API 12 1/4 inches hybrid bit for hard rock deep deep oilwell drilling

Hybrid drill bit ine makoni matatu uye 3 mablades ari nani zvakapetwa kaviri pane premium roller cone bits.
Pakutanga kwezana remakore rapfuura, iyo cone drill bit pachinzvimbo cheiyo scraper mune yakaoma abrasive formations application, asi ichi chibooreso shale uye zvimwe zvinokanganisa mukugadzirwa kwepurasitiki zvinonyanya kukonzerwa nekumanikidza downhole mud pack inobata basa, uye nekuchera kudzika uye bottomhole kumanikidza uye kuwedzera. chikamu chedhaka, mud pack phenomenon ichave yakakomba. Kugadzirisa dambudziko iri, nekufamba kwemakore vagadziri vakasiyana-siyana mabhiti ekubooresa vakagadzira zvakasiyana siyana, asi nekubudirira kushoma. Tichifunga nezvechinochekwa chekucheka blade kana chibooreso munyaya iyi zvisinganyanyi kukanganiswa, vanhu vakatanga kuedza musanganiswa wemhando mbiri dzezvibooreso. Nekuzivikanwa uye kushandiswa kwePDC bits uye PDC cutter tekinoroji yekuvandudza yakagadzika cutter PDC drill bit muakasiyana mafomati zvishoma nezvishoma inotsiva cone bit. Asi mune yakaoma, abrasive maumbirwo uye yakaoma directional drilling mashandiro, nekuda kwekuita, PDC drill bit haigone kutsiva cone bit. Kuti titambe zvakanakira roller cone uye PDC drill bits, kambani yedu ichangobva kugadzira yakasanganiswa roller cone uye PDC diki yechizvarwa chitsva checomposite drill. Tiri kuvhura composite drill Pane maviri madhizaini, imwe idiki saizi kaviri bapiro, kaviri-cone bit, imwe yakakura zvishoma saizi yeMito wing, tricone bit, Kubva pane izvi zvibooresa mapanga mana mapapiro uye matanhatu mashizha PDC drill bit, uye vice blades uye zvinzvimbo zvipfupi zvakatsiviwa saizi yekoni. Saka, nzvimbo yepakati pechibhorani iri pane anovhiya bapiro PDC cutter akazara matombo, uye chikamu cheperipheral chekuchera chibhorani chinopedzwa nevacheki vekucheka uye mapanga uye padivi pechikamu chetsime redombo rinoputika zvakanyanya kuoma, kutsemuka kwedombo. mhedzisiro inoenderana nekoni uye mashizha uye kusangana.
Hybrid drill bit tekinoroji inosanganisa roller koni uye PDC yakagadzika cutter kuita imwechete, dhizaini ine kodzero yekudzikisa nguva yekuchera uye nzendo mune zvakanyanya kuomarara maapplication.Nesimba rekupwanya dombo uye kugadzikana kwemaroller cones uye kuchekwa kwehukuru uye kuenderera mberi kwekuveura kwedhaimani. bits, tekinoroji iyi inowedzera ROP, inokuvadza kubviswa kwekucheka, uye inopona yakapindirana maumbirwo ane kuita kunoenderana uye yakanakisa toolface control.
Hybrid drill bit technology
roller cones uye polycrystalline diamond compact (PDC) yakagadzika kucheka kuita imwechete, dhizaini ine patent kuderedza nguva yekuchera uye nzendo mune zvakanyanya kuoma maapplication. Iine simba rekupwanya dombo uye kugadzikana kwemaroller cones uye kuchekwa kwepamusoro uye kuenderera mberi kwekuveura kwedhaimondi bits, tekinoroji iyi inowedzera ROP, inovandudza kubviswa kwekucheka, uye inopona yakanyatso kupindirana maumbirwo ane mashandiro anoita uye yakanakisa toolface control. Pasi rose, zvibhorani zvedu zvakasanganiswa zvakashandiswa munyika makumi mana nenomwe uye zvakadhirowa zvimwe
kupfuura miriyoni imwe ft (304,800 m).
