, madzi apansi panthaka, zinthu za geothermal.
Njira yomwe imagwiritsidwa ntchito pobowola mabowo pofufuza ndikukula mafuta ndi gasi.
Zimaphatikizapo kamangidwe ka chitsime, kusankha kobowola ndi matope, kuphatikiza zida zobowola, kugwirizanitsa magawo obowola, kuwongolera kupatuka, kuchiritsa matope, kukokera, kupewa ngozi, ndi chithandizo, etc.
Makhalidwe aukadaulo wobowola mafuta ndi dzenje lakuya, kuthamanga kwambiri, kutentha kwambiri, ndi zinthu zambiri zomwe zimakhudza.
Malinga ndi momwe chilengedwe komanso malo alili komanso zosowa zamainjiniya pakufufuza ndi chitukuko chamafuta ndi gasi, pali mitundu iwiri ya Wells of the vertical Wells and directional Wells.Zomalizazi zitha kugawidwa m'ma Wells olunjika, zitsime zopingasa, ndi zitsime zamagulu.
