煤层气选区评价指标权重研究

Study on Weight of CBM Selected Area Evaluation Index

通过分析各种指标权重确定方法的优劣点,考虑净现值、投资回报率等选区评价最终目的,厘清储层因素、盖层因素、支持环境因素等评价指标与投资成本的传导机制,借助敏感性分析、相关性分析和层次分析法进行定量或半定量研究,进而通过指标对经济效益的影响程度确定指标权重。研究成果可用于指导煤层气开发选区。

By analyzing the advantages and disadvantages of various index weighting methods,considering the net present value ,return on investment and other evaluation purposes ,clarifying the mechanism of evaluation index such as reservoir factor, cap rock factor, supporting environment factor transmits to the investment cost ,with sensitivity analysis ,correlation analysis and analytic hierarchy process to conduct quantitative or semi-quantitative research, through the evaluation of the impact of indicators on economic benefits,determines the weight of each evaluation index. Research results can be used in CBM development area selection.
