Izithasiselo ze-Acidizing

I-Corrosion Inhibitors (CI: 201/203/401) yakhelwe ukuvikela ukugqwala ezindaweni ezine-acidic. Afanele ama-asidi anhlobonhlobo futhi angasetshenziselwa imisebenzi yokugeza i-asidi yamapayipi.

I-Youzhu Chem inikeza uhla olugcwele lwezinto eziphambukisayo Ekuphathweni Kwe-Acidizing Kawoyela kanye nokukhiqizwa kwegesi. eklanyelwe ukusiza ukubeka kahle ukwelashwa kwe-asidi eduze komthombo ukuze isize ukwenza idizayini yokwelapha efanele kanye nokuhlela ukuze kuqinisekiswe ukuthi i-asidi ayifakwa kuphela esikhawulweni esifanele.

I-Corrosion Inhibitor iyisengezo se-Drilling Fluid esinezelwa kuZiketshezi Zokubhoboza ukuze kugwenywe noma Kususwe Ukugqwala okubangela ukugoba nokukhathala kwezingxenye zensimbi, okuholela ekuhlulekeni kokuqala noma kungazelelwe kwemikhiqizo yensimbi efana namakholomu okubhoboza, i-casing kanye namathuluzi akhethekile.

Ama-Corrosion inhibitors asetshenziswa emithonjeni kawoyela negesi kusukela ngawo-1930s. Kulezi zinsuku, ama-corrosion inhibitors aziwa kakhulu njengendlela evamile yokulawula ukugqwala, ikakhulukazi emithonjeni eyenziwe ngezingxenye zensimbi ye-carbon.

Ama-Corrosion inhibitors asetshenziswa ekwelapheni i-asidi, isb. i-matrix acidizing, i-acid fracturing, noma ekwelapheni kokulawula isihlabathi. Uketshezi olune-acidic ephezulu luholela ekugqwaleni okukhulu kodwa i-Youzhu inikeza iphothifoliyo yama-corrosion inhibitors asetshenziswa njengezingxenye zokwakheka ezivikela izingxenye zensimbi emgodini womthombo noma kumashubhu ahlanganiswe emvelweni yokugqwala yoketshezi.

Izithasiselo ze-Corrosion Inhibitor zigwema ukugqwala emgodini wokukhiqiza kanye nesistimu yokuqoqa okubangelwa amanzi ahlobene nokukhiqizwa kukawoyela ongahluziwe ngaphambi kokuba ukugqwala kudle inzuzo ngenxa yezindleko ezikhulayo.

Ama-inhibitors ayindlela yokuqala yokuzivikela ngokumelene nokugqwala. Ezindaweni zikawoyela negesi kanye nezinhlelo zokukhiqiza, zinciphisa ubungozi bokugqwala okubangelwa yi-CO2, i-H2S, ama-asidi e-organic, nokunye okwengeziwe, ukubhekana nendawo, ngaphansi kwediphozithi, i-galvanic, nezinye izinhlobo zokugqwala ezingaholela ekuhlulekeni kwemishini.

I-ejenti ephambukisayo isetshenziselwa ukuxhuma okwesikhashana izendlalelo eziphezulu zokungena noma izindawo ezilashwayo ngesikhathi sokugalela i-asidi, okubangela ukuthi uketshezi lwe-asidi luphambukele ezendlaleloni zokungena okuphansi noma ezindaweni ezingaphathwanga ukuze kuzuzwe i-asidi efanayo.

Ngaphandle kwalokho, ubuchwepheshe be-hydraulic fracturing kanye ne-asidi fracturing buncike ejentini ephambukisayo ukuvimba ukuphuka amadala, ukuphuka kwemvelo noma ukuphuka okusha okusanda kuvulwa, okuphoqa uketshezi oluphukayo noma i-asidi ukuthi iphambukise ukuze kudaleke ukuphuka okusha okwengeziwe, ngaleyo ndlela kuzuzwe ukuphuka kwe-asidi yevolumu noma ukuphuka kwe-asidi yenethiwekhi.

