基于层次分析法的页岩气集输管道风险评价方法研究

为完善国内页岩气集输管道风险评价技术,提出一种页岩气集输管道风险评价方法。该方法基于页岩气集输管道的实际情况,进行风险因素辨识,建立风险评价指标体系;采用层次分析法计算指标的权重,进而求得管道失效可能性;最后参考相关标准,计算得到页岩气集输管道的风险值。采用该方法对某页岩气集输管道进行风险评价,得到风险等级为:低风险。

In order to perfect the risk assessment technology of shale gas gathering and transportation pipeline in China,a risk assessment method of shale gas gathering and transportation pipeline is put forward.Based on the actual situation of shale gas gathering and transportation pipeline,this method identifies the risk factors and establishes the risk evaluation index system;the analytic hierarchy process(AHP)is used to calculate the weight of the index,and then the failure possibility of the pipeline is obtained.Finally,referring to the relevant standards,the risk value of shale gas gathering pipeline is calculated.This method is used to evaluate the risk of a shale gas gathering and transportation pipeline,and the risk grade is as follows:low risk.
