Abstract: Gathering pipeline network adaptability evaluation, is to simulate the existing network when facing future possible working conditions, so as to assess its adaptability. Through numerical simulation, Canada Mackay River SAGD oil sand emulsion gathering pipeline network’s transient state is established, and Separated transportation and Multiphase transportation modes’ hydraulicthermal characteristic are analyzed, such as temperature dropping and pressure dropping. The result shows that the network based on the above two modes could satisfy the oil extraction and treatment requirement. For network corrosion issue, corrosion model is established to do the analog calculation. The result shows that in the separated transportation mode the carbon dioxide corrosion is severe, so multiphase transportation is recommended. Furthermore, the sand erosion prediction on pipeline elbow is calculated, the result shows that the erosion is not serious, network adaptability is good. The multiphase transportation and erosion analog calculation provides a accurate way of Canada SAGD oil sand gathering network adaptability evaluation, and it could be used for the network programming/updating/optimizing.
