API Spec 5CT Seamless Tubing kav
Product Description
Cov tubing tau muab faib ua tubing tiaj tus (NU), tuab tubing (EU) thiab ib leeg tubing (I).Flat tubing txhais tau hais tias qhov kawg ntawm cov tubing yog ncaj qha threaded thiab ua ke tsis muaj thickening.Thickened tubing refers rau ob kawg tom qab sab nraud thickening, ces lub tsheb threads thiab nrog coupling.Integral jointtubing yog hais txog ib qho kawg los ntawm kev thickening ntawm sab nraud threads ntawm lub tsheb, lub othelen los ntawm sab nraud thickening ntawm cov xov sab hauv ntawm lub tsheb, ncaj qha txuas yam tsis muaj coupling.
Kev ua haujlwm ntawm tubing: roj thiab roj rho tawm: Tom qab ua tiav ntawm qhov zoo drilling thiab cementing, cov tubing cais nyob rau hauv casing ntawm lub reservoir extract roj thiab roj rau saum npoo.Kev Txhaj Tshuaj Dej: Thaum lub siab downhole tsis txaus, dej yog txhaj rau hauv lub qhov dej los ntawm lub raj.Kev Txhaj Tshuaj: Hauv cov txheej txheem ntawm cov roj hnyav thermal rov qab, cov cua sov rwb thaiv tsev tubing yog siv los nkag rau hauv chav dej.acidizing thiab fracturina media los yog cov kab taag yuav tsum tau nkag mus rau hauv lub reservoirand cov xov xwm los yog solidified tshuaj yog thauj los ntawm lub tubing.
