Abstract:

A foaming agent AGES for drilling wells has been synthesized for meeting needs of drilling technology with low pressure, low permeability oil and gas reservoir. It is synthesized by reacting dodecanol with epicholorodydin under catalyst TBE to produce choloro-dodecanol etherⅠ, which epoxidated in NaOH solution to form intermediate productⅡ, and then reacted with NaHSO3to obtain an anionic surfactant AGES. The properties of the product were tested by Waring Blender. Results show that AGES has excellent performance in aqueous solution with Ca2+5000 mg/L, salinity 5. 0×104mg/L, or in 20% kerosene . It didn’t decompose when used in 250℃for 6 hours.

Key words: drilling, foaming agent, surfactant
