Muaj nyob rau hauv ob qho tib si ncaj hniav thiab helical hniav configurations,nruj centralizersyog ib qho cuab yeej tseem ceeb rau kev ua kom cov dej ntws zoo tshaj plaws hauv kev siv kab rov tav.Cov nocentralizersyog tsim los nrog cov txheej txheem ntawm lub xeev-ntawm-tus-kos duab, kom ntseeg tau tias lawv tuaj yeem tiv taus qhov cuam tshuam thiab hnav thaum tswj kev ncaj ncees txawm tias nyob rau hauv qhov kub thiab txias.
Cov hniav ncaj tsim ntawm cov centralizers no muab cov kua dej zoo heev rau kev ua kom zoo, cov kua dej ntws tawm hauv lub qhov dej.Qhov kev tsim no txo qhov kev pheej hmoo ntawm cov kua dej bypass, txhawb nqa cov borehole tshem tawm thiab zoo dua av nkos.Tsis tas li ntawd, txoj kev ncaj hniav tsim pab tiv thaiv qhov sib txawv daig tubing, txhim kho tag nrho cov txheej txheem drilling.
Ntawm qhov tod tes, txoj cai helical hniav tsim txhim kho cov kua dej turbulence, tsim kom muaj cov nyhuv vortex uas pab txhawb cov av nkos thiab cov dej hloov pauv.Qhov kev tsim no muaj txiaj ntsig tshwj xeeb yog qhov yuav tsum tau muaj cov kua dej sib xyaw zoo, xws li hauv cov qhov dej sib txawv lossis thaum drilling los ntawm cov txheej txheem heterogeneous heev.Lub helical hniav tsim kom paub meej qhov sib txawv ntawm qhov sib txawv, txo qhov kev pheej hmoo ntawm kev sib txawv ntawm qhov sib txawv, thiab txhim kho qhov zoo ntawm qhov zoo.
Cov nonruj centralizersyog tsim rau ob qho tib si ntsug thiab kab rov tav qhov dej, ua rau lawv muaj ntau yam cuab yeej hauv ntau hom kev siv drilling.Txawm hais tias ua haujlwm ntawm ntug dej lossis xaiv qhov chaw nyob sab nraud, cov chaw nruab nrab no muab kev ua tau zoo thiab kev ntseeg siab.
Qhov nocentralizersqauv tso cai rau yooj yim installation minimizing tus neeg teb xov tooj lub sij hawm thiab maximizing efficiency.Tsis tas li ntawd, cov khoom siv muaj tshuaj lom neeg zoo heev, ua rau cov khoom siv hauv nruab nrab no haum rau ntau yam ntawm cov dej drilling thiab cov dej hauv qhov dej.
Hauv kev xaus, kev sib xyaw ua ke ntawmnruj centralizersnrog ncaj thiab sab tes xis helical hniav tsim tsim kom muaj hydrodynamics thiab ua kom cov borehole txav tau zoo thiab cov av nkos.Txawm ua hauj lwm onshore los yog offshore, cov nocentralizersyog cov cuab yeej txhim khu kev qha uas txhim kho drilling efficiency thiab tag nrho zoo zoo.
