提出了采用层次分析-模糊综合评价法对含油钻屑锤磨式热解析处理系统进行经济性评价的方法。根据含油钻屑锤磨式热解析处理系统工艺流程分析和层次分析，选取5个一级指标、18个二级评价指标，建立了含油钻屑锤磨式热解析处理系统经济性评价指标体系。以层次分析法确定经济性评价指标权重和主要影响因素；用模糊综合评价法进行经济性评价，得到了含油钻屑锤磨式热解析处理系统经济性"适中"的结论，说明该系统具有主动生产和推广应用的价值。根据经济性指标权重和模糊综合评价分析，通过降低锤磨机、预混罐、保温加热装置能耗和锤磨机维修费用，可进一步提高含油钻屑锤磨式热解析处理系统的经济性。

Analytic hierarchy process (AHP)-fuzzy comprehensive evaluation method is proposed to evaluate the economic performance of the hammer-milling thermal desorption processing oily drilling cuttings system.According to the process flow analysis and the hierarchical analysis on the system,five first-level indexes and 18 second-level evaluation indexes are selected to establish the economic evaluation index system for the hammer-milling thermal desorption processing system.AHP is used to determine the weight of the economic evaluation index,and determine the most important factors affecting the economics of the hammer-milling thermal desorption processing oily drilling cuttings system.The fuzzy comprehensive evaluation method is used to carry out economic evaluation,gaining a conclusion that the economy of the hammer-milling thermal desorption processing oily drilling cuttings system is "moderate".It is shown that the hammer-milling thermal desorption processing oily drilling cuttings system has the values of active production and application promotion.According to the economic index weight and fuzzy comprehensive evaluation analysis,the economy of the hammer-milling thermal desorption processing oily drilling cuttings system can be further improved by reducing the energy consumption of hammer mill,premix tank and heat preservation heating device,and decreasing hammer mill maintenance cost.
