摘　　要：确定煤层气开发目标时,选择经济性高的煤层气藏开发尤为重要。为了克服目前常规经济评价方法存在的计算过程繁琐、所需参数较多的缺点,结合目前高煤阶和中高煤阶煤层气藏的开发现状,充分考虑气价和内部收益率等对不同煤阶煤层气藏开发效益的影响,通过建立不同煤阶煤层气藏开发目标的“投资-产量-效益”评价图版实现快速评价优选,可为煤层气产能建设后备阵地的评价优选、煤层气目标优选、区块进退和投资控制或合理配产等提供科学、直观的决策依据。同时,作为一种新的评价手段,该方法也有助于提高工作效率,可推广到其他非常规资源。When determining the target,it is important to select th economic areas for coalbed methane development.In order to overcome the shortcomings of the cumbersome calculation process and the requirement of more parameters in the current conventional project evaluation methods,this paper combines the current development status of coalbed methane in high and medium-high coal rank reservoirs,and fully considers the impact of gas price and internal rate of return on the development benefits of coalbed methane in different coal rank reservoirs.By establishing the“investment-production benefit”evaluation chart for coalbed methane development objectives in different coal rank reservoirs which can realize rapid evaluation and optimization,it can provide a scientific and intuitive decision-making basis for the evaluation and optimization of reserve positions for coalbed methane production capacity construction,coalbed methane target optimization,block advance and retreat,investment control or reasonable production allocation,etc.At the same time,as a new evaluation method,this method also helps to improve efficiency and can be extended to other unconventional resources.
