Ndeipi mhinduro inoshanda pakuchera mugodhi?

Mumigodhi, kuvaka tsime remvura, kuongorora geological uye mamwe mapurojekiti einjiniya,drill rodsndizvo zvakakosha zvikamu zvinobatanidza rigi dzekuchera uye mabhiti ekuboorera. Simba ravo, kurongeka uye kuchinjika kwakanangana nekuita basa rekuchera, kuchengetedzwa kwekuvaka uye hupenyu hwebasa. DRILLMORE inotarisa paR&D nekugadzira maturusi ekuchera matombo, kutanga mana akateedzana ezvibooresa zvemamiriro akasiyana ekushanda, achifukidza huwandu hwakazara hwezviitiko kubva kune isina kudzika kusvika kumakomba akadzika, kuchera kwakajairwa kudzoreredza kutenderera kutenderera, kupa yakagadzikana uye yakavimbika yekuchera rutsigiro rwekuvaka engineering.

Tri-cone drill rods ndiwo musimboti wemagetsi zvikamu zvemahombe ekuchera, akagadzirirwa zvakana-i-gomba kuchera nekuomarara kwepamusoro, kusimba kwesimba rekudzivirira uye hupenyu hurefu hwebasa. Nekunze dhayamita kubva 146mm kusvika 273mm, ivo vanowirirana neakasiyana-siyana akabatanidzwa kubva ku4"BECO kusvika 8"BECO, uye hurefu hunobudirira hunogona kusvika ku10668mm. Yakagadzirwa nemhando yepamusoro-yemhando yemhando yemhando yekupisa neyakasanganiswa kupisa kurapwa, iwo tambo dzakanyatsogadzirwa-muchina neCNC uye inoongororwa nehunyanzvi geji, kuve nechokwadi chekubatikana kwakasimba uye kugadzikana kwakanyanya kutapurirana torque. Iwo anoshandiswa zvakanyanya mumapurojekiti makuru ekuchera akadai semigodhi, matsime emvura uye geothermal simba.

Mvura yemvura yekuchera tsvimbo inogadzirirwa tsime remvura uye geothermal tsime kusimudzira, yakakodzera kushanda pakadzika kwemamita 200-1500. Nemadhayamita ekunze kubva pa76mm kusvika 114mm, anofananidza majoini akajairwa seAPI 2 3/8REG uye NC26. Muviri wepombi wakagadzirwa nesimbi yemhando yepamusoro-soro, uye tsvimbo inopera inogumburwa nepakati-frequency kupisa kuwedzera nzvimbo yewelding. Mushure mekupokana welding, kupisa kurapwa kunoitwa kuti ive nechokwadi chekusimba kweweld. Inoratidzira yakaderera kutenderera torque, kushoma kupikisa uye kuita kwakanaka kwekuisa chisimbiso, ivo vanosangana nezvinodiwa zvese zviri zviviri mvura uye gasi kuchera, zvakanyanya kuvandudza kushanda kwekuvaka kwetsime remvura.

Yakabatanidzwa migodhi yekubooresa tsvimbo inobatanidza kuchera uye magetsi ekufambisa mabasa, akakodzera yakazara-hydraulic yakavhurika-gomba rigs, crawler DTH rigs nemimwe michina. Kutora tekinoroji yekugadzira kana friction welding tekinoroji, yakasanganiswa nesimbi-yakasimba alloy simbi uye kudzima uye kupisa kupisa kurapwa, vane kuneta kwakanyanya uye kukanganisa kuramba. Nekunze kwemadhayamita kubva 64mm kusvika 127mm, vanotsigira API mwero uye BECO majoini, ane hurefu hunoshanda hwe3000-6000mm. Izvo zvakakodzerwa nemamiriro ekushanda akaoma senge maburi ekuputika, maburi ekumisikidza uye maburi ekuongorora geological, uye anogona kushanda zvakatsiga kwenguva yakareba munzvimbo dzakaoma.

Reverse circulation drill rods inotora dhizaini yemhando mbiri-chani, kuona panguva imwe chete yepakati slag discharge uye annulus gasi jekiseni, zvinobudirira kubvisa kusvibiswa kwepakati, kunamatira uye kurasikirwa matambudziko. Iine sampling kuperera inopfuura 95% uye 40% kuwedzera kwekuita basa rekuchera, ndiyo sarudzo yakanaka yekuongorora zvicherwa, geothermal uye coalbed methane matsime. Iine madhayamita ekunze kubva pa89mm kusvika 127mm, anowirirana neRemet uye API akajairwa majoini, ane customizable madziro ukobvu uye akavimbika emukati uye ekunze chubhu zvisimbiso, zvikuru kuderedza kuvaka uye njodzi.
