Kodi Reverse Circulation Drilling ndi chiyani

Kodi Reverse Circulation Drilling ndi chiyani?

Kubowola kwa reverse circulation ndi njira yobowola yomwe imagwiritsidwa ntchito reverse circulation PDC bits, ndi ndodo zokhala ndi makoma awiri kuti akwaniritse kubowola ndi kusonkhanitsa zitsanzo. Khoma lakunja limakhala ndi machubu amkati omwe amalola kuti zodulidwazo zibwererenso pamwamba pomwe ntchito yoboola ikupitilira.

Kubowola kwa ma reverse kumalolabe zotsegula mabowo koma kumasiyana ndi kubowola diamondi chifukwa kumatolera zidutswa za miyala m'malo mwa rock core. Kubowolako kumagwiritsa ntchito tizidutswa tapadera tozungulira mozungulira motsogozedwa ndi pisitoni yobwezera mpweya kapena nyundo.

Mabowo ozungulirawa amapangidwa ndi tungsten, chitsulo, kapena kuphatikiza ziwirizo chifukwa ndi zamphamvu zodula ndikuphwanya mwala wolimba kwambiri. Kupyolera mu kayendedwe ka pisitoni, nyundoyo imatha kuchotsa mwala wophwanyidwa, womwe umaperekedwa pamwamba ndi mpweya woponderezedwa. Mpweya umawomba pansi pa annulus. Izi zimapanga kusintha kwamphamvu komwe kumabweretsa kuzunguliridwa kwa reverse, komwe kumatulutsa zodulidwazo pamwamba pa chubu.

Kubowola mozungulira mozungulira ndikwabwino poyesa zitsanzo za miyala ya pansi pa nthaka kuti iwunikenso stratification ndi zolinga za uinjiniya wa maziko.

Tsopano popeza mukudziwa chomwe chiri, tiyeni tiwone zina mwazabwino zobowola mozungulira.

Zothandiza Kupeza Zitsanzo Zosaipitsidwa

Kubowola mobwerezabwereza kumathetsa kuipitsidwa kulikonse kwa miyala yodulidwa ikaperekedwa pamwamba, pamene zodulidwazo zimayenda kudzera mu chubu chamkati chokhala ndi mpata umodzi wokha pamwamba pomwe zitsanzo zimasonkhanitsidwa. Choncho, mukhoza kusonkhanitsa zitsanzo zambiri zapamwamba kuti muwunike.

Zodabwitsa Zolowera

Mabiti apadera ozungulira ozungulira amakhala amphamvu kwambiri kuposa momwe amamalizidwira bwino chifukwa cha nsonga za tungsten-zitsulo. Kubowola mobwerezabwereza kumagwira ntchito mwachangu kwambiri ndikuchotsa zodulidwazo munthawi yojambulira. Kuthamanga komwe kudulako kumabwezeredwa pamwamba kumatha kuyang'ana pa 250 metres pa sekondi iliyonse.

Kusinthasintha mu Mikhalidwe Yoipa

Kubowola mobwerezabwereza sikovuta ndipo sikufuna madzi ambiri. Izi zimapangitsa kubowola kozungulira kozungulira kukhala koyenera ngakhale m'malo omwe madzi ndi osowa ngati kumadera akumidzi kapena kouma.

Zotsika mtengo

Kubowola mozungulira mozungulira ndikotsika mtengo kwambiri, makamaka poyerekeza ndi kubowola diamondi. Osati kokha chifukwa cha kuchepa kwa mtengo wa ntchito, komanso chifukwa cha nthawi yochepa yomwe imafunika kuti amalize kubowola. Ponseponse, kubowola mobwerezabwereza kumatha kutsika ndi 40% poyerekeza ndi kubowola wamba. Ngati mukubowola m'madera omwe ali ndi malo ovuta, mtengo wake ukhoza kuwirikiza kawiri.

Reverse Circulation for Grade Control

Ubwino wa zitsanzo zomwe zapezedwa ndizofunika kwambiri mu pulogalamu iliyonse yowunikira kuti akwaniritse kukonzekera bwino kwa migodi kapena kuyika zophulika. Kuwongolera kalasi ndizomwe zimagwiritsidwa ntchito kutanthauzira midadada ndi magiredi ore. Kubowola kwa reverse circulation ndikwabwino pakuwongolera kalasi chifukwa:

• Pamafunika kusamala kocheperapo kusiyana ndi njira zina
• Zitsanzo zomwe zapezedwa zilibe zoipitsa zilizonse
• Nthawi yotembenuza mwachangu
• Zitsanzo zomwe zapezeka zitha kutengedwa molunjika ku labu kuti zikawunikidwe

Chofunikira kwambiri pakubowola kwamtundu uliwonse ndikudula zitsanzo. Njira zambiri zitha kugwiritsidwa ntchito pakuchira kwachitsanzo, koma cholinga chachikulu ndikupeza zitsanzo zabwino kwambiri munthawi yochepa kwambiri.

Ngati mukufuna ntchito zobowola m'mbuyo, kumbukirani kufunafuna akatswiri okhawo omwe ali ndi zilolezo omwe amadziwa njira yawo pobowola mozungulira komanso odziwa bwino njira zosiyanasiyana. Funsani kuti azingogwiritsa ntchito zapamwamba zovomerezekareverse circulation PDC bitskupewa kuchedwa kulikonse kobwera chifukwa cha zobowola zosweka. Pomaliza, nthawi zonse onetsetsani kuti kubowola kukugwirizana ndi zomwe zakhazikitsidwa.
