Chotsegulira dzenje ndi micro eccentric reamer, yomwe imatha kulumikizidwa ndi chingwe chobowola kuti ikwaniritse micro reaming pomwe mukubowola. Chidachi chili ndi magulu awiri a spiral reamer blades. Gulu lakumunsi la tsamba limayang'anira kubwezeretsanso pamene mukubowola kapena kubwezeretsanso bwino panthawi yobowola, ndipo gulu lapamwamba la tsamba limayang'anira kubwezeretsanso panthawi yomwe mukubowola. Ntchito yaikulu ya chida ndi kuchepetsa kuopsa kwa dogleg mu chitsime directional, kuchotsa downhole yaying'ono-doglegs ndi masitepe ang'onoang'ono, ndi kukulitsa borebo ndi m'mimba mwake lalikulu pang'ono kuposa theoretical m'mimba mwake wa kubowola pang'ono kubowola mu shale expansive. mapangidwe ndi zokwawa mchere gypsum wosanjikiza, zofewa mudstone wosanjikiza, malasha msoko ndi zigawo zina chitsime, amene angathe kuchepetsa reming ntchito nthawi mu ndondomeko ochiritsira pobowola ndi kuonetsetsa otetezeka ndi yosalala ntchito yokhotakhota, mitengo magetsi, casing kuthamanga ndi kukulitsa packer. . Komanso, chida alinso ntchito kuchotsa cuttings bedi mu zitsime malangizo ndi bwino kulamulira ECD ya zitsime yopingasa ndi anawonjezera kufikira zitsime.

2. Kuchuluka kwa ntchito

· Hydraulic, mechanical double action kuwonongeka, chotsani bedi la cuttings

· Makhalidwe apawiri apakati amatha kukulitsa chitsime kukula kuposa chida kudzera m'mimba mwake

· Tsamba lozungulira limathandizira kukhazikika kwa chingwe chobowola panthawi ya opaleshoni

· The chapamwamba ndi m'munsi kudula nyumba akhoza kukwaniritsa reming zabwino kapena inverted reming

· Itha kugwiritsidwa ntchito popangira borehole musanayambe kudula mitengo yamagetsi, kuthamanga kwa casing ndikuwonjezera packer kuthamanga

· Kuchepetsa kapena kuthetsa yaying'ono-galu miyendo
