Improvement of optimizing model for coalbed methane pipeline in three-dimensional environment

Since investment for gas pipelines shares a big proportion in total investment during coalbed methane development, reducing the length of pipeline can significantly cut down the investment. In practices, the designers need to have rich experiences and knowledge with consideration to multiple ways for connecting two points of pipeline. To reduce the difficulties in practical design, many scholars have proposed the optimizing model for pipeline in three-dimensional environment. On the basis of current optimizing model for pipeline, this paper puts forward improvements of genetic algorithm in the background of coalbed methane field development. By means of case simulation, the verification results demonstrate that the improved algorithm can resolve the problem of optimizing model for coalbed methane pipeline in threedimensional environment more effectively.
