Mafuta a Petroleum Drill Bit

Mafuta a Petroleum Drill Bit

Kubowola kwa petroleum kumagwira ntchito yofunika kwambiri pakubowola mafuta, kumathandizira kwambiri pakubowola bwino, kuchita bwino, komanso mtengo wake. Mitundu ya zida zobowola petroleum imaphatikizapo scraper bits, roller cone bits, diamondi bits, ndi PDC bits (polycrystalline diamond compact bits). Nkhaniyi ikufotokoza za scraper bits.

Tizilombo ta scraper tinali m'gulu loyamba lomwe limagwiritsidwa ntchito pobowola mozungulira, kuyambira m'zaka za zana la 19 ndipo limagwiritsidwabe ntchito m'malo ena opangira mafuta masiku ano. Amachita bwino kwambiri m'mapangidwe ofewa komanso omatira, omwe amapereka liwiro la kubowola pamakina komanso luso lolowera. Ma bits a Scraper amayamikiridwa chifukwa cha mapangidwe awo osavuta, okwera mtengo, komanso osinthika popanga makonda m'minda yamafuta.

Kachidutswa kakang'ono kamakhala ndi thupi pang'ono, scraper masamba, nozzles, ndi bullnose. Thupi laling'ono, lopangidwa kuchokera ku chitsulo chapakati-carbon, limakhala ndi scraper blade ndi mphuno yamphongo kumapeto kwapansi, ndi zolumikizira za ulusi kumapeto kumtunda kuti zigwirizane ndi chingwe chobowola. Ma scraper blades, omwe amadziwikanso kuti mapiko, ndi zigawo zofunika kwambiri za scraper bits.

Ma Scraper bits amapereka magwiridwe antchito apamwamba pamapangidwe ofewa komanso omatira. Pobowola, kuwongolera bwino mphamvu yakubowola ndi liwiro lozungulira ndikofunikira kuti tipewe kupatuka ndi kusweka kwa tsamba. Popeza mkulu mawotchi pobowola liwiro mu zofewa mapangidwe ndi chifukwa chachikulu buku la cuttings, ntchito mkulu-voliyu pobowola madzimadzi tikulimbikitsidwa kuonetsetsa bwinobwino kuyeretsa pobowo pansi ndi ogwira kuzirala kwa pang'ono. Kuphatikiza apo, kuthamanga kwapang'onopang'ono kwa mapiko a scraper bit kungayambitse kuvala kwa conical, zomwe zimafuna njira zosamala kuti tipewe kuchepera kwa bore ndi kupatuka kwina.

Kupatula momwe amachitira bwino pamapangidwe ofewa komanso omata, ma scraper bits akuwonetsanso zabwino m'malo ena achitukuko. Mwachitsanzo, m'malo otentha kwambiri komanso opanikizika kwambiri, ma scraper bits amakhalabe okhazikika, kuonetsetsa kuti ntchito zobowola zotetezeka komanso zogwira mtima. Kusinthasintha kumeneku kumapangitsa kuti ma scraper bits akhale chisankho chofunikira kwambiri pakubowola mafuta, kaya pochotsa mafuta achikhalidwe kapena poyang'anizana ndi zovuta zomwe zikuchitika m'madzi akuya komanso madera akuya kwambiri, kutsimikizira kufunika kwawo komanso kuthekera kwawo.
