Nyob rau hauv cov roj drilling sector, polyurethane yog siv rau ntau lub hom phiaj vim nws tshwj xeeb txhua yam khoom, durability, thiab tshuaj tsis kam. Nyob rau hauv qhov xav tau tshaj plaws drilling daim ntaub ntawv, polyurethane yog unmatched nyob rau hauv cov roj drilling kev lag luam.
- Piv txwv ntawm coiled tubing stripper roj hmab, uas tshem tawm cov av nkos thiab cov kua dej los ntawm cov yeeb nkab laum raws li nws tau rub tawm ntawm qhov bore-qhov.
Cov cuab yeej Downhole:
Polyurethane yog siv los tsim cov cuab yeej downhole, xws li laum khoom, stabilizers, thiab reamers. Cov cuab yeej no raug rau cov xwm txheej hnyav, xws li kev kub siab, kub siab, thiab qhov chaw abrasive. Polyurethane muaj kev hnav zoo heev thiab kev ruaj ntseg kub, ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev tsim cov cuab yeej no. Tsis tas li ntawd, polyurethane muaj qhov ua haujlwm zoo thiab muaj cov khoom ua haujlwm poob siab zoo, uas pab txo qhov hnav thiab tsim kua muag ntawm cov khoom siv drilling.
Centralizers:
Polyurethane yog siv los tsim cov khoom siv hauv nruab nrab uas siv los khaws cov yeeb nkab hauv qhov chaw hauv qhov borehole thaum lub sijhawm drilling. Centralizers yog cov khoom tseem ceeb hauv cov txheej txheem drilling, vim tias lawv pab tiv thaiv lub casing los ntawm kev daig thiab pab txhawb kev cementing kom zoo. Polyurethane centralizers muab superior hnav tsis kam, siab-kub stability, thiab tshuaj lom neeg zoo heev, ua rau lawv zoo tagnrho rau siv nyob rau hauv hnyav drilling ib puag ncig.
Kev tiv thaiv yeeb nkab:
Polyurethane yog siv los tiv thaiv cov kav dej los ntawm corrosion thiab mechanical puas thaum lub sij hawm drilling. Polyurethane coatings muab cov txheej txheem ruaj khov thiab ntev ntev tiv thaiv kev puas tsuaj thiab cuam tshuam. Tsis tas li ntawd, polyurethane txheej muaj cov tshuaj tiv thaiv zoo heev, ua rau lawv zoo tagnrho rau kev siv hauv cov kav dej uas thauj cov kua dej corrosive.
Fracturing:
Polyurethane yog siv nyob rau hauv hydraulic fracturing ua hauj lwm los tsim cov ntsaws ruaj ruaj thiab thaiv uas tiv thaiv cov fracturing kua los ntawm kev khiav mus rau hauv ib puag ncig pob zeb formations. Polyurethane foams yog txhaj rau hauv lub qhov dej los tsim ib qho kev thaiv uas pab coj cov dej tawg mus rau lub hom phiaj pob zeb tsim. Tsis tas li ntawd, polyurethane yog siv los tsim cov khoom siv, uas yog cov khoom me me uas sib xyaw nrog cov kua fracturing los tuav qhib cov pob zeb tawg thiab tso cai rau cov roj thiab roj ntws.
Polyurethane yog cov khoom siv ntau yam uas muaj ntau yam kev siv hauv kev lag luam roj thiab roj. Hauv cov roj drilling, nws yog siv los tsim cov cuab yeej downhole, centralizers, yeeb nkab tiv thaiv, thiab hauv hydraulic fracturing ua haujlwm. Polyurethane muaj superior hnav tsis kam, siab-kub stability, zoo heev tshuaj tiv thaiv, thiab zoo poob siab absorbing zog, ua rau nws yog ib qho zoo tagnrho cov ntaub ntawv rau siv nyob rau hauv hnyav drilling ib puag ncig. Kev siv cov polyurethane hauv cov roj drilling tau ua rau kev txhim kho drilling efficiency, txo downtime, thiab nce kev nyab xeeb, ua rau nws yog ib qho tseem ceeb ntawm cov khoom siv roj thiab roj.
