Discussion on Techno-Economic Evaluations of Materials Selection for OCTG

The plan of materials selection for OCTG needs to be made based on consideration of both the technical requirements and the economic benefits. Techno-economic evaluation methods are described, and a simple techno-economic index system is established, and the index powers are presented. With the value evaluation method, a techno-economic analysis of the materials selection for OCTG of a certain oil field is conducted. The result of the analysis shows that Plan 1 is much better Plan 2, so it is effective and practical to apply the techno- economic evaluation method to OCTG material selection.
