Slotted casing yog txheej txheem ntau lawm thiab cov khoom hauv cov ntxaij vab tshaus roj av. Lub ntsiab tsis zoo ntawm slotted casing muaj xws li cov khoom, phab ntsa thickness, txoj kab uas hla, tus naj npawb ntawm slits, slit specifications thiab screen ntev.
Cov khoom siv raw ntawm slotted casing yog petroleum casing. Yeej, roj av casing yog siv los ua cov khoom siv los tsim thiab txheej txheem slotted casing. Muaj ntau ntau hom kev npaj ntawm slotted casing. Cov feem ntau yog cov kab sib txuas, pawg casing cross thiab cross casing. Lub verticality ntawm ntug ntawm lub slit yog zoo heev, ntug yog txiav heev smoothly, tsis muaj burr, thiab lub slit yog txawm. Slotted casing yuav tsim ib txheej tiv thaiv heev nyob rau saum npoo ntawm lub vijtsam raj thaum lub sij hawm tag nrho kev tiv thaiv corrosion. Nrog kev tiv thaiv ntawm cov txheej txheem tiv thaiv no, kev tiv thaiv corrosion thiab kev ua haujlwm ntawm lub vijtsam raj tau zoo heev. , tuaj yeem txuas ntxiv lub neej kev pab cuam ntawm slotted casing nyob rau hauv underground roj drilling ua hauj lwm, yog li txo nqi noj. Thaum tshem tawm cov roj, kev siv cov slotted casing tuaj yeem lim cov xuab zeb thiab plua plav, txo tus nqi txij nkawm los ntawm 80%, thiab txhim kho kev ruaj ntseg, txuas ntxiv thiab lub zog ntawm lim xuab zeb thiab plua plav, uas zoo heev txhim kho kev ua haujlwm. . Yog li ntawd, vim hais tias ntawm cov dej num thiab cov yam ntxwv ntawm slotted casing, koj yuav tsum tau them tshwj xeeb mloog thaum muas roj cov ntxaij vab tshaus, thiab nws kuj yog ib tug txheej txheem uas manufacturers muab tseem ceeb heev rau.
Hauv kev ua haujlwm ntawm cov roj drilling, cov raj tshuaj ntsuam yog ib qho tseem ceeb ntawm cov cuab yeej siv thiab feem ntau siv rau kev ua tiav thaum ntxov lossis roj av tswj cov xuab zeb. Tam sim no, feem ntau siv tshuaj ntsuam raj yog roj av slotted screen raj. Txoj kev tsim khoom ntawm hom kev tshuaj ntsuam lub raj no yog: winding ib tug hlau hlau ntawm ib tug ntoo khaub lig-section ntawm ib tug hlau liner tusyees faib nyob rau hauv ib ncig ntawm lub screen tuav los yog qhib thiab welding nws ruaj khov, tawm hauv qhov sib txawv raws li lub qhov screen. Txawm hais tias txoj kev tsim khoom no tau siv dav, muaj qee qhov teeb meem thaum lub vijtsam zoo li no tau qis dua rau hauv qhov dej. Thaum nws raug yuam los ntawm qhov nkhaus ntawm qhov sib txawv ntawm qhov dej los yog kab rov tav, nws yuav tsis muaj kev sib tsoo nrog thiab nyem cov phab ntsa zoo los yog casing. Vim lub siab thiab kev sib txhuam, tangled threads yog nquag tshwm sim, ua rau lub vijtsam raj puas lossis qhov sib txawv deformation, ua rau txo qhov ua tiav zoo thiab cov xuab zeb tswj cov nyhuv lossis tsis ua haujlwm. Yuav kom daws tau qhov tsis txaus ntawm qhov slotted casing, slotted screen raj nrog cov kav dej sib xyaw thiab cov seams tau tshwm sim. Vim nws qhov kev ua tau zoo thiab tus nqi qis, cov yeeb nkab slotted tau txais txiaj ntsig zoo los ntawm cov roj av loj thiab dav siv sai li sai tau. Nws tuaj yeem pom tau tias qhov tshwm sim ntawm slotted casing muab cov khoom siv rau kev txhim kho cov kab rov tav qhov dej thiab cov qhov dej ntws tawm thiab cov roj rho tawm hauv cov xuab zeb siab.
