1. Izinto ezisetyenziswa kudongwe oluzinzileyo
Ukuqinisa udongwe kubandakanya iinkalo ezimbini: ukuthintela ukudumba kweeminerali zodongwe kunye nokuthintela ukufuduka kweenxalenye zeeminerali zodongwe. Ukuthintela ukudumba kodongwe, ii-surfactants ze-cationic ezifana nohlobo lwetyuwa ye-amine, uhlobo lwetyuwa ye-quaternary ammonium, uhlobo lwetyuwa ye-pyridinium, kunye nohlobo lwetyuwa ye-imidazoline zingasetyenziswa. Ukuthintela ukufuduka kweenxalenye zeeminerali zodongwe, ii-surfactants ezingezizo ze-ionic-cationic eziqulethe i-fluorine zingasetyenziswa.
2.Ii-surfactants zokulinganisa i-asidi
Ukuphucula isiphumo sokusila, ngokuqhelekileyo kuyimfuneko ukongeza izongezo ezahlukeneyo kwisisombululo se-asidi. Nasiphi na i-surfactant ehambelana nesisombululo se-asidi kwaye efunxwa lula kukwakheka ingasetyenziswa njenge-acidizing retarder. Imizekelo ibandakanya ii-fatty amine hydrochloride, ii-quaternary ammonium salts, kunye nee-pyridinium salts phakathi kwee-cationic surfactants, kunye nee-sulfonated, carboxymethylated, phosphate-esterified, okanye i-sulfate-esterified polyoxyethylene alkyl phenol ethers phakathi kwee-amphoteric surfactants. Ezinye ii-surfactants, ezifana ne-dodecyl sulfonic acid kunye nee-alkylamine salts zayo, zinokusila isisombululo se-asidi kwioyile ukuze zenze i-acid-in-oil emulsion, ethi, xa isetyenziswa njengolwelo olusebenzayo lwe-acidizing, ikwadlala indima yokulibazisa.
Ezinye ii-surfactants zingasebenza njengee-demulsifiers kwii-fluids ezenza i-asidi. Ii-surfactants ezinesakhiwo esinamasebe, ezifana ne-polyoxyethylene-polyoxypropylene propylene glycol ether kunye ne-polyoxyethylene-polyoxypropylene pentaethylenehexamine, zonke zinokusebenza njengee-demulsifier ezenza i-asidi.
Ezinye ii-surfactants zingasebenza njengezongezo zokucoca i-asidi esetyenzisiweyo. Ii-surfactants ezinokusetyenziswa njengezongezo zokucoca ziquka iintlobo zetyuwa ye-amine, iintlobo zetyuwa ye-quaternary ammonium, iintlobo zetyuwa ye-pyridinium, iintlobo ezingezizo ze-ionic, iintlobo ze-amphoteric, kunye nee-surfactants ezifakwe i-fluorinated.
Ezinye izinto ezibangela ukunyibilika kwe-asidi zingasebenza njengezithinteli ze-asidi, ezifana nezinto ezibangela ukunyibilika kwe-oyile ezifana ne-alkyl phenols, ii-fatty acids, ii-alkyl benzene sulfonic acids, kunye nee-quaternary ammonium salts. Ekubeni ukunyibilika kwazo kwe-asidi kuncinci, izinto ezibangela ukunyibilika kwe-asidi zingasetyenziselwa ukuzisasaza kwisisombululo se-asidi.
Ukuphucula isiphumo sokwenza i-asidi ibe namandla, kuyimfuneko ukongeza i-arhente yokuguqula ukumanzi kwisisombululo se-asidi ukuze kuguqulwe ukumanzi kwendawo ekufutshane ne-wellbore ukusuka kwi-oyile-emanzi ukuya kwi-water-wet. Imixube efana ne-polyoxyethylene-polyoxypropylene alkyl alcohol ether kunye ne-phosphate-esterified polyoxyethylene-polyoxypropylene alkyl alcohol ether zifunxwa yi-formation njengomaleko wokuqala wokufunxwa, ngaloo ndlela kufezekiswa isiphumo sokuguqula ukumanzi.
Ukongeza, kukho ezinye izinto ezibangela ukuba i-surfactants, ezifana ne-fatty amine hydrochloride, i-quaternary ammonium salts, okanye ii-surfactants ezingezizo i-ionic-anionic, ezisetyenziswa njengee-agents ezikhupha i-foam acid ukulungiselela ulwelo olusebenzayo lwe-foam acid, ukufezekisa iinjongo zokulibazisa, ukuthintela ukugqwala, kunye nokwenza i-acid ibe nzulu. Ngaphandle koko, ezo foam zingalungiswa njengee-pre-pads zokwenza i-acid ibe nkulu, ezifakwa kwisakhiwo ngaphambi kwesisombululo se-asidi. Isiphumo seJamin esiveliswa ngamaqamza kwi-foam sinokuguqula isisombululo se-asidi, sinyanzele i-asidi ukuba inyibilikise ikakhulu iileya eziphantsi kokungena kwamanzi kwaye iphucule isiphumo sokwenza i-acid ibe nkulu.
