Thickeners rau Acid Fracturing
Khoom taw qhia
Lub kaw lus muaj qhov kub thiab txias thiab ntsev tsis kam, haum rau cov pa tawg ntawm cov roj thiab cov qhov dej ntawm 60 ℃ thiab 160 ℃, tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau lub qhov dej tshaj 120 ℃. Cov txheej txheem no tuaj yeem siv nrog cov dej ntws tawm ntawm qhov chaw, thiab cov nyhuv yuav tsis cuam tshuam. UZP-160A kuj tseem tuaj yeem siv los ua tus cab reducer.
Hydraulic fracturing, tseem hu ua fracking, yog ib tug zoo stimulation txheej txheem siv los extract natural gas thiab roj los ntawm tob hauv av pob zeb formations. Cov txheej txheem no yuav tsum tau txhaj cov kua dej sib xyaw ua ke rau hauv lub qhov dej kom tsim cov pob zeb tawg, tso cai rau cov hydrocarbons ntws ntau dua thiab muab rho tawm mus rau saum npoo. Cov kua dej siv hauv hydraulic fracturing, hu ua fracturing fluid, feem ntau muaj cov dej, cov khoom siv (xws li cov xuab zeb lossis cov hlaws dai), thiab ntau yam tshuaj ntxiv, suav nrog cov kab sib txuas xws li zirconium-based compounds.
Zirconium-based crosslinking agents, lossis zirconium crosslinkers, ua lub luag haujlwm tseem ceeb hauv cov txheej txheem hydraulic fracturing los ntawm kev txhim kho kev ua haujlwm ntawm cov kua dej tawg. Cov tebchaw no yog tsim los ua kom cov viscosity thiab ruaj khov ntawm cov kua fracturing, yog li txhim kho nws lub peev xwm nqa cov khoom siv rau hauv cov pob txha tsim thiab tswj kom muaj kev ncaj ncees ntawm cov pob txha tawg. Zirconium crosslinkers ua tiav qhov no los ntawm cov txheej txheem hu ua crosslinking, qhov uas lawv tsim muaj zog, peb-seem sib txuas hauv cov kua dej, ua kom nws thickening thiab txhim kho nws lub peev xwm nqa tau.
Ib qho txiaj ntsig tseem ceeb ntawm zirconium-based crosslinking cov neeg ua haujlwm yog lawv qhov tshwj xeeb thermal stability, ua rau lawv zoo rau kev siv nyob rau hauv high-temperature downhole ib puag ncig uas feem ntau ntsib hauv cov roj thiab roj reservoirs. Lawv lub peev xwm los tswj kev ruaj ntseg thiab viscosity nyob rau hauv qhov kub siab ua kom muaj txiaj ntsig ntawm cov kua dej fracturing nyob rau hauv qhov nyuaj downhole tej yam kev mob, pab txhawb kom muaj kev vam meej zoo stimulation thiab txhim kho hydrocarbon rov qab.
Tsis tas li ntawd, zirconium crosslinkers muab cov txiaj ntsig ib puag ncig piv rau qee cov tshuaj siv hlau-raws li crosslinking agents. Lawv ib puag ncig tus phooj ywg profile, ua ke nrog lawv cov yam ntxwv ua tau zoo, ua rau lawv qhov kev xaiv zoo tshaj plaws rau kev ua haujlwm hydraulic fracturing, ua raws li kev lag luam kev ua kom pom tseeb ntawm kev ua haujlwm ruaj khov thiab muaj lub luag haujlwm.
Hauv cov ntsiab lus, zirconium-based crosslinking cov neeg ua haujlwm yog ib qho tseem ceeb rau kev ua tiav ntawm kev ua haujlwm hydraulic fracturing, pab txhawb kom muaj txiaj ntsig zoo ntawm cov roj ntsha thiab roj los ntawm subsurface formations. Lawv lub peev xwm los txhim kho kev ua tau zoo thiab kev ruaj ntseg ntawm cov kua dej tawg, ua ke nrog lawv cov thermal resilience thiab ib puag ncig kev sib raug zoo, muab lawv ua cov khoom tseem ceeb hauv cov khoom siv roj thiab roj niaj hnub. Raws li kev lag luam txuas ntxiv mus, zirconium crosslinkers yuav tsum ua lub luag haujlwm tseem ceeb hauv kev ua kom zoo dua cov txheej txheem hydraulic fracturing thiab txhawb kev txhim kho lub zog ruaj khov.
