摘　　要：为针对性研究重庆地区煤层气地面抽采项目经济可行性,定性分析了煤层气典型开发特征对项目投入产出的影响,建立了考虑技术进步的煤层气开发项目经济评价模型,利用经济评价软件测算了重庆地区煤层气地面抽采井的潜在经济效益。研究结果表明当产量水平达到1500m^3/d,在重庆綦江地区开展煤层气地面抽采直井项目经济可行,且利用钻井学习曲线模型进行钻井周期估算可更加准确估算钻井投资。To specifically study the economic feasibility of CBM surface extraction project in Chongqing, the qualitative analysis of the impact of the typical characteristics of CBM development on project input and output is carried on, the CBM project economic evaluation model considering the influence of technology progress is established, and the potential economic benefits of CBM surface extraction well in Chongqing is measured by the economic evaluation software. The results shows that when the stable production is 1500m3/d, it has economic feasibility to carry on the CBM surface vertical well project in Qijiang area, and the CBM drilling investment can be estimated more accurately when using drilling study curve model estimating the drilling cycle.
