Embodiment 1
[0022]Example 1; raw materials were weighed according to the following components and weight: aminoacetamide 20Kg, 3-amino-1,2,4-triazole 37Kg, crown ether (18-crown-6) 14Kg, dihydroxy sodium tartrate 14Kg , Ethosuximide 8Kg, N-hydroxyethylimine diacetic acid 9Kg, ethyl undecylenate 1Kg, 2-hydroxypropyl ethyl ether 15Kg, ammonia water (40wt%) 35Kg and water 75Kg.
[0023] Preparation method: add the liquid material components ethyl undecylenate and 2-hydroxypropyl ethyl ether into water first, stir well to obtain A liquid, then add the solid material components aminoacetamide, 3-amino-1 , 2,4-triazole, crown ether (18-crown-6), sodium dihydroxytartrate, ethosuximide, N-hydroxyethylimine diacetic acid, stir until the solid material components are fully dissolved to obtain liquid B, and then Ammonia water as a pH regulator is added to liquid B, and the pH of liquid B is adjusted to 10.8 with ammonia water to prepare an oilfield barium strontium scale cleaning and plugging remova...
Embodiment 2
[0024] Example 2: Weigh the raw materials according to the following components and weight: aminoacetamide 25Kg, 3-amino-1,2,4-triazole 33Kg, crown ether (18-crown-6) 10Kg, dihydroxy sodium tartrate 15Kg , Ethosuximide 7Kg, N-hydroxyethylimine diacetic acid 11Kg, ethyl undecylenate 3Kg, 2-hydroxypropyl ethyl ether 11Kg, ammonia water (40wt%) 30Kg and water 70Kg.
[0025] Preparation method: adjust the pH of liquid B to 10.2 with ammonia water, and the remainder is the same as in Example 1.
Embodiment 3
[0026] Example 3: raw materials were weighed according to the following components and weights: aminoacetamide 22Kg, 3-amino-1,2,4-triazole 34Kg, crown ether (18-crown-6) 11Kg, dihydroxy sodium tartrate 13Kg , Ethosuximide 9Kg, N-hydroxyethylimine diacetic acid 10Kg, ethyl undecylenate 2Kg, 2-hydroxypropyl ethyl ether 13Kg, ammonia water (40wt%) 31Kg and water 80Kg.
[0027] Preparation method: adjust the pH of liquid B to 10 with ammonia water, and the remainder is the same as in Example 1.
