Fracturing Izithasiselo
Ama-thickeners e-Acid Fracturing
Isingeniso somkhiqizo
Uhlelo lunokushisa okuphezulu nokumelana nosawoti, kulungele ukusebenza okujwayelekile kokuqhekeka kwemithombo kawoyela negesi phakathi kuka-60 ℃ no-160 ℃, ikakhulukazi kunemiphumela emangalisayo emithonjeni engaphezu kuka-120 ℃. Lolu hlelo lungasetshenziswa namanzi abuyela emuva esizeni, futhi umphumela ngeke uthinteke. I-UZP-160A nayo ingasetshenziswa njengesinciphisi sokudonsa.
I-Hydraulic fracturing, eyaziwa nangokuthi i-fracking, iyindlela yokuvuselela kahle esetshenziselwa ukukhipha igesi yemvelo kanye nowoyela ekujuleni kwamadwala angaphansi komhlaba. Le nqubo ihlanganisa ukujova ingxube yoketshezi olunomfutho ophezulu emthonjeni womthombo ukuze kudaleke ukuphuka edwaleni, okuvumela ama-hydrocarbon ukuthi ageleze ngokukhululeka futhi akhishelwe phezulu. Uketshezi olusetshenziswa ku-hydraulic fracturing, olwaziwa ngokuthi uketshezi oluqhekekayo, ngokuvamile luhlanganisa amanzi, izisetshenziswa (ezifana nesihlabathi noma ubuhlalu be-ceramic), nezithasiselo zamakhemikhali ezihlukahlukene, okuhlanganisa ama-agent axhumanisayo afana nezinhlanganisela ezisekelwe ku-zirconium.
I-Zirconium-based crosslinking agents, noma i-zirconium crosslinkers, idlala indima ebalulekile enqubweni yokuqhekeka kwe-hydraulic ngokuthuthukisa ukusebenza koketshezi oluphukayo. Lezi zinhlanganisela zenzelwe ukwandisa i-viscosity nokuzinza kwe-fracturing fluid, ngaleyo ndlela ithuthukise ikhono layo lokuthwala ama-proppants ezingxenyeni ezidalwe futhi igcine ubuqotho benethiwekhi yokuphuka. Ama-crosslinkers e-Zirconium afinyelela lokhu ngenqubo eyaziwa ngokuthi i-crosslinking, lapho enza khona amanethiwekhi aqinile, anezinhlangothi ezintathu ngaphakathi koketshezi, aluqinise ngokuphumelelayo futhi athuthukise amandla ayo okuthwala i-propant.
Enye yezinzuzo ezibalulekile ze-zirconium-based crosslinking agents ukuzinza kwazo okungavamile kokushisa, okubenza bafaneleke kahle ukusetshenziswa ezindaweni ezisezingeni lokushisa eziphansi ezivame ukuhlangana nazo kumachibi kawoyela negesi. Amandla abo okugcina uzinzo kanye ne-viscosity ngaphansi kwamazinga okushisa aphakeme aqinisekisa ukusebenza kahle koketshezi oluqhekekayo ezimweni eziyinselele zemigodi engaphansi, okunomthelela ekugqugquzelweni okuphumelelayo komthombo kanye nokuvuselela kabusha kwe-hydrocarbon.
Ngaphezu kwalokho, ama-crosslinkers e-zirconium anikezela ngezinzuzo zemvelo uma kuqhathaniswa namanye ama-agent wendabuko asekelwe ensimbi. Iphrofayili yabo evumelana nemvelo, ehambisana nezici zabo zokusebenza okuphezulu, ibenza babe ukukhetha okuthandwayo kokusebenza kokuqhekeka kwe-hydraulic, okuhambisana nokugxila okwandayo kwemboni emikhubeni eqhubekayo nethembekile.
Kafushane, i-zirconium-based crosslinking agents ibalulekile empumelelweni yokusebenza kwe-hydraulic fracturing, efaka isandla ekukhishweni okuphumelelayo kwegesi yemvelo kanye nowoyela kusuka ekubunjweni okungaphansi komhlaba. Ikhono lazo lokuthuthukisa ukusebenza nokuzinza koketshezi oluqhekekayo, okuhambisana nokuqina kwazo okushisayo nokuhambisana nemvelo, kuzibeka njengezingxenye ezibalulekile endaweni yesimanje yokukhiqiza uwoyela negesi. Njengoba imboni iqhubeka nokuvela, i-zirconium crosslinkers kulindeleke ukuthi ibambe iqhaza elibalulekile ekuthuthukiseni izinqubo ze-hydraulic fracturing kanye nokusekela ukuthuthukiswa kwamandla okuqhubekayo.

Izinhlelo zokusebenza
I-1.I-dosage ye-UZP-160A ilinganiswa ngokuvumelana nokuhlushwa kwengxube, gxuma ku-agitator ye-300-400r / min, kuzothatha amaminithi angu-30 kusukela ekuncibilikeni kahle ukuze enze isisombululo esifanayo, futhi i-viscosity ye-fluid eyisisekelo ithola ukuzinza.
2.Isikhathi sokuxhumanisa singalungiswa, futhi uhla lokulungisa luyimizuzu engu-0 ~ 2.
I-3.Isikhathi sokuphulwa kwesistimu singalungiswa ngokuvumelana nesimo sangempela (umthamo omncane we-ejenti ephulayo ngu-0.05%).
Ukuphatha Okunconyiwe
Bonke abasebenzi abaphethe lokhu kusebenza kufanele bakuphathe njengekhemikhali yemboni, bagqoke izinto zokuzivikela futhi babheke izinyathelo zokuphepha njengoba kuchazwe ku-Material Safety Data Sheet.
