Ụdị isi nke Gel Breaker

Gel breaker na-ezo aka na ngwaahịa nwere ike ibibi nkwụsi ike nke colloid ma mee ka colloid dapụ ngwa ngwa.Usoro nke onye na-agbaji gel na-arụ ọrụ na colloid bụ ihe a na-akpọ nkwụsịtụ nke mkpụrụ ndụ colloidal.Enwere ike kewaa gel breaker ụzọ anọ: oxidation gel breaker, encapsulated oxidized gel breaker, gel breaker enzyme omenala na kpọmkwem enzyme gel breaker.Ihe na-esonụ bụ mmalite mmalite nke ụkpụrụ omume ha:

1. oxidation gel breaker

Gel breaker oxidation a na-ejikarị bụ potassium persulphate, ammonium persulphate na ndị ọzọ.Ebe ọ bụ na ọrụ nke oxidizer na-ejikọta ya na okpomọkụ, mgbe oyi akwa oyi akwa na-adịkarị ala karịa 49 Celsius C, ọsọ mmeghachi omume ya na-adị ngwa ngwa, na onye na-arụ ọrụ kwesịrị ịgbakwunye ya.

Enwere ọtụtụ ntụpọ dị ka: (1) Mee ngwa ngwa na mmiri na-agbaji na oke okpomọkụ, na-eweda mmiri na-agbaji agbaji tupu oge eruo ma hapụ ikike ibufe proppant, na ọbụna na-eduga n'ịkụji ihe owuwu ụlọ;(2) Ọ bụ onye na-abụghị pụrụ iche reactant, na nwere ike meghachi omume na ihe ọ bụla reactant zutere, dị ka ọkpọkọ, formation matrix na hydrocarbons, na-amụba mmetọ ndị na-ekwekọghị na nguzobe, na-akpata mmebi;(3) O yikarịrị ka a ga-eri ihe na-agbaji gel oxidation tupu ya erute ebe a na-achọsi ike, n'ihi ya, ọ pụghị imezu nzube nke imebi gel.

2. encapsulated oxidation gel breaker

Ihe na-agbaji gel mkpuchi bụ shei sịntetik nwere peroxide naanị.Ihe bụ isi nke ihe mkpuchi oxidation gel breaker bụ onye na-agbaji gel, nke nwere ike ịgbaze n'ime oxidant siri ike nke nwere nnukwu ọrụ site na ịkpọtụrụ mmiri.Uru nke onye na-agbaji gel oxidation encapsulated bụ iji belata mmetụta nke onye na-agbaji gel na njirimara rheological nke mmiri na-agbaji, mee ka ọnụọgụ gel na-abawanye ma melite conductivity nke na-akwado cracks.

3. ot enzyme gel breaker

Enzyme bụ protein dị ndụ nke nwere ikike catalytic dị elu na ezigbo ọrụ, na ụdị ya na nhazi ya adịghị agbanwe n'oge mmeghachi omume catalytic, ya mere ọ nwere ike ime ka mmeghachi omume ọzọ pụta.Gel breaker enzyme nke na-eme ihe bụ ngwakọta nke hemicellulase, cellulase, amylase na pectinase, nke na-enweghị ike imebi polymers kpọmkwem na enweghị ike nweta mmetụta na-emebi gel dị mma.

Tụkwasị na nke ahụ, ọ bụ ezie na onye na-agbaji gel na-emekarị enzyme bụ ihe na-agbaji mmiri gel na-agbaji ka mma na obere okpomọkụ, ọ na-achọ uru pH dị ala.N'ozuzu, ọrụ nke enzymes kacha elu mgbe pH = 6, na elu okpomọkụ na elu pH uru ga-eme ka enzyme kwụsị ọrụ.

4. kpọmkwem enzyme gel breaker

N'ihi nke a, a na-amụkwu usoro bioenzyme degelatinization ọhụrụ nke ọma na ngwa ngwa ya na oke pH, na-enyocha kpọmkwem hydrolases (LSE) maka njikọ glycoside nke polysaccharide polymers.Ha na-emebi naanị njikọ glycoside kpọmkwem na nhazi nke polysaccharide polymers, ma nwee ike iweda polymers n'ime monosaccharides na-adịghị ebelata na disaccharides.Enzymes ndị a na-agbaji gel kpọmkwem gụnyere cellulose glycoside bond kpọmkwem enzyme, starch glucoside bond kpọmkwem enzyme, guanidine glucoside bond kpọmkwem enzyme na na.

The encapsulated gel breakers wetara anyị bụ ngwaahịa emepụtara ọhụrụ n'afọ ndị na-adịbeghị anya.A na-eji teknụzụ mkpuchi dị elu mee ihe na-emepụta ihe mkpuchi nchebe na gel na-agbaji nkịtị, na-agbaji ọsọ gel na-achịkwa.A na-ejikarị ya na mgbawa mmiri nke Wells mmanụ, karịsịa na mgbaji nke ọkara na nke miri emi Wells.A na-ewepụta ihe ndị dị irè nke onye na-agbaji gel kpuchiri ekpuchi site na nhụsianya nrụnye.Uru ndị dị na ya bụ: ọdịnaya dị elu na-arụ ọrụ nke ọma, hapụ ya kpamkpam, belata nkwụsị nke ihe ndị na-arụ ọrụ, obere nsị, agbaji gel nke ọma, nkwụsị dị mfe, obere ihe fọdụrụnụ.
