Sezvo isu tose tinoziva, kusarudzwa kwezvikamu zvakakosha zve rotary drilling rig inogadzirisa zvakananga hupenyu hwayo hwebasa. Kune izvi, Sinovo, inogadzira rotary drilling rig, inosuma nzira yekusarudza mabhaketi ekuchera.
1. Sarudza mabhakiti ekuchera maererano nemamiriro e geological
Basa guru reRotary drilling rigndiko kugadzira gomba pamusoro, uye chinhu chinoshanda idombo. Nekuda kwehudiki hudiki hwegomba remurwi rakavakwa, dombo rakaita shanduko dzakaoma muchimiro, saizi yechikamu, porosity, simende, kuitika uye simba rekumanikidza kuburikidza ne tectonic kufamba uye yakasikwa mechanical uye kemikari kuita, saka chinhu chinoshanda cheiyo rotary drilling rig. yakanyanya kuoma.
Kupedzisa, pane zvikamu zvinotevera.
Maererano ne lithology, yakakamurwa kuva shale, sandstone, limestone, granite, nezvimwe.
Maererano ne genesis, inogona kukamurwa kuva magmatic rock, sedimentary rock uye metamorphic rock;
Zvinoenderana neiyo mechanical properties, yakakamurwa kuva yakasimba, plastiki uye yakasununguka. Saka sei kusarudza drill bit zvinoenderana nemamiriro ekuumbwa? Iyi inotevera mutsara wakasarudzika:
(1) Clay: bhakiti rekuchera rinotenderera rine-single-layer pasi rinosarudzwa. Kana iyo dhayamita iri diki, bhaketi mbiri kana bhakiti rekuchera ine ndiro yekudzikisa inogona kushandiswa.
(2) Madhaka, isina kusimba yakabatana yevhu, ivhu rejecha uye hurungudo isina simende uye diki diki saizi inogona kuve yakashongedzerwa nekaviri pasi bhakiti rekuchera.
(3) Hard mastic: bhakiti rekuchera rinotenderera rine ivhu rimwechete rinopinza (rimwe uye kaviri pasi) kana siruu yakatwasuka ine mazino emugomo ichasarudzwa.
(4) Permafrost layer: yakatwasuka auger bucket nerotary bhaketi rekuchera rinogona kushandiswa kune avo vane aizi shoma, uye conical auger bit inogona kushandiswa kune avo vane hombe ice content. Izvo zvinofanirwa kucherechedzwa kuti auger bit inoshanda kune ivhu layer (kunze kwesludge), asi inofanirwa kushandiswa pasina mvura yepasi kudzivirira jamming inokonzerwa nekukweva.
(5) hurungudo nematombo akaiswa simende uye matombo akaomeswa nemhepo: conical spiral bit uye kaviri pazasi rotary bhakiti rekuchera richange rakashongedzerwa (chiteshi chimwe chete chehukuru hukuru uye chiteshi chechipiri chehukuru diki)
(6) Stroke Bedrock: ine pick barrel coring bit - conical spiral bit - rotary bhaketi rekuchera rine mbiri pasi, kana nhonga yakatwasuka spiral bit - rotary bhaketi rekuchera rine kaviri pasi.
(7) Dombo rakanyura zvishoma: rine cone barrel coring bit - conical spiral bit - kaviri pazasi rotary bhakiti rekuchera. Kana iyo dhayamita yakakurisa, graded drilling process inogamuchirwa.
