The Study Of Natural Gas Field Development Engineering Environmental Supervision Evaluation Index System

By a natural gas development engineering environmental supervision practice, build gas field development engineering environmental supervision evaluation index system.Hoping to make project owner and related units to better understanding of engineering environment supervision effect, understand engineering environmental supervision on the importance of the natural gas field development, but also for the owner of the environmental management and decision-making, provides the basis.Natural gas field development is ecological impacting project,and its features are: complex pollutants, environmental impact time long, affects range, ecological disturbances.It emphasis on drilling wastewater and drilling waste mud treatment and disposal of cuttings, noise control measures and soil and water conservation measures to carry out the situation, environmental risk accident emergency measures of supervision and inspection.It analyzes the content and features of the gas field development engineering environmental supervision, on the study of domestic and foreign relevant theory and the relevant state regulations and standards,to assess natural gas field development environmental supervision for construction project goal, first effect from the pollution of ecological, environmental protection measures, environmental management, social class four aspects of total 22 indexes established the index system of the evaluation index system, including quantitative index 8, qualitative indexes 14. To ensure the integrity of the evaluation index system and effectiveness.Using AHP evaluation method to calculate the weight of each index, and through standard dimensionless method of qualitative and quantitative indexes all dimensionless processing, finally calculated the comprehensive evaluation value and the completion of the evaluation system. Finally by constructing evaluation index system in a domestic gas field development engineering evaluation results show that the effect of the environmental supervision conducted during the "good", and the effect of evaluation result is analyzed.
