Abstract: The viscosity reduction additive is introduced into the reaction system based on the traditional solution polymerization method and the gel type products oil drag reducing agent, PIPEWAY-S, is developed. Through optimized screening tests, the DRA samples are prepared in laboratory, which shows remarkable drag reduction and application capabilities and other eminent integrated performances. The industrial test of middle-scale DRA products are carried out in the Fushun-Bayuquan Products Oil Pipeline. The test results indicate that under the DRA dosage of 50 mg/kg, the pipeline throughput can be lifted from design capacity of 240×10⁴ t/a to 320×10⁴ t/a, 33% increase is achieved.
