Abstract

Abstract:

The working conditions of crude oil DRA is analyzed in this paper, the dragreducing mechanics and the impacting factors of DAR are given out, and the comprehensive property testing of DRA flowing through different size of pipes is introduced in simulated facility selfmade based on industrial standard, the conclusion is obtained that the drag reducing rate does not decline or increase as Reynolds number gets greater, the rate reaches maximum while Reynolds number is in a certain value, and under same condition of testing, the greater the agency concentration is, the more the number of high molecular dragreducing agency in unit fluid, the more the nonsheared dragreducing molecular after same shearing, and the dragreducing rate will increase after same times of shearing.

Key words: oil pipeline, DRA, drag reduction mechanics, Reynolds number
