1. Zvinoshandiswa pakugadzira ivhu rakagadzikana
Kudzikamisa ivhu kunosanganisira zvinhu zviviri: kudzivirira kuzvimba kwemaminerari evhu uye kudzivirira kufamba kwemaminerari evhu. Kudzivirira kuzvimba kwemaminerari evhu, masurfactants ecationic akadai seamine salt type, quaternary ammonium salt type, pyridinium salt type, uye imidazoline salt type anogona kushandiswa. Kudzivirira kufamba kwemaminerari evhu, masurfactants asina fluorine-containing nonionic-cationic anogona kushandiswa.
2. Mishonga inosimbisa acidity
Kuti uwedzere acidizing effect, zvinowanzodiwa kuwedzera zvimwe zvinhu zvakasiyana-siyana mumushonga weasidhi. Chero surfactant inoenderana nemushonga weasidhi uye inonyungudutswa nyore nyore nekugadzirwa kwayo inogona kushandiswa se acidizing retarder. Mienzaniso inosanganisira fatty amine hydrochloride, quaternary ammonium salts, uye pyridinium salts pakati pe cationic surfactants, pamwe ne sulfonated, carboxymethylated, phosphate-esterified, kana sulfate-esterified polyoxyethylene alkyl phenol ethers pakati pe amphoteric surfactants. Mamwe ma surfactants, akadai se dodecyl sulfonic acid ne alkylamine salts dzayo, anogona emulsify musanganiswa weasidhi mumafuta kuti agadzire emulsion yeasidhi-mu-oil, iyo, kana ikashandiswa se acidizing working fluid, inoitawo basa rekudzora.
Mamwe ma surfactants anogona kushanda se demulsifiers yemvura inoita acid. Ma surfactants ane chimiro chemapazi, akadai se polyoxyethylene-polyoxypropylene propylene glycol ether uye polyoxyethylene-polyoxypropylene pentaethylenehexamine, ese anogona kushanda se acidizing demulsifiers.
Mamwe ma surfactants anogona kushanda se spent acid cleanup additives. Ma surfactants anogona kushandiswa se cleanup additives anosanganisira amine salt types, quaternary ammonium salt types, pyridinium salt types, non-ionic types, amphoteric types, uye fluorinated surfactants.
Mamwe ma surfactants anogona kushanda seanodzivirira acidizing sludge, akadai se surfactants inonyungudika mumafuta senge alkyl phenols, fatty acids, alkyl benzene sulfonic acids, uye quaternary ammonium salts. Sezvo acid yavo isinganyungudike zvakanaka, non-ionic surfactants inogona kushandiswa kuaparadzira mu acid solution.
Kuti uwedzere acidizing effect, zvakakosha kuwedzera wettability reversal agent mu acid solution kuti idzore wettability yenzvimbo iri pedyo newellbore kubva pamafuta-nyorova kuenda pamvura-nyorova. Misanganiswa yakaita se polyoxyethylene-polyoxypropylene alkyl alcohol ether uye phosphate-esterified polyoxyethylene-polyoxypropylene alkyl alcohol ether inonyungudutswa nekuumbwa sedanho rekutanga re adsorption, nokudaro ichiwana wettability reversal effect.
Pamusoro pezvo, kune mamwe ma surfactants, akadai se fatty amine hydrochloride, quaternary ammonium salts, kana non-ionic-anionic surfactants, anoshandiswa sema furo kugadzirira furo acid working fluids, zvichizadzisa zvinangwa zvekudzora, kudzivirira ngura, uye deep acidizing. Neimwe nzira, ma furo akadaro anogona kugadzirwa se pre-pads dzekuisa acidizing, ayo anopinzwa mukugadzirwa kwe acid solution isati yaiswa. Jamin effect inogadzirwa nemabubbles ari mu furo inogona kutsausa acid solution, ichimanikidza acid kuti inyungudise zvikamu zvishoma uye kuvandudza acidizing effect.
