Based on the molecular structure of corrosion inhibitor of brine,a product with a good performance has been synthesized by selecting reaction temperature,reaction time and ratio of raw material and its optimal dose has been selected.This paper gives a detailed description of weightlessness method used for researching the properties of how the corrosion inhibitor behaves to steel product in brine.The results show that it has a good salt resistant performance and an excellent resolution dispersion and can be compatible with selected other drilling fluids additives.Its effect is much better than other same kinds of products in this field.
