Performance and application:
● OAB-40 has mild performance, good foaming and foam stabilization, and can reduce the irritation of anionic surfactants; it has good compatibility with anionic, cationic, nonionic and amphoteric surfactants.
● OAB-40 has good antistatic properties, antibacterial properties, good biodegradability, and very low biological toxicity; strong resistance to salt and hard water.
● OAB-40 is used as a thickener, conditioning agent, wetting agent, antibacterial agent, antistatic agent, etc. in daily chemical or other industrial fields. It can also be used as the main agent, thickener, viscoelastic surfactant, oil displacing agent in oil and gas fields;
● The ultra-low interfacial tension between OAB-40 and crude oil can reach the order of 10-3mN·m-1. As a chemical oil displacement agent, it has a broad prospect. In salt solutions or acid solutions with different pH values, with the continuous concentration of hydrochloric acid With decreasing and increasing PH value, the viscosity of the system increases rapidly, forming viscoelastic solutions or gels with different strengths, which are used as the main agent for cleaning fracturing fluid, self-turning acid and viscoelastic surfactant (VES).
● OAB-40 is used in self-turning acid system, and it has the functions of mucidic acid, self-turning acid and slow acid. It is used in the shunt acidification of heterogeneous reservoirs. The acid system will automatically become viscous with the acid rock reaction, which has the effect of shunt acidification and will not cause secondary damage to the formation.
● OAB-40 is used in Viscoelastic Surfactant (VES) system, with easy preparation, easy construction, high viscosity, high elasticity, automatic steering, low friction, low acid loss, strong stability (salt resistance), easy There are no residues and no damage to the formation.
● OAB-40 has a temperature resistance of about 60°C, and is an ideal viscoelastic surfactant for heterogeneous reservoirs and low-permeability reservoirs in medium and low-temperature reservoirs-production stimulation and transformation operations.
● OAB-40 can be used in oil and gas field drilling, acidification, fracturing, oil displacement and other fields, and has achieved good results in many oil fields in China and abroad.
