Research On Optimization Of Coalbed Methane Gathering And Transportation Network

In Chinese “The 13 th Five-year Plan”,the development of natural gas pipeline has a new target.Along with the research results of “The 12 th Five-year Plan”is applied to “The 13 th Five-year Plan”,there will be more challenges for gas pipelines.The development of gas pipeline is becoming more and more complex.As an important part of the development of natural gas planning,in view of the problems faced by coal bed gas,people need to put forward corresponding solutions.At present,the development and research technology of gas gathering network is becoming mature,and many corresponding solutions to the complexity of gas well are put forward.Accordingly,the operation of coalbed methane in gas production,gas gathering and distribution is more and more complex,and the parameter variables involved in the process of operation are very many.This paper focuses on the gathering pipe network.At home and abroad,the research focuses on two aspects: the minimum energy consumption of the gathering and transportation network and the maximization of the final operation yield of the network system,In this paper,the first part is chosen as the research direction,and the pipe network model is simulated in Realpipe and Matlab simulation software.Realpipe is the simulation software of oil and gas pipeline network which has got good application in China at present.The following is the research content of this article:(1)According to the actual data collection of gathering and transporting network operation in Qinshui Basin,the optimization target is to select the minimum energy consumption by comparing the parameters related to the pressure and flow of the pipeline network.The objective function is selected by the contrast variable.(2)According to the existing mature natural gas pipeline transportation formula and constraint conditions,the corresponding mathematical model of coalbed methane is put forward,and its solution is carried out by geneticalgorithm and dynamic programming method respectively.(3)In the process of solution,the advantages and disadvantages of genetic algorithm and dynamic programming method applied to the operation system of coalbed methane gathering pipeline network are compared.The influence of the two algorithms on the optimization of coalbed methane is analyzed and the conclusion is drawn.(4)Through Realpipe pipe simulation software modeling,comparing the simulation results in Matlab,analyzing the data,comparing the dynamic programming method and genetic algorithm in the optimization effect of coal bed methane.
