Ua ib lub chaw tsim khoom siv pneumatic dej qhov dej drilling rig, peb nkag siab tias pneumatic dej qhov dej drilling rigs yuav tsum siv ntau txoj kev sib txawv thaum ntsib ntau txheej geological hauv cov txheej txheem drilling kom ua tiav cov txiaj ntsig zoo. Cov txheej geological sib txawv kuj yuav tsum tau ntsib, xws li txheej xuab zeb quicksand thiab txheej gypsum. Thaum gypsum nkag mus rau hauv thaum lub sijhawm drilling ntawm pneumatic dej qhov dej drilling rig, calcium ions tuaj yeem raug tshem tawm los ntawm kev koom nrog soda tshauv, calcium tshem tawm thiab viscosity txo. Lub caij no, tus neeg sawv cev viscosity-txo nrog calcium tiv thaiv muaj zog tuaj yeem siv los tswj cov viscosity-txo thiab ua rau qhov tsis txaus ntawm cov neeg sawv cev lim-poob-txo, tus neeg sawv cev tiv thaiv kev sib tsoo thiab lwm yam khoom siv.
I. Txheej Gypsum
Ua ntej tho qhov txheej gypsum, cov kua dej ntawm lub rig raug kho ua ntej kom txo cov khoom khov thiab viscosity, thiab cov neeg sawv cev kho gypsum koom nrog (piv txwv li, soda tshauv, calcium remover, viscosity reducer, thiab lwm yam). Thiab raws li cov ntaub ntawv tsim kho ntawm cov qhov dej nyob ze, cov neeg sawv cev kho rau kev kho cov txheej gypsum tau npaj ua ntej. Txhim kho tus nqi pH ntawm cov kua dej ntawm lub qhov dej drilling rig, thiab tom qab ntawd txhim kho lub peev xwm ntawm cov tshuab drilling dej me me kom tiv taus gypsum kev kis kab mob.
Qhov thib ob, txheej xuab zeb quicksand
Thaum tho qhov av xuab zeb ceev, nws yog qhov tsim nyog los txhim kho qhov viscosity ntawm cov kua dej drilling thiab cov ntsiab lus bentonite ntawm cov kua dej drilling rig drilling, uas feem ntau yuav tsum tau siab dua 10%. Txhawm rau txhim kho kev ua haujlwm ntawm phab ntsa ntawm cov kua dej drilling rig drilling, qhov kev yaig ntawm cov txheej xuab zeb ceev raug txo qis tom qab txo qhov kev hloov chaw hauv qhov project. Ua ntej pib drilling, qhov seem yuav tsum tau kaw nrog cov av nkos tuab nrog viscosity ntau dua 80 kom ntseeg tau tias qhov pib thiab nres ntawm drilling, hluav taws xob logging thiab casing ntawm cov tshuab drilling dej me me.
III. Pob zeb xuab zeb quartz
Yog tias cov xuab zeb xuab zeb yog pob zeb tawv heev, feem ntau qhov kev nce qib ntawm kev khawb av yuav tshwm sim qeeb. Thaum khawb ib 'meter', tej zaum yuav muaj xuab zeb ob meters, cov cuab yeej khawb av dhia ceev ceev, ntau cov slag txiav thiab faus cov qhov tsis zoo ntawm kev khawb av. Yog li ntawd, yuav tsum nkag siab txog thaj av kom meej.
Cov dej ntshiab tsis muaj lubricity zoo li cov av nkos, thiab cov cuab yeej drilling hauv cov pob zeb tawv dhia ntau heev ua rau cov pob zeb tawg thaum cov cuab yeej drilling dhia; dej ntshiab muaj cov khoom loj heev, thiab cov kua dej ntws tsis tuaj yeem nqa cov pob zeb loj zuj zus tawm ntawm lub qhov. Cov pob zeb me me zoo li xuab zeb tseem ntab thiab poob rau hauv lub qhov. Yog tias siv lub raj rho hmoov, ib lossis ob meters ntawm cov xuab zeb yuav raug drilling. Kev tsis saib xyuas me ntsis yuav faus lub laum, thiab ntau xuab zeb yuav ua rau muaj teeb meem ntau dua hauv kev tshem lub qhov.
Cov xuab zeb thaum lub sijhawm thov yog tsim los ntawm kev tso dej thiab yog pob zeb tawv heev. Lub tshuab me me pneumatic dej zoo drilling rig rau hauv qhov thaum drilling qhov yog qhov ntiav heev (303354200 m), yog li kev siv dav dav ntawm pob zeb diamond laum ntsis drilling dej ntshiab, tsis siv neeg slurry, feem ntau pom hauv cov yeeb yaj kiab drilling qeeb, ib 'meter' ntawm cov yeeb yaj kiab drilling yuav qhia ob 'meter' ntawm xuab zeb, cov cuab yeej drilling dhia loj, slag, pob zeb chipped ntau dua, drilling tsis ua haujlwm faus thiab lwm yam.
Kev daws teeb meem: Yog tias kev khawb av nkos tsis pheej yig, koj tuaj yeem txo qhov tshwm sim ntawm cov xuab zeb los ntawm kev txiav cov dej me me uas dhia, koj tuaj yeem ntxiv cov nitro acid thiab alkali additives hauv dej los ua lub luag haujlwm ntawm kev co damping lubrication, yog li koj tuaj yeem txo qhov ntau ntawm cov rigs dhia thiab xuab zeb, thiab tom qab ntawd ua raws li kev ntxuav cov qhov drilling ntawm cov dej pneumatic drilling rigs, thiab thaum kawg daws qhov teeb meem!
