Drilling Stabilizer Downhole Khoom ntawm BHA
Drilling stabilizer yog ib qho ntawm cov khoom siv downhole siv hauv qab qhov sib dhos (BHA) ntawm ib txoj hlua xyaum.Nws mechanically stabilizes BHA nyob rau hauv lub borehole nyob rau hauv thiaj li yuav zam tsis txhob nkim sidetracking, vibrations, thiab xyuas kom meej qhov zoo ntawm lub qhov yog drilled.
Nws yog tsim los ntawm lub cev hollow cylindrical thiab stabilizing hniav, ob qho tib si ua los ntawm cov hlau muaj zog.Cov hniav tuaj yeem yog ncaj los yog spiralled, thiab yog hardfaced rau hnav tsis kam.
Ob peb hom drilling stabilizers yog siv nyob rau hauv lub oilfield niaj hnub no.Thaum cov stabilizers (tag nrho machined tawm ntawm ib daim hlau) zoo li tus qauv, lwm yam yuav siv tau, xws li:
Hloov lub tes tsho stabilizer, qhov twg cov hniav nyob rau ntawm lub tes tsho, uas yog ces screwed rau ntawm lub cev.Hom no tuaj yeem txuag tau nyiaj thaum tsis muaj chaw kho vaj tse nyob ze ntawm qhov chaw drilled thiab huab cua freight yuav tsum tau siv.
Welded hniav stabilizer, qhov twg cov hniav yog welded rau ntawm lub cev.Hom no feem ntau tsis qhia txog cov roj qhov dej vim muaj kev pheej hmoo ntawm cov hniav poob, tab sis yog siv tsis tu ncua thaum drilling qhov dej los yog ntawm cov nqi qis.
Feem ntau 2 mus rau 3 stabilizers tau haum rau hauv BHA, suav nrog ib qho saum toj no lub laum me ntsis (ze-ntsis stabilizer) thiab ib lossis ob ntawm cov tho dab tshos (txoj hlua stabilizers)
