Design and Practices of Development Decision System for Coal Bed Methane

Abstract：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 comprehensive evaluation method,the step optimization method,the BP neural network method and others in the coal bed methane resource evaluation method were applied 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 the development of the coal bed methane well,the Fuzzy comprehensive evaluation system combined with the Comet production simulation software was applied to set up 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 established.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 and could be accurate to provide the decision-making for the coal bed methane surface development.