Ama-Diverting agents, awaziwa nangokuthi abaphambukisi bamakhemikhali, basebenza ngokwakha umphumela wokuvinjwa wesikhashana, I-ejenti yamakhemikhali esetshenziswa ekwelapheni okushukumisayo ukuze kuqinisekiswe umjovo ofanayo endaweni okufanele ilashwe. Ekuthuthukiseni ukusebenza kahle kokuvuselela, i-Temporary Diverting Agent TDA-200 iyingxenye ebalulekile endaweni yokuvuselela kahle kanye nokusebenza kwe-hydraulic fracturing.

Ama-Diverting agents, awaziwa nangokuthi abaphambukisi bamakhemikhali, basebenza ngokwakha umphumela wokuvinjwa wesikhashana, I-ejenti yamakhemikhali esetshenziswa ekwelapheni okushukumisayo ukuze kuqinisekiswe umjovo ofanayo endaweni okufanele ilashwe. Ekuthuthukiseni ukusebenza kahle kokuvuselela, i-Temporary Diverting Agent TDA-200 iyingxenye ebalulekile endaweni yokuvuselela kahle kanye nokusebenza kwe-hydraulic fracturing.

Ukuthuthukisa ukutholakala kukawoyela ngokusebenzisa uketshezi oluthuthukisiwe lwe-viscosity njengesivimbeli sokuhamba. I-Acid thickener AT350P iyi-cationic, i-polymer enesisindo esiphezulu kakhulu ekhulisa i-viscosity ye-hydrochloric acid njenge-gelling acid.

Uketshezi lokwelapha olune-Viscosified lungasetshenziswa ezinhlobonhlobo zokwelapha ezingaphansi komhlaba. Ukwelashwa okunjalo kufaka, kodwa akukhawulelwe ekwelashweni kokuvuselela, ukulawulwa kwesihlabathi nezinye izinhlelo zokusebenza ezifanayo.

I-SFT-100 ye-surfactant isetshenziselwa ikakhulukazi uwoyela negesi kahle i-fracturing, i-acidizing kanye neminye imisebenzi engaphansi komhlaba, ukunciphisa ukungezwani kwendawo (noma ukungezwani kobuso), ukunciphisa ukwakheka kwe-porous medium capillary resistance, ukwenza ukwakhiwa kwe-residual fluid flowback ngokushesha nangaphezulu, ukuze unciphise ngempumelelo umonakalo wokwakheka.

Ama-surfactants asetshenziswa kakhulu enqubweni yokuqhekeka kwe-hydraulic ukuthuthukisa ukukhiqizwa kukawoyela/igesi nokunciphisa ukusetshenziswa kwamandla ngokulawula i-viscosity ephelele yoketshezi oluqhekekayo, ukunciphisa ukungezwani okungaphezulu/okuhlangene phakathi kokwakheka kwe-shale noketshezi oluphukayo, okusiza ukubuyiswa koketshezi ngemva kokuqhekeka, ukuguqula ukugeleza kwe-rock fractubility.

I-emulsifier i-amphiphilic molecule yesisindo esiphansi noma esiphezulu se-molecular evame ukufuduka futhi ikhangise ngokushesha ku-interface yamafutha (i-apolar) kanye namanzi (i-polar), ikhetha ukwakheka kwamaconsi asebenzisa amandla aphansi. Lezi zinhlanganisela zehlisa ukungezwani kobuso futhi zenze ifilimu kusixhumi esibonakalayo.

Ngephrojekthi yakho ye-matrix acidizing, i-Youzhu Chem ihlinzeka ngamakhemikhali e-acid emulsions.

Cishe u-60% kawoyela kanye nama-40% wezinqolobane zegesi emhlabeni wonke aqukethwe ezindaweni zokugcina i-carbonate lapho ukugqugquzela ukwenza i-asidi kuyinselele enkulu uma kuqhathaniswa namachibi e-sandstone.

Ukusetshenziswa kwe-emulsified acids ekusebenzeni kwe-matrix acidizing kube yindlela ephumelela kakhulu. Ngenkathi isebenza, i-Deep, imigudu emincane ikhiqiza, kanye nokusebenza kahle kakhulu kokushanela kanye nokuvimbela ukugqwala kwemishini yomthombo.

Kwa-Youzhu Chem Innovations on Corrosion inhibition izithasiselo zisetshenzisiwe ukuze kuthuthukiswe ukusebenza kwama-emulsified acid ezimweni ezahlukahlukene, imikhawulo yawo, kanye nezixazululo zentuthuko.
