Insulated Yeeb Nkab
Insulated roj raj yog ob-txheej concentric kab, nrog rau annular qhov chaw ntawm ob txheej ntawm cov hlab ntim nrog adiabatic khoom, inert gas los yog lub tshuab nqus tsev vacuum.
Kev ua tiav peb qhov kev siv hluav taws xob tseem ceeb ntawm lub tshuab nqus tsev nqus, kev xav txog kev kub ntxhov thiab cov cua sov convection thaiv, qhov kev ua tau zoo ntawm cov hluav taws kub-insulating ntawm cov hluav taws kub-insulating roj yeeb nkab yog tsim. Nws txo cov cua sov poob ntawm chav txhaj tshuaj, txhim kho qhov tob tob thiab chav qhuav ntawm cov dej tso dej; txo cov thermal stress ntawm casing thiab cement nplhaib los tiv thaiv kub kub puas ntawm casing; thiab txo cov cua sov poob hauv cov txheej txheem ntawm cov roj crude lifting. Feem ntau siv nyob rau hauv tuab roj thermal rov qab (steam throughput), SAGD expansion rau brine extraction, nto tsheb thauj mus los, geothermal extraction thiab hais txog.
