I-gel breaker ibhekisela kumkhiqizo ongacekela phansi ukuzinza kwama-colloid futhi wenze ama-colloid awe kalula.Inqubo lapho i-gel breaker isebenza khona ku-colloid ibizwa ngokuthi ukuchithwa kwezinhlayiya ze-colloidal.I-gel breaker ingahlukaniswa ngezigaba ezine: i-oxidation gel breaker, i-encapsulated oxidized gel breaker, i-enzyme evamile ye-gel breaker kanye ne-enzyme ethize yejeli.Okulandelayo isingeniso esifushane somgomo wesenzo sabo:
1. ijeli ye-oxidation breaker
Ijeli ye-oxidation esetshenziswa kakhulu yi-potassium persulphate, ammonium persulphate nokunye.Njengoba umsebenzi we-oxidizer uhlobene nezinga lokushisa, lapho izinga lokushisa lesendlalelo sendawo ngokuvamile lingaphansi kuka-49 ° C, isivinini saso sokusabela sihamba kancane, futhi isisebenzi sidinga ukungezwa.
Kunokukhubazeka okuningi okufana nalokhu: (1) Ukusabela ngokushesha ngoketshezi oluqhekekayo ekushiseni okuphezulu, ukwehlisa isithunzi se-fracturing fluid kusengaphambili futhi ulahlekelwe amandla okuthutha i-propant, futhi kuholele ngisho nasekuhlulekeni kokwakhiwa kwe-fracturing;(2) Kuyi-reactant engakhethekile, futhi ingasabela nganoma iyiphi i-reactant ehlangatshezwane nayo, njengamapayipi, i-matrix yokwakha nama-hydrocarbon, ekhiqiza ukungcola okungahambisani nokwakheka, okubangela ukulimala kokwakheka;(3) Ijeli ye-oxidation breaker kungenzeka idliwe ngaphambi kokuba ifinyelele umfantu ohlosiwe, ngakho ayikwazi ukufeza inhloso yokuphula ijeli.
2. ijeli ye-oxidation encapsulated
I-encapsulated gel breaker igobolondo lokwenziwa eliqukethe i-peroxide kuphela.Impahla ewumgogodla ye-encapsulated oxidation gel breaker i-gel breaker, engancibilika ibe i-oxidant eqinile eqinile enomsebenzi ophezulu ngokuthintana namanzi.Inzuzo ye-encapsulated oxidation gel breaker ukunciphisa ithonya le-gel breaker ezindaweni ze-rheological of fracturing fluid, Khulisa inani le-gel breaker futhi uthuthukise ukuqhutshwa kwemifantu esekelayo.
3. ezejwayelekile enzyme gel breaker
I-Enzyme iyiphrotheni yebhayoloji enekhono eliphezulu le-catalytic kanye nomsebenzi omuhle, futhi isimo sayo nesakhiwo akuguquki ngesikhathi sokusabela kwe-catalytic, ngakho-ke ingadala okunye ukusabela.I-enzyme evamile ye-gel breaker iyingxube ye-hemicellulase, i-cellulase, i-amylase ne-pectinase, engakwazi ukuthunaza ama-polymers athile futhi engakwazi ukufeza umphumela omuhle wokuphulwa kwejeli.
Ukwengeza, nakuba i-enzyme evamile yokuphumula ijeli iyi-jel breaker engcono ye-fracturing emazingeni okushisa aphansi, idinga inani eliphansi le-pH.Ngokuvamile, ukusebenza kwama-enzyme kuphezulu uma i-pH=6, futhi izinga lokushisa eliphezulu kanye nenani le-pH ephezulu kuzobangela ukuba i-enzyme ilahlekelwe umsebenzi.
4. i-enzyme ethile ye-gel breaker
Ngenxa yalokhu, uhlelo olusha olukhethekile lwe-bioenzyme degelatinization luphinde lwacwaningwa ebangeni lokushisa lokusetshenziswa kwalo kanye nebanga le-pH, ikakhulukazi ukuhlola ama-hydrolases athile (LSE) amabhondi e-glycoside ama-polysaccharide polymers.Zibola kuphela izibopho ezithile ze-glycoside esakhiweni sama-polysaccharide polymers, futhi zingehlisa izinga lama-polymers abe ama-monosaccharides anganciphisi nama-disaccharides.Lawa ma-enzyme athile aphula ijeli ikakhulukazi ahlanganisa i-enzyme ethize ye-cellulose glycoside bond, i-enzyme ethize ye-starch glucoside bond, i-enzyme ethize ye-guanidine glucoside bond nokunye.
Iziqephu zejeli ezihlanganisiwe ezinikezwe yithi ziyimikhiqizo emisha eyenziwe eminyakeni yakamuva.Ubuchwepheshe bokunamathela obuthuthukisiwe busetshenziselwa ukukhiqiza isendlalelo sokuzivikela ku-gel breaker evamile, futhi isivinini sokuphulwa kwejeli siyalawuleka.Isetshenziswa kakhulu ekuqhekekeni okusekelwe emanzini ku-oyela Wells, ikakhulukazi ekuqhekekeni kwama Wells kawoyela aphakathi nendawo najulile.Izingxenye ezisebenzayo ze-encapsulated gel breaker zikhishwa yi-extrusion yokucindezela kokubunjwa.Izinzuzo yilezi: okuqukethwe okuphezulu kwesithako esisebenzayo, ukukhulula ngokuphelele, ukunciphisa ukulahlekelwa kwezithako ezisebenzayo, ubuthi obuphansi, i-gel iphule kahle, i-flowback elula, izinsalela ezincane.
