Performance comparison of tubing in different injection wells

The residual stress of different water injection tubings was tested by blind hole method, and the corrosion performance of tubings was tested by electrochemical corrosion test and water contact angle method, and the performance of tubings with different materials was evaluated. The results show that the residual stress of coated tungsten alloy tubing, ordinary tubing, fiber glass reinforced plastic tubing and anti-scaling tubing decreased in turn. The corrosion resistance of fiber glass reinforced plastic tubing, coated tungsten alloy tubing, anti scaling tubing, and ordinary tubing was from high to low.
