Petroleum Drill Bit

Petroleum Drill Bit

Cov roj av laum me ntsis plays lub luag haujlwm tseem ceeb hauv cov roj drilling, ua rau muaj kev cuam tshuam rau qhov zoo, kev ua haujlwm, thiab cov nqi. Cov khoom siv roj av muaj xws li cov khoom siv scraper, cov menyuam lub khob hliav qab, cov khoom siv pob zeb diamond, thiab PDC cov khoom (polycrystalline pob zeb diamond compact khoom). Kab lus no tsom ntsoov rau cov khoom scraper.

Scraper khoom yog thawj zaug siv nyob rau hauv rotary drilling, originating nyob rau hauv lub xyoo pua 19th thiab tseem ua hauj lwm nyob rau hauv tej oilfields niaj hnub no. Lawv ua tau zoo nyob rau hauv cov mos mos thiab nplaum formations, muab siab mechanical drilling ceev thiab muaj peev xwm nkag mus. Scraper khoom muaj nuj nqis rau lawv cov qauv tsim yooj yim, kev siv nyiaj zoo, thiab kev hloov kho rau kev tsim khoom hauv ib tus neeg cov roj av.

Ib tug scraper me ntsis muaj ib tug me ntsis lub cev, scraper hniav, nozzles, thiab ib tug bullnose. Lub cev me ntsis, ua los ntawm nruab nrab-carbon steel, nta welded scraper hniav thiab ib tug bullnose nyob rau hauv qis kawg, nrog threaded kev twb kev txuas nyob rau hauv lub Upper kawg rau txuas mus rau lub laum txoj hlua. Scraper hniav, tseem hu ua tis, yog cov khoom tseem ceeb ntawm cov khoom scraper.

Scraper khoom muab kev ua tau zoo tshaj plaws hauv cov khoom muag muag thiab nplaum. Thaum lub sijhawm ua haujlwm drilling, kev tswj xyuas meej ntawm qhov drilling siab thiab kev sib hloov ceev yog qhov tseem ceeb los tiv thaiv kev sib txawv thiab cov hniav tawg. Muab lub siab mechanical drilling ceev nyob rau hauv mos formations thiab lub resulting loj ntim ntawm cuttings, siv high-volume drilling kua yog pom zoo kom ua kom huv si ntxuav ntawm lub borehole hauv qab thiab zoo txias ntawm me ntsis. Ntxiv mus, qhov nce peripheral ceev ntawm scraper me ntsis tis tuaj yeem ua rau conical hnav, yuav tsum tau ceev faj ntsuas los tiv thaiv borehole nqaim thiab ntxiv deviation.

Tshaj li lawv cov kev ua tau zoo heev hauv cov qauv mos thiab nplaum, cov khoom scraper kuj qhia tau zoo hauv lwm qhov kev loj hlob. Piv txwv li, nyob rau hauv high-temperature thiab high-pressure ib puag ncig, scraper khoom tuav ruaj khov kev ua tau zoo, ua kom muaj kev nyab xeeb thiab ua haujlwm zoo drilling. Qhov kev ua tau zoo no tsim cov khoom siv scraper raws li qhov kev xaiv tsis tseem ceeb hauv cov roj av drilling, txawm tias nyob rau hauv cov tsoos roj extraction los yog ntsib cov teeb meem tshwm sim ntawm cov dej tob thiab ultra-dej-dej cheeb tsam, underscoring lawv tus nqi tshwj xeeb thiab daim ntawv thov muaj peev xwm.
