Otu esi ahọpụta surfactants maka usoro nkwụsi ike ụrọ na acidization

1. Surfactants maka ụrọ kwụsiri ike

Iji mee ka ụrọ kwụsie ike gụnyere akụkụ abụọ: igbochi ọzịza nke mineral ụrọ na igbochi mbugharị nke mineral ụrọ. Iji gbochie ọzịza ụrọ, enwere ike iji cationic surfactants dị ka ụdị nnu amine, ụdị nnu ammonium quaternary, ụdị nnu pyridinium, na ụdị nnu imidazoline. Iji gbochie mbugharị nke mineral ụrọ, enwere ike iji surfactants nonionic-cationic nwere fluorine.

2. Surfactants maka nha acidization

Iji mee ka mmetụta acidization dịkwuo mma, ọ dị mkpa ịgbakwunye ihe mgbakwunye dị iche iche na ngwọta acid ahụ. Enwere ike iji surfactant ọ bụla nke dabara na ngwọta acid ahụ ma mee ka ọ dịrị mfe ịnweta ya dị ka ihe na-egbochi acidization. Ihe atụ gụnyere fatty amine hydrochloride, quaternary ammonium salts, na pyridinium salts n'etiti cationic surfactants, yana sulfonated, carboxymethylated, phosphate-esterified, ma ọ bụ sulfate-esterified polyoxyethylene alkyl phenol ethers n'etiti amphoteric surfactants. Ụfọdụ surfactants, dị ka dodecyl sulfonic acid na nnu alkylamine ya, nwere ike ime ka ngwọta acid dị na mmanụ mepụta emulsion acid-in-oil, nke, mgbe ejiri ya dị ka mmiri ọrụ acidizing, na-arụkwa ọrụ na-egbochi acidization.

Ụfọdụ surfactants nwere ike ịrụ ọrụ dị ka demulsifiers maka ime ka mmiri dị ọcha. Surfactants nwere usoro alaka, dị ka polyoxyethylene-polyoxypropylene propylene glycol ether na polyoxyethylene-polyoxypropylene pentaethylenehexamine, nwere ike ịrụ ọrụ dị ka demulsifiers na-eme ka acid dị ọcha.

Ụfọdụ surfactants nwere ike ịrụ ọrụ dị ka ihe mgbakwunye nhicha acid sped. Surfactants enwere ike iji dị ka ihe mgbakwunye nhicha gụnyere ụdị nnu amine, ụdị nnu ammonium quaternary, ụdị nnu pyridinium, ụdị ndị na-abụghị ionic, ụdị amphoteric, na surfactants fluorinated.

Ụfọdụ surfactants nwere ike ịrụ ọrụ dị ka ihe na-egbochi acidizing sludge, dị ka surfactants ndị na-agbaze mmanụ dịka alkyl phenols, fatty acids, alkyl benzene sulfonic acids, na quaternary ammonium salts. Ebe ọ bụ na acid ha anaghị agbaze nke ọma, enwere ike iji surfactants na-abụghị ionic gbasaa ha na mmiri acid.

Iji mee ka mmetụta acidity dịkwuo mma, ọ dị mkpa itinye ihe na-agbanwe mmiri mmiri na mmiri acid iji gbanwee ike mmiri mmiri nke mpaghara dị nso na olulu mmiri site na mmiri mmiri mmanụ gaa na mmiri mmiri mmiri. Ngwakọta dịka polyoxyethylene-polyoxypropylene alkyl alcohol ether na phosphate-esterified polyoxyethylene-polyoxypropylene alkyl alcohol ether na-abanye site na nhazi dị ka oyi akwa adsorption mbụ, si otú a na-enweta mmetụta mgbanwe mmiri mmiri.

Tinyere nke ahụ, e nwere ụfọdụ surfactants, dị ka fatty amine hydrochlorides, quaternary ammonium salts, ma ọ bụ non-ionic-anionic surfactants, nke a na-eji dị ka ihe na-eme ka ụfụfụ dị mfe iji kwadebe mmiri mmiri ụfụfụ na-arụ ọrụ, na-emezu ebumnuche nke igbochi nchara, igbochi nchara, na ime ka acid dị omimi. Ma ọ bụghị ya, enwere ike ịkwadebe ụfụfụ ndị dị otú ahụ dị ka ihe mgbochi maka ime ka acid dị mma, nke a na-agbanye n'ime nhazi tupu ngwọta acid ahụ. Mmetụta Jamin nke ụfụfụ dị na ụfụfụ ahụ na-emepụta nwere ike ịtụgharị mmiri acid ahụ, na-amanye acid ahụ ka ọ gbazee oyi akwa ndị na-adịghị agafe agafe ma melite mmetụta acidizing.
