长输油气管道环境敏感区风险评估指标体系构建

Construction of Risk Assessment Index System for Environmental Sensitive Area of Long-distance Oil and Gas Pipelines

在肯特法指标体系的基础上,充分结合长输油气管道企业的实际情况,修正肯特法各评分项,调整各项的分值与权重,整合管道风险及敏感区属性,构建了长输油气管道环境敏感区风险评估指标体系,建立了符合长输油气管道特点的风险评估方法,从安全距离、人口数量、地下水敏感程度、土壤类型4个方面综合分析评估。利用该指标体系对企业所属敏感区进行分级、分类,依据管段得分划分出相应的风险等级,并以输油管道穿越人口密集区为例详细进行打分说明。该指标体系构建有助于企业对敏感区实施有效管理和重点监控,减少管道环境违规事件发生。

Based on the index system of Kent method,combined with the actual situation of pipeline enterprises,this paper revises the scoring items of Kent method and adjusts the scores and weights of each item,integrates the attributes of the pipeline risk and sensitive area.The risk assessment index system of sensitive area for long oil and gas pipeline was obtained.The risk assessment index system for sensitive areas has established a risk assessment method that meets the characteristics of long-distance oil and gas pipelines,analyzes and evaluates the safety distance,population,groundwater sensitivity,and soil type comprehensively.Divide the corresponding risk levels according to the pipe section scores,and give a detailed scoring explanation using the example of an oil pipeline crossing a densely populated area.The construction of this indicator system will help companies implement effective management and key monitoring of sensitive areas,reducing the occurrence of pipeline environmental violations.
