为降低煤层气地面勘探开发风险,节约成本,应用煤层气资源评价方法中的单因素指标法、模糊综合评价法、阶梯优选法、BP神经网络法等,结合C#开发语言,建立了煤层气资源评价系统;对煤层井开发影响因素分析基础上,应用模糊综合评价嵌套Comet产能模拟软件,建立了井型选择井网优化系统;根据GIS原理,建立了开发决策图形显示系统;煤层气开发决策系统采用了公共接口模块的外联式结构进行集成,将专家系统技术与地理信息技术结合并引入传统的地质学科是一个有益探索,该系统能较准确地为煤层气地面开发提供决策。

In order to reduce the development risk and cost of the coal bed methane exploration on the surface ground, the single factor index method, the fuzzy co mprehensive evaluation method, the step optimization method, the BP neural network method and others in the coal bed methane resource evaluation method were app lied to establish the coal bed methane resource evaluation system in combination with the C# development language.Based on the analysis on the factors affected to th e development of the coal bed methane well, the Fuzzy comprehensive evaluation system combined with the Comet production simulation software was applied to set U p an optimized system of the coal bed methane well network.According to the GIS principle, a graphic display system of the development decision-making was establish ed.The coal bed methane development decision-making system was integrated with an external structure of the public interface module and could combine the technical and geographic information of the expert system. The development decision-making system would be a profitable discovery to introduce the traditional geosciences an d could be accurate to provide the decision-making for the coal bed methane surface development.
