Raws li cov txheej txheem kev faib tawm ntawm cov tshuaj siv roj av, surfactants rau oilfield siv tau categorized los ntawm daim ntawv thov rau hauv drilling surfactants, ntau lawm surfactants, txhim khu cov roj rov qab surfactants, roj thiab roj sib sau ua ke / thauj surfactants, thiab dej kho surfactants.
Drilling Surfactantscov
Ntawm cov roj av surfactants, drilling surfactants (xws li drilling kua additives thiab cementing additives) account rau qhov loj tshaj plaws noj ntim - kwv yees li 60% ntawm tag nrho cov oilfield surfactant siv. Kev tsim cov surfactants, txawm tias me me hauv qhov ntau, yog cov thev naus laus zis ntau dua, suav txog ib feem peb ntawm tag nrho. Ob pawg no tuav qhov tseem ceeb hauv kev siv roj av surfactant.
Hauv Suav teb, kev tshawb fawb tsom mus rau ob qhov tseem ceeb: kev siv cov khoom siv raw khoom thiab tsim cov khoom siv hluavtaws tshiab (xws li monomers). Thoob ntiaj teb, kev tshawb fawb txog kev tshawb fawb txog cov dej ntxiv yog qhov tshwj xeeb tshaj plaws, hais txog sulfonic acid pab pawg uas muaj cov khoom siv hluavtaws ua lub hauv paus rau ntau yam khoom-ib qho qauv uas yuav ua rau kev txhim kho yav tom ntej. Cov kev sib tsoo tau ua nyob rau hauv cov viscosity reducers, kua dej tswj cov neeg ua haujlwm, thiab lubricants. Tshwj xeeb tshaj yog, nyob rau hauv xyoo tas los no, polymeric cawv surfactants nrog huab point teebmeem tau dav siv nyob rau hauv domestic oilfields, tsim ib tug series ntawm polymeric cawv drilling kua system. Tsis tas li ntawd, methyl glucoside thiab glycerin-raws li cov kua dej drilling tau ua pov thawj tau txais txiaj ntsig zoo hauv daim ntawv thov, ntxiv rau kev txhim kho ntawm drilling surfactants. Tam sim no, Tuam Tshoj txoj kev drilling kua additives encompass 18 pawg nrog ntau tshaj ib txhiab ntau yam, nrog rau txhua xyoo noj ze ze 300,000 tons.
Kev tsim tawm Surfactantscov
Piv rau drilling surfactants, ntau lawm surfactants muaj tsawg dua nyob rau hauv ntau yam thiab kom muaj nuj nqis, tshwj xeeb tshaj yog cov siv nyob rau hauv acidizing thiab fracturing. Hauv kev puas tsuaj surfactants, kev tshawb fawb ntawm gelling cov neeg ua haujlwm feem ntau tsom rau kev hloov kho cov pos hniav thiab cellulose, nrog rau cov khoom siv hluavtaws xws li polyacrylamide. Nyob rau hauv xyoo tas los no, thoob ntiaj teb kev nce qib hauv acidizing kua surfactants tau qeeb, nrog R & D tseem ceeb hloov mus raucorrosion inhibitorsrau acidizing. Cov inhibitors no feem ntau yog tsim los ntawm kev hloov kho lossis sib xyaw cov ntaub ntawv raw uas twb muaj lawm, nrog rau lub hom phiaj ntawm kev ua kom tsis muaj zog lossis tsis muaj tshuaj lom thiab roj / dej solubility lossis dej dispersibility. Amine-raws li, quaternary ammonium, thiab alkyne cawv sib xyaw inhibitors muaj ntau, thaum aldehyde-based inhibitors tau poob qis vim muaj kev txhawj xeeb txog toxicity. Lwm qhov kev tsim kho tshiab suav nrog dodecylbenzene sulfonic acid complexes nrog qis-molecular-yuag amines (xws li, ethylamine, propylamine, C8-18 thawj amines, oleic diethanolamide), thiab acid-hauv-roj emulsifiers. Nyob rau hauv Suav teb, kev tshawb fawb ntawm surfactants rau fracturing thiab acidizing kua tau lagged, nrog kev nce qib tsawg tshaj li corrosion inhibitors. Ntawm cov khoom muaj, amine-raws li cov tebchaw (thawj, theem nrab, tertiary, lossis quaternary amides thiab lawv cov khoom sib xyaw) ua tus thawj, ua raws li imidazoline derivatives ua lwm chav kawm loj ntawm cov organic corrosion inhibitors.
Roj thiab roj sib sau ua ke / Thauj Surfactantscov
Kev tshawb fawb thiab kev tsim cov surfactants rau roj thiab roj sib sau ua ke / kev thauj mus los hauv Suav teb tau pib xyoo 1960. Niaj hnub no, muaj 14 pawg nrog ntau pua yam khoom. Crude roj demulsifiers yog cov neeg siv ntau tshaj plaws, nrog rau kev thov txhua xyoo txog li 20,000 tons. Tuam Tshoj tau tsim tailored demulsifiers rau txawv oilfields, ntau yam uas ua tau raws li 1990s thoob ntiaj teb cov qauv. Txawm li cas los xij, ncuav cov ntsiab lus depressants, ntws txhim kho, viscosity reducers, thiab wax tshem tawm / tiv thaiv cov neeg ua haujlwm tseem txwv, feem ntau yog cov khoom sib xyaw. Cov kev xav tau sib txawv ntawm cov roj av sib txawv rau cov surfactants no ua rau muaj kev nyuaj siab thiab xav tau ntau dua rau kev tsim khoom tshiab.
Oilfield Dej Kho Dej Surfactantscov
Cov tshuaj kho dej yog ib pawg tseem ceeb hauv kev txhim kho cov roj av, nrog kev siv txhua xyoo ntau tshaj 60,000 tons - txog 40% ntawm cov uas yog surfactants. Txawm hais tias qhov kev thov ntau heev, kev tshawb fawb txog kev kho dej surfactants hauv Suav teb tsis txaus, thiab cov khoom lag luam tseem tsis tiav. Cov khoom lag luam feem ntau tau hloov kho los ntawm kev kho dej hauv kev lag luam, tab sis vim yog qhov nyuaj ntawm cov dej hauv av, lawv cov kev siv feem ntau tsis zoo, qee zaum ua tsis tau raws li qhov xav tau. Thoob ntiaj teb, flocculant txoj kev loj hlob yog qhov chaw ua haujlwm tshaj plaws hauv kev tshawb fawb txog kev kho dej surfactant, yielding ntau yam khoom, tab sis ob peb tau tshwj xeeb tsim rau oilfield wastewater kho.
