Kodi Kubowola Kozungulira Mozungulira ndi Chiyani?

Kodi Kuboola Kozungulira Mozungulira (Reverse Circulation Drilling) n'chiyani?

Kubowola mozungulira ndi njira yobowola yomwe imagwiritsa ntchito ma PDC bits ozungulira mozungulira, ndi ndodo zokhala ndi makoma awiri kuti zibowoledwe ndi kusonkhanitsa zitsanzo. Khoma lakunja lili ndi machubu amkati omwe amalola kuti zidutswazo zibwerere pamwamba pamene ntchito yobowola ikupitirira.

Kuzungulira kwa m'mbuyo kumalolabe kulumikizidwa kwa zotsegulira mabowo koma kumasiyana ndi kuboola diamondi chifukwa kumasonkhanitsa zidutswa za miyala m'malo mwa maziko a miyala. Bowolo limagwiritsa ntchito zidutswa zapadera zozungulira za m'mbuyo zomwe zimayendetsedwa ndi pistoni yobwerezabwereza ya pneumatic kapena nyundo.

Zidutswa zobowolera zozungulira izi zimapangidwa ndi tungsten, chitsulo, kapena kuphatikiza ziwirizi chifukwa zimakhala zolimba mokwanira kudula ndi kuphwanya miyala yolimba kwambiri. Kudzera mu kayendedwe kake ka pistoni, nyundo imatha kuchotsa mwala wosweka, womwe umatumizidwa pamwamba ndi mpweya wopanikizika. Mpweya umawomba pansi pa annulus. Izi zimapangitsa kusintha kwa kupanikizika komwe kumabweretsa kuyenda kwa magazi mobwerera, komwe kumatumiza zidutswazo m'chubu.

Kuboola mozungulira ndikwabwino kwambiri poyesa zinthu za miyala yapansi panthaka poyesa kugawa madera ndi kupanga maziko.

Tsopano popeza mukudziwa tanthauzo lake, tiyeni tiwone ubwino wina wa kuboola pogwiritsa ntchito njira yozungulira.

Zothandiza Popeza Zitsanzo Zosadetsedwa

Kuboola mozungulira m'mphepete mwa miyala kumachotsa kuipitsidwa kulikonse kwa miyala yodulidwa ikaperekedwa pamwamba, pamene zidutswazo zimadutsa mu chubu chamkati chotsekedwa ndi kabowo kamodzi kokha pamwamba pomwe chitsanzocho chimasonkhanitsidwa. Chifukwa chake, mutha kusonkhanitsa zitsanzo zambiri zapamwamba kuti muzisanthule.

Mitengo Yodabwitsa Yolowera

Ma bits apadera ozungulira kumbuyo ndi olimba kwambiri kuposa ma bits wamba chifukwa cha nsonga zopangidwa ndi chitsulo cha tungsten. Ma drill ozungulira kumbuyo amagwira ntchito mwachangu ndipo amachotsa zodulidwazo munthawi yochepa. Liwiro lomwe zodulidwazo zimabweretsedwa pamwamba limatha kuonekera mosavuta pa mamita 250 pa sekondi.

Kusinthasintha mu Mikhalidwe Yoipa

Kuboola mozungulira mozungulira si ntchito yovuta ndipo sikufuna madzi ambiri. Izi zimapangitsa kuti kuboola mozungulira mozungulira mozungulira kukhale koyenera ngakhale m'malo omwe madzi ndi ochepa monga m'madera akuluakulu akumidzi kapena m'madera ouma pang'ono.

Zotsika Mtengo

Kuboola mozungulira mozungulira ndi kotsika mtengo kwambiri, makamaka poyerekeza ndi kuboola diamondi. Sikuti chifukwa cha kuchepa kwa ndalama zogwirira ntchito, komanso chifukwa cha nthawi yochepa yomwe imatenga kuti kuboola kumalize. Ponseponse, kuboola mozungulira mozungulira mozungulira kumatha kuwononga ndalama zochepera mpaka 40% kuposa kuboola wamba. Ngati mukuboola m'malo okhala ndi malo ovuta, kugwiritsa ntchito bwino ndalama kumatha kuwirikiza kawiri.

Kuzungulira Kobwerera M'mbuyo kwa Kulamulira Magiredi

Ubwino wa zitsanzo zomwe zapezeka ndi wofunikira kwambiri pa pulogalamu iliyonse yofufuza kuti achite kukonzekera bwino migodi kapena kuyika mabomba. Kuwongolera magiredi ndi komwe kumagwiritsidwa ntchito pofotokoza mabuloko ndi magiredi a miyala. Kubowola magiya ozungulira kumbuyo ndikwabwino powongolera magiredi chifukwa:

• Zimafuna chisamaliro chochepa kuposa njira zina
• Zitsanzo zomwe zapezedwa zilibe zodetsa zilizonse
• Nthawi yofulumira yotembenukira
• Zitsanzo zomwe zapezedwa zitha kutengedwa mwachindunji ku labu kuti zikawunikidwe

Chinthu chofunika kwambiri pa ntchito iliyonse yobowola mozungulira ndi kudula zitsanzo. Njira zambiri zingagwiritsidwe ntchito pobwezeretsa zitsanzo, koma cholinga chachikulu ndikupeza zitsanzo zabwino kwambiri momwe zingathere munthawi yochepa kwambiri.

Ngati mukufuna ntchito iliyonse yoboola pogwiritsa ntchito njira yozungulira, kumbukirani kufunafuna akatswiri ovomerezeka okha omwe amadziwa bwino njira yawo yoboola pogwiritsa ntchito njira yozungulira pogwiritsa ntchito njira yozungulira komanso odziwa bwino njira zosiyanasiyana. Pemphani kuti agwiritse ntchito njira yovomerezeka yokha.ma PDC bits ozungulira mozungulirakuti mupewe kuchedwa kulikonse komwe kungachitike chifukwa cha zidutswa zobowola zosweka. Pomaliza, nthawi zonse onetsetsani kuti njira yobowola ikutsatira miyezo yokhazikika ya chilengedwe.
