API 12 1/4 nti hybrid ntsis rau cov pob zeb tawv tob tob oilwell drilling

Hybrid laum me ntsis muaj 3 lub khob hliav qab thiab 3 hniav ob zaug zoo dua li hwm cov menyuam lub khob hliav qab.
Thaum pib ntawm lub xyoo pua xeem, lub khob hliav qab me ntsis es tsis txhob siv lub scraper hauv daim ntawv thov nyuaj abrasive, tab sis qhov kev xyaum xyaum shale thiab lwm yam tsis zoo hauv cov yas tsim yog feem ntau tshwm sim los ntawm lub siab downhole av nkos pob tuav lub luag hauj lwm, thiab nrog drilling qhov tob thiab hauv qab lub siab thiab nce. qhov feem ntawm av nkos, av nkos phenomenon yuav hnyav dua. Yuav kom daws tau qhov teeb meem no, ntau xyoo ntau lub tuam txhab tsim lub khob laum khoom ua ntau yam kev txhim kho, tab sis tsis muaj kev vam meej. Noj rau hauv tus account lub taag cutter hniav los yog laum me ntsis nyob rau hauv no hais txog tsis tshua muaj kev cuam tshuam, tib neeg pib sim ua ke ntawm ob hom laum khoom. Nrog rau qhov nrov thiab daim ntawv thov ntawm PDC cov khoom thiab PDC cutter thev naus laus zis los txhim kho cov cuab yeej ruaj khov PDC laum me ntsis hauv ntau hom kev tsim maj mam hloov lub khob me ntsis. Tab sis nyob rau hauv ib qho nyuaj, abrasive formations thiab complex directional drilling ua hauj lwm, vim qhov kev ua tau zoo, PDC laum ntsis tsis tuaj yeem hloov lub khob me ntsis. Txhawm rau ua si qhov zoo ntawm cov menyuam lub khob hliav qab thiab PDC laum khoom, peb lub tuam txhab tsis ntev los no tau tsim ib qho kev sib koom ua ke ntawm cov menyuam lub khob hliav qab thiab PDC me ntsis ntawm ib tiam tshiab ntawm kev xyaum sib xyaw. Peb tab tom tsim cov laum sib xyaw Muaj ob qhov qauv tsim, ib qho yog qhov me me ob zaug tis, ob lub khob hliav qab me ntsis, lwm qhov yog qhov loj me me ntawm Mito tis, tricone ntsis, Raws li cov laum plaub rab riam tis thiab rau cov hniav PDC laum me ntsis, thiab lwm cov hniav thiab cov haujlwm luv luv tau hloov lub khob loj. Yog li, qhov chaw nruab nrab ntawm lub borehole yog nyob rau ntawm tus kws phais tis PDC cutter ua tiav cov pob zeb tawg, thiab cov khoom siv peripheral ntawm lub borehole drilling tiav los ntawm cov cutter cutters thiab cov hniav thiab nyob rau hauv peripheral feem ntawm lub wellbore pob zeb tawg yooj yim dua, pob zeb tawg. cov nyhuv nyob ntawm lub khob hliav qab thiab cov hniav thiab mating.
Hybrid laum me ntsis thev naus laus zis sib txuas cov menyuam cones thiab PDC tsau cutters rau hauv ib qho, patented tsim los txo cov sijhawm drilling thiab kev mus ncig hauv cov kev siv nyuaj tshaj plaws.Nrog lub pob zeb-crushing lub zog thiab ruaj khov ntawm cov menyuam cones thiab txiav superiority thiab nruam shearing txiav txim ntawm pob zeb diamond. cov khoom, cov cuab yeej no nce ROP, txhim kho kev tshem tawm, thiab muaj sia nyob nrog kev sib koom ua ke nrog kev ua tau zoo sib xws thiab kev tswj cov cuab yeej zoo heev.
Hybrid laum ntsis technology
roller cones thiab polycrystalline pob zeb diamond compact (PDC) tsau cutters rau hauv ib qho, patented tsim los txo cov sij hawm drilling thiab mus ncig ua si hauv cov ntawv thov nyuaj tshaj plaws. Nrog lub pob zeb crushing lub zog thiab kev ruaj ntseg ntawm cov menyuam cones thiab txiav superiority thiab nruam shearing nkaus ntawm pob zeb diamond khoom, cov cuab yeej no tsub kom ROP, txhim kho cuttings tshem tawm, thiab muaj sia nyob heev interbedded formations nrog kev ua tau zoo sib xws thiab zoo heev toolface tswj. Thoob plaws ntiaj teb, peb cov khoom siv hybrid laum tau siv nyob rau hauv 47 lub teb chaws thiab tau xyaum ntau dua
tshaj 1 lab ft (304,800 m).
