Description

technical field [0001] The invention relates to a supramolecular polymer oil product drag reducing agent for pipeline oil product drag reduction and a preparation method thereof. It relates to the technical field of polymer compound compositions and piping systems. Background technique [0002] Pipeline transportation of oil products is the main mode of transportation of crude oil and refined oil products. About 90% of the crude oil and refined oil products in the world are transported by pipelines. Pipeline transportation drag reduction technology is one of the key factors restricting pipeline construction cost, pipeline operation cost, and even the safety of the entire pipeline. At present, technical solutions such as adding oil drag reducers are used at home and abroad to solve the above problems. Among the technical solutions for drag reduction in oil pipeline transportation, poly-α-olefin drag reducers based on macromolecular polymers dominate. This type of polymer ...
