摘要:

天然气压缩机运行到全寿命周期的后期及超期服役的压缩机组在运行过程中均存在一定的安全隐患,天然气

Abstract:

When natural gas compressors run into their full life cycle stage or extended service,there exist some hidden safety
troubles in the operation process,so their safety life assessment is crucial to managers and users of the oil and gas field. For
the units safety life assessment problem,research is carried out to clarify the relationship about the units integrity assessment
and each component weight. The paper determines the natural gas compressor unit overall assessment index system based
on components safety assessment. AHP is used to determine the components weights factor of the units. Aiming at security
indicators and economic indicators of the weights,the high-level judgment matrixes are determined. The judgment eigenvectors
and the largest eigenvalue were calculated by using the Matlab software. We must test the single-level consistency and the total
level of the consistency. Several adjustments have done to meet the single-level consistency and the total level consistency.
Finally the components of the compressor weights factor were determined and the theoretical basis was provided for the key
components′ life assessment of compressor. So,it should be placed more emphasis on the higher weight components in the
management and maintenance later days.
