页岩气开发绿色承包商三级综合评价体系

Shale gas development green contractor three-level comprehensive evaluation system

"油公司"模式下,页岩气开发企业需要选择众多的承包商提供服务以实现自己的开发建设目标,要降低项目建设过程中承包商的非系统性风险,就需要加强对承包商的事前选择,提升其绿色施工能力。为了提升页岩气开发承包商的绿色水平,从源头上把控承包商质量,基于绿色承包商的概念,采用文献调研、专家访谈和量化打分等方法,构建了页岩气开发绿色承包商三级(1-7-20)综合评价体系;进而根据层次分析法确定各项指标的权重,提出关键影响指标;最后以某页岩气开发项目为案例,采用模糊层次分析法验证了该综合评价体系的实用性和有效性。研究结果表明:(1)绿色承包商概念是绿色页岩气开发落地的关键,三级综合评价体系涵盖的各项指标可以较好地反映绿色承包商事前管理的要求;(2)绿色施工技术与设备水平、安全健康环境管理体系成熟度、技术能力成长计划及投入,是选择绿色承包商的关键指标。结论认为,页岩气开发绿色承包商三级综合评价体系可以较好地满足承包商现场评价前瞻性、科学性和简便性的要求,能够为企业绿色承包商事前阶段综合评价提供参考。

In the mode of"oil company",shale gas development enterprises have to select numerous contractors to provide service,so as to realize the development construction goal.To reduce the non-systematical risks of contractors in the process of project construction,it is necessary to strengthen the pre-stage selection of contractors and improve their capability of green construction.In order to improve the green level of shale gas development contractors and control the quality of contractors from the very beginning,this paper constructs a three-level(1-7-20)comprehensive evaluation system of green contractor for shale gas development based on the concept of green contractor,by means of literature investigation,expert interview and quantitative scoring.Then,the weight of each index is determined by means of analytical hierarchy process,and the key influential indexes are pointed out.Finally,a certain shale gas development project is taken as an example to verify the practicability and effectiveness of the comprehensive evaluation system by using the fuzzy analytical hierarchy process.And the following research results are obtained.First,the concept of green contractor is the key to the implementation of green shale gas development,and the indexes involved in the three-level comprehensive evaluation system can better reflect the pre-management requirements of green contractors.Second,the green construction technology and equipment level,the safety,health and environmental management system maturity and the technical capability growth plan and investment are the key indicators to select green contractors.In conclusion,the three-level comprehensive evaluation system of green contractors for shale gas development can better meet the requirements of on-site contractor evaluation for foresight,science and simplicity and provide a reference for the pre-stage comprehensive evaluation of green contractors.
