Overview

Randomized trial investigates wax deposition control in high-paraffin crude oils, highlighting effective chemical additives.

Key Points

  • This research aims to analyze the rheological behavior and wax deposition in high-paraffin blended crude oils.
  • Examined low-temperature rheological properties of crude oil blends.
  • Utilized the Herschel-Bulkley model for behavior characterization.
  • Evaluated the impact of chemical additives on flow stability and wax deposition.
  • Temperature decrease significantly increased yield stress and effective viscosity, indicating a structured paraffin network.
  • Composite additive DHC displayed the highest efficiency, leading to improved flow characteristics and reduced wax deposition.
  • Strong correlations between pour point, yield stress, and consistency index confirm crystallization's role in flow resistance.
