Abstract

The invention discloses a sodium alkylphenol polyoxyethylene ether acetate ternary-compounded descaling agent. The sodium alkylphenol polyoxyethylene ether acetate ternary-compounded descaling agent is prepared through mixing and compounding sodium alkylphenol polyoxyethylene ether acetate, DTPA (Diethylene Triamine Pentacetate Acid) and EDTA (Ethylene Diamine Tetraacetic Acid) disodium salt, wherein in percentage by mass, the sodium alkylphenol polyoxyethylene ether acetate accounts for 10-30% of the total amount, the DTPA accounts for 20-40% of the total amount, and the EDTA disodium salt accounts for the balance of the total amount. The sodium alkylphenol polyoxyethylene ether acetate ternary-compounded descaling agent has good descaling performance, the synthesis cost is low, and the synthesis steps are simple, so that the market value is good.

Description

technical field [0001] The invention relates to a ternary compound descaling agent of alkylphenol polyoxyethylene ether sodium acetate. Background technique [0002] The most widely used surfactant types in the petroleum industry are anionic surfactants and nonionic surfactants. Anionic surfactants tend to precipitate in formation water with high salinity and lose their surface activity, while nonionic surfactants are difficult to dissolve when the temperature exceeds their cloud point. The anionic / nonionic surfactant with both anionic and nonionic on one molecule can overcome the deficiency of a single anionic or nonionic surfactant, and is suitable for high salinity and high temperature reservoir conditions. Alkylphenol polyoxyethylene ether carboxylate is one of them. APEC embeds a certain amount of ethylene oxide (EO) between the hydrophobic group and the hydrophilic group (-COO-), which makes it have water solubility and hard water resistance that ordinary anionic sur...
