Gel breaker imatanthawuza chinthu chomwe chingawononge kukhazikika kwa ma colloids ndikupanga ma colloids kugwa mosavuta.Njira yomwe gel breaker imagwirira ntchito pa colloid imatchedwa destabilization of the colloidal particles.Gel breaker ikhoza kugawidwa m'magulu anayi: oxidation gel breaker, encapsulated oxidized gel breaker, wamba wamba enzyme gel breaker ndi enzyme gel breaker.Zotsatirazi ndizofotokozera mwachidule mfundo za zochita zawo:
1. okosijeni gel ophwanya
Zomwe zimagwiritsidwa ntchito kwambiri ndi oxidation gel breaker ndi potaziyamu sulphate, ammonium sulphate ndi zina zotero.Popeza ntchito ya oxidizer imakhudzana ndi kutentha, pamene kutentha kwa m'deralo kumakhala kotsika kuposa 49 ° C, liwiro lake limachedwa kwambiri, ndipo choyambitsa chiyenera kuwonjezeredwa.
Pali zolakwika zambiri monga: (1) Kuchitapo kanthu mwachangu ndi fracturing fluid pa kutentha kwakukulu, kusokoneza madzi otsekemera pasadakhale ndikulephera kunyamula proppant, ndipo ngakhale kupangitsa kulephera kwa zomangamanga;(2) Ndiwopanda wapadera, ndipo amatha kuchitapo kanthu ndi zomwe zimakumana nazo, monga mapaipi, mapangidwe a matrix ndi ma hydrocarbons, kupanga zonyansa zomwe sizigwirizana ndi mapangidwe, zomwe zimayambitsa kuwonongeka kwa mapangidwe;(3) Chophwanya gel oxidation chimatha kudyedwa chisanafike pomwe chandamale, chifukwa chake sichingakwaniritse cholinga chophwanya gel.
2. encapsulated makutidwe ndi okosijeni gel osweka
Chotsekera gel osakaniza ndi chipolopolo chopangidwa chokhala ndi peroxide yokha.Pachimake chophatikizika cha oxidation gel breaker ndi chophwanya gel, chomwe chitha kusungunuka kukhala oxidant yolimba yokhala ndi zochita zambiri polumikizana ndi madzi.Ubwino wa encapsulated makutidwe ndi okosijeni wosweka gel osakaniza ndi kuchepetsa chikoka cha gel osakaniza pa rheological katundu wa fracturing madzimadzi, Kuchulukitsa kuchuluka kwa gel ophwanya wosweka ndi kusintha madutsidwe wa kuthandiza ming'alu.
3. ochiritsira enzyme gel osakaniza
Enzyme ndi puloteni yachilengedwe yokhala ndi luso lapamwamba lothandizira komanso kuchita bwino, ndipo mawonekedwe ake ndi kapangidwe kake sizisintha pakachitidwe kothandizira, kotero zimatha kuyambitsanso zina.Ochiritsira enzyme gel ophwanya wosweka ndi chisakanizo cha hemicellulase, cellulase, amylase ndi pectinase, amene sangathe amanyoza enieni ma polima ndipo sangathe kukwaniritsa abwino gel osakaniza-kuswa kwenikweni.
Kuphatikiza apo, ngakhale ochiritsira enzyme gel breaker ndi bwino fracturing madzimadzi gel osweka pa kutentha otsika, amafuna otsika pH mtengo.Nthawi zambiri, ntchito ya michere imakhala yochuluka kwambiri pamene pH = 6, ndipo kutentha kwakukulu ndi pH yamtengo wapatali kumapangitsa kuti enzyme iwonongeke.
4. enzyme gel ophwanya
Poganizira izi, dongosolo latsopano la bioenzyme degelatinization linaphunziridwanso mumtundu wake wa kutentha ndi pH, makamaka kuwunika ma hydrolases (LSE) a glycoside bond of polysaccharide polima.Amangowola zomangira zenizeni za glycoside mu kapangidwe ka ma polima a polysaccharide, ndipo amatha kusokoneza ma polima kukhala osachepetsa ma monosaccharides ndi ma disaccharides.Ma enzymes osweka gelwa makamaka amaphatikiza enzyme ya cellulose glycoside bond, wowuma wa glucoside bond yeniyeni enzyme, guanidine glucoside bond yeniyeni enzyme ndi zina zotero.
Zophulitsa ma gel ophatikizidwa omwe tapatsidwa ndi omwe angopangidwa kumene mzaka zaposachedwa.Ukadaulo wapamwamba wokutira umagwiritsidwa ntchito popanga chotchinga chotchinga pa chophwanya wamba, ndipo kuthamanga kwa gel-breaker ndikosavuta.Amagwiritsidwa ntchito kwambiri popangira madzi opangira mafuta a Wells Wells, makamaka pakuphwanyidwa kwa zitsime zamafuta apakati komanso zakuya.Zigawo zogwira ntchito za encapsulated gel breaker zimatulutsidwa ndi mapangidwe a pressure extrusion.Ubwino ndi: mkulu yogwira pophika okhutira, kumasula kwathunthu, kuchepetsa imfa yogwira zosakaniza, otsika poizoni, kuswa gel osakaniza bwino, mosavuta flowback, zochepa zotsalira.
Weifang Totpion Chemical Viwanda Co., Ltd ndi akatswirichophwanyira ma gel ophwanyidwa ndikumangitsa mabizinesi opanga zowonjezera zotulutsa zokhazikika komanso ogulitsa.Chonde pitani patsamba lathu www.toptionchem.com kuti mumve zambiri.Ngati muli ndi chofunikira chilichonse, chonde musazengereze kulumikizana nafe.
