Iyo gomba inovhura ndeye micro eccentric reamer, iyo inogona kubatanidzwa kune tambo yekuchera kuti uwane micro reaming uchidhirowa. Chishandiso chine mapoka maviri emaspiral reamer blades. Boka rezasi reblade ndiro rine basa rekudzoreredza pachiri kuchera kana kudzoreredza zvakanaka panguva yekuchera, uye boka repamusoro blade ndiro rine mutoro wekudzosera kumashure panguva yekuchera. Basa guru remudziyo nderokudzikisa kuoma kwembwa mutsime rekutungamirira, kubvisa pasi gomba diki-doglegs uye nhanho diki, uye kuwedzera chibhorani nehupamhi hwakati kurei kupfuura dhayamita yetioretical yechiboorero mune yakawedzera shale. kuumbwa uye inokambaira yemunyu-gypsum layer, yakapfava mudstone layer, marasha seam uye zvimwe zvikamu zvetsime, izvo zvinogona kuderedza kudzoreredza kuvhiya nguva muyakajairwa kuchera uye kuve nekuchengetedza uye kutsetseka kushanda kwekutsika, matanda emagetsi, casing kumhanya uye kuwedzera paki. . Pamusoro pezvo, chishandiso chinewo basa rekubvisa mubhedha wekucheka mumatsime akananga uye kunyatso kudzora ECD yematsime akachinjika uye matsime akareba anosvika.

2. Chikamu chekushandiswa

· Matsime emvura

· kureba kusvika zvakanaka

· Salt-gypsum layer, soft mudstone layer, marasha seam uye mamwe anokambaira strata

· Hydration yakawedzera strata

· Serious cuttings mubhedha zvakanaka

3. Mamiriro ezvinhu

· Chikamu chimwe chete, hapana zvikamu zvinofamba, simba rakakwirira kudarika simba repombi yekuchera yakabatana nayo

· Yakabatanidzwa nekoramu yekuchera pombi, haikanganisi kuiswa kwekoramu uye maviri-layer platform operation kune akawanda derricks.

· Hydraulic, mechanic kaviri chiito kukuvara, bvisa mubhedha wekucheka

· Huviri-pakati hunhu hunogona kuwedzera saizi yegomba yakakura kupfuura chishandiso kuburikidza nedhayamita

· The spiral blade inobatsira kuvandudza kugadzikana kwetambo yekuchera panguva yekushanda

· Iwo epamusoro uye epasi ekucheka zvimiro anogona kuwana yakanaka reming kana inverted reming

· Inogona kushandiswa kugadzira chibhorani chisati chatemwa magetsi, casing kumhanya uye kuwedzera packer kumhanya.

· Kuderedza kana kubvisa micro-imbwa makumbo

· Deredza nguva yekudzokorora uye nhamba yematsime
