| The paper focuses on post project evaluation of Seninglan gas pipeline double-track project,clarifies the research background and significance,introduces the development situation and trends of the post project evaluation,states the post project evaluation’s concept,principle,basic contents,basic steps and common methods;combines Guideline for Post Project Evaluation of Fixed Assets Investment of Central Enterprise issued by State-owned Assets Supervision and Administration Commission of the State Council and Post Project Evaluation compiling Detailed Rules of Oil and Gas Pipeline Construction issued by PetroChina Company Limited,sums up post project evaluation contents of oil and gas pipeline construction.Then it researches Seninglan gas pipeline double-track project approval,construction and state of operation,adopts comparative analysis approach to carry out the post project evaluation.Innovation of the paper lies in adopting weighted moving average method to predict gas transmission volume after the time-point of the post evaluation,in the premise that new resource has not been found in gas field,steady output can be kept in the operation period,which has practical significant.The author of the paper as one of principals participated in the whole process from the project approval to acceptance,collected a large number of first-hand data,these experiences and collected related information all lays a solid foundation for scientific and objective evaluation on the project.Some experiences of project construction are worth promoting,especially the management mode of"construction and management separation",construction management experience of the double-track pipeline,EPC general contracting mode.The research provides reference and evidence for future similar natural gas pipeline construction project preparation,planning and investment decision,and provides a reference for new investment project planning. |
