摘　　要：地面钻井是煤层气开发的主要方式之一,其开发周期、投资和成本费用等与常规天然气开发不同,并影响其经济效益。为了给煤层气开发利用及投资决策提供科学依据,以沁水盆地某煤层气开发区块为例,依据其目前的各项参数,利用现金流量法进行了经济评价和影响因素敏感性分析。结果表明,影响项目盈利能力的主要因素有产量、投资、成本、产品销售价格和补贴。从敏感性分析可以看出,财务内部收益率对投资、气价和产量较为敏感,其次是成本、补贴。因此,为了提高煤层气开发项目的经济效益,需要进一步提高煤层气价格,更需要通过开发理论的创新和开发技术的进步来增加单井产量、降低投资和成本。此外,建议国家根据不同地区、不同企业的生产实际情况,给予生产企业诸如加大补贴力度等更多优惠政策。Different from that of conventional natural gas resources,CBM gas development involves a high cost,a long construction circle,and a high investment risk.Taking a certain CBM gas development block in the Qinshui Basin as a case study,a model of economic evaluation on this CBM gas project is built by use of the Cash Flow Method and the sensitivity analysis of the influencing factors is also made.The calculation analysis shows that the main factors which are closely related to the profitability of this CBM project include the production capacity,investment,cost,selling price of product,and the policy subsidies.The sensitivity analysis demonstrates that the internal rate of return is more sensitive to the investment,gas price,and production capacity,then to the cost and subsidies.Therefore,in order to enhance the economic profit of this CBM development project,the CBM gas price needs to be further improved;more than that,the production per well is to be increased and the investment and cost to be cut down through the innovative theoretical studies and advanced development techniques.In addition,more preferential policies like increasing the policy subsidies should be formulated for the operators of such CBM development projects according to different production statuses in different areas.
