(1) Kukurumidza kuvaka
Sezvo jira rekuchera rinotenderera richitenderera nekupwanya dombo nevhu nebharero nevharuvhu pasi, uye richiisa zvakananga mubhaketi rekuchera kuti risimudzwe uye riendeswe pasi, hapana chikonzero chekupwanya dombo nevhu, uye matope anodzoserwa kubva mugomba. Avhareji yefootage paminiti inogona kusvika 50cm. Kubudirira kwekuvaka kunogona kuwedzerwa ne5 ~ 6 times zvichienzaniswa neyayo yemuchina wekuchera pile uye muchina wekuboorera pile mu stratum yakakodzera.
(2) Kunyatsorongeka kwekuvaka. Munguva yekuvaka, kudzika kwemurwi, kumira, WOB uye kugona kwevhu mugomba rekuboorera zvinogona kudzorwa nekombiyuta.
(3) Ruzha rwakaderera. Ruzha rwekuvaka rwe rotary drilling rig runonyanya kugadzirwa neinjini, uye hapana ruzha rwekukweshana kune zvimwe zvikamu, izvo zvinonyanya kukodzera kushandiswa mumaguta kana mudzimba.
(4) Kuchengetedzwa kwezvakatipoteredza. Huwandu hwevhu hunoshandiswa pakuvaka gomba rekuboorera hushoma. Basa guru revhu pakuvaka nderekuwedzera kugadzikana kwemadziro emakomba. Kunyangwe munzvimbo dzine kugadzikana kwakanaka kwevhu, mvura yakachena inogona kushandiswa kutsiva vhu pakuvaka gomba, izvo zvinoderedza zvikuru kuburitswa kwevhu, hazvina simba guru panharaunda yakapoteredza, uye zvinochengetedza mari yekutakura vhu kunze.
(5) Zviri nyore kufamba.Chero bedzi simba rekutakura zvinhu panzvimbo iyi richikwanisa kusangana nezvinodiwa nemuchina wekuboorera unotenderera, unogona kufamba wega pamuchina wekukambaira pasina kushandira pamwe kwemimwe michina.
(6) Kushandiswa kwemichina kwakanyanya. Munguva yekuvaka, hapana chikonzero chekuputsa nekubatanidza pombi yekuboorera nemaoko, uye hapana chikonzero chekubvisa tsvina yematope, izvo zvinogona kuderedza simba revashandi nekuchengetedza vashandi.
(7) Hapana magetsi anodiwa.
Parizvino, mini rotary drilling rig inoshandiswa pamusika inoshandisa injini yedhiziri yefuselage kupa simba, iro rakakodzera nzvimbo yekuvaka isina simba. Panguva imwe chete, inobvisawo kutakurwa, kurongeka uye dziviriro yetambo, uye ine kuchengetedzeka kwakanyanya.
(8) Murwi mumwe chete une simba guru rekutakura zvinhu. Nekuti muchina wekuchera unocheka ivhu nekona yepasi pesilinda kuti ugadzire gomba, madziro egomba anenge akaomarara mushure mekunge gomba raumbwa. Kana tichienzanisa nemurwi wakaboorwa, madziro egomba haana kana kumboisa ivhu. Mushure mekunge murwi waumbwa, muviri wemurwi wakabatana zvakanaka nevhu, uye simba rekutakura zvinhu remurwi mumwe chete rakakwira.
(9) Inoshanda kune akasiyana-siyana ema strata. Nekuda kwekusiyana kwema drill bits e rotary drilling rig, rotary drilling rig inogona kushandiswa kune akasiyana strata. Mukuita kumwe chete kwekuvaka murwi, inogona kupedzwa ne rotary drilling rig pasina kusarudza mimwe michina yekugadzira maburi.
(10) Zviri nyore kutarisira. Nekuda kwehunhu hwerotary drilling rig, michina nevashandi vashoma zvinodiwa mukuvaka, uye hapana simba rakawanda rinodiwa, izvo zviri nyore kutarisira nekuchengetedza mari yekutarisira.
(11) Mutengo wakaderera, mutengo wakaderera wekudyara uye kudzoka nekukurumidza
Nekuda kwekuuya kwezvigadzirwa zvemichina yekuboora midiki inotenderera mumakore achangopfuura, mutengo wekutenga michina yekuboora pakuvaka nheyo wakaderera zvikuru. Midziyo isingasviki miriyoni imwe chete yeYuan yakatangwa imwe mushure meimwe, uye vamwe vanotoisa mari inodarika 100000 yuan kuti vave nemidziyo yavo yekuvaka.
