Yam tseem ceeb ntawm Gel Breaker

Gel breaker hais txog cov khoom uas tuaj yeem rhuav tshem qhov ruaj khov ntawm colloids thiab ua kom cov colloids poob yooj yim.Cov txheej txheem uas cov gel breaker ua rau lub colloid yog hu ua lub destabilization ntawm cov colloidal hais.Gel breaker tuaj yeem muab faib ua plaub pawg: oxidation gel breaker, encapsulated oxidized gel breaker, pa enzyme gel breaker thiab tshwj xeeb enzyme gel breaker.Cov hauv qab no yog cov lus qhia luv luv rau lub hauv paus ntsiab lus ntawm lawv qhov kev ua:

1. oxidation gel breaker

Feem ntau siv oxidation gel breaker yog potassium persulphate, ammonium persulphate thiab lwm yam.Txij li thaum cov kev ua ntawm oxidizer muaj feem xyuam rau qhov kub thiab txias, thaum lub hauv paus txheej txheej kub yog feem ntau qis dua 49 ° C, nws cov tshuaj tiv thaiv ceev qeeb heev, thiab cov activator yuav tsum tau ntxiv.

Muaj ntau yam tsis xws luag xws li: (1) React sai nrog fracturing kua ntawm qhov kub thiab txias, degrade fracturing kua ua ntej thiab poob peev xwm thauj proppant, thiab txawm ua rau fracturing kev tsim kho tsis ua hauj lwm;(2) Nws yog ib qho uas tsis yog tshwj xeeb reactant, thiab tuaj yeem cuam tshuam nrog txhua qhov reactant ntsib, xws li cov kav dej, tsim matrix thiab hydrocarbons, tsim cov pa phem uas tsis sib haum nrog kev tsim, ua rau kev puas tsuaj;(3) Lub oxidation gel breaker yuav tsum tau noj ua ntej mus txog lub hom phiaj tawg, yog li nws tsis tuaj yeem ua tiav lub hom phiaj ntawm kev tawg cov gel.

2. encapsulated oxidation gel breaker

Encapsulated gel breaker yog lub plhaub hluavtaws uas muaj peroxide ib leeg.Cov khoom tseem ceeb ntawm lub encapsulated oxidation gel breaker yog gel breaker, uas tuaj yeem yaj mus rau hauv cov khoom muaj zog oxidant nrog kev ua haujlwm siab los ntawm kev sib cuag nrog dej.Qhov kom zoo dua ntawm encapsulated oxidation gel breaker yog txo cov kev cuam tshuam ntawm cov gel breaker ntawm cov khoom rheological ntawm fracturing kua, nce tus nqi ntawm gel breaker thiab txhim kho cov conductivity ntawm kev txhawb cov kab nrib pleb.

3. pa enzyme gel breaker

Enzyme yog cov protein ntau uas muaj peev xwm catalytic siab thiab ua haujlwm zoo, thiab nws cov qauv thiab cov qauv tsis hloov thaum lub sij hawm catalytic cov tshuaj tiv thaiv, yog li nws tuaj yeem ua rau lwm cov tshuaj tiv thaiv.Pa enzyme gel breaker yog sib xyaw ntawm hemicellulase, cellulase, amylase thiab pectinase, uas tsis tuaj yeem degrade cov polymers tshwj xeeb thiab tsis tuaj yeem ua tiav qhov zoo tagnrho gel-tawg nyhuv.

Tsis tas li ntawd, txawm hais tias cov pa enzyme gel breaker yog qhov zoo dua cov kua dej gel breaker ntawm qhov kub thiab txias, nws yuav tsum muaj pH qis dua.Feem ntau, kev ua haujlwm ntawm cov enzymes yog qhov siab tshaj plaws thaum pH = 6, thiab qhov kub thiab txias thiab pH siab yuav ua rau cov enzymes poob haujlwm.

4. tshwj xeeb enzyme gel breaker

Raws li qhov no, qhov tshiab tshwj xeeb bioenzyme degelatinization system tau kawm ntxiv hauv nws daim ntawv thov kub thiab pH ntau yam, feem ntau tshuaj xyuas cov hydrolases (LSE) rau glycoside bonds ntawm polysaccharide polymers.Lawv tsuas yog decompose tej glycoside bonds nyob rau hauv cov qauv ntawm polysaccharide polymers, thiab degrade polymers rau hauv uas tsis yog-txo monosaccharides thiab disaccharides.Cov gel-breaking enzymes tshwj xeeb no feem ntau suav nrog cellulose glycoside daim ntawv cog lus tshwj xeeb enzyme, starch glucoside daim ntawv cog lus tshwj xeeb enzyme, guanidine glucoside daim ntawv cog lus tshwj xeeb enzyme thiab lwm yam.

Lub encapsulated gel breakers muab los ntawm peb yog cov khoom tsim tshiab hauv xyoo tas los no.Cov txheej txheem txheej txheem siab heev yog siv los tsim cov txheej txheem tiv thaiv ntawm cov gel sib tsoo, thiab cov gel tawg ceev yog tswj tau.Nws yog tsuas yog siv nyob rau hauv dej-raws li fracturing ntawm roj Wells, tshwj xeeb tshaj yog nyob rau hauv fracturing ntawm nruab nrab thiab tob roj Wells.Cov khoom siv tau zoo ntawm lub tshuab encapsulated gel breaker raug tso tawm los ntawm kev tsim siab extrusion.Qhov zoo yog: muaj cov khoom muaj txiaj ntsig siab, tso tawm tag nrho, txo qhov poob ntawm cov khoom xyaw nquag, tsis muaj tshuaj lom, tawg gel kom huv si, yooj yim flowback, tsawg residue.
