[Abstract]:With the development and application of natural gas resources, gas gathering and transportation network system is becoming larger and more complicated.In order to solve the problem of optimization design of gas field pipe network system economically, safely and reasonably, it is urgent to introduce optimization technology to optimize design, optimize management, optimize dispatching and optimize reconstruction and extension of complex gas field pipe network system.To promote the prosperity of the national economy.In this paper, a large number of investigations are carried out on the status quo and theoretical algorithms of pipeline network optimization. Following the latest research results in natural gas network system optimization technology at home and abroad, the pipeline layout optimization of gas field is studied in depth, and the pipe diameter is determined.Wall thickness and pipe parameters.According to the connection characteristic of gas field gathering and transportation tree pipe network and taking the shortest total output length of pipeline network as the goal, an improved mathematical model of gathering and transportation system optimization of multi-star tree pipe network is established.In this paper, a hybrid genetic algorithm combining genetic algorithm and Dijkstra algorithm is used to solve the problem, and the global optimal solution is obtained.In this paper, VB language is used to develop a visual "gas field pipe network layout optimization software", which can be applied to various gas fields. The technology of graphical user interface (GUI) and computer image technology (object connection and embedding) are used synthetically.Database technology and object oriented technology combine engineering design with computer programming to realize the optimization of gas field gathering and transportation network.By applying the self-compiled gas field layout optimization software to the A gas field, the total output length of the improved multi-star tree network gathering and transportation system and the unimproved pipeline gathering and transportation system is compared.It is found that the total output length of the improved gas gathering and transportation pipeline network can be reduced by 14.07, which further verifies the optimization effect of self-programming software in layout.On the basis of optimizing the distribution of gathering and transportation network in A gas field, the structural parameters of gathering and transportation network are compared and selected, and the parameters such as pipe diameter, wall thickness and pipe material specification that meet the requirements of technology are determined.Through the simulation software of pipe network, the results of parameter comparison and selection are simulated and calculated, and the running results are in accordance with the actual situation in the field, thus the results of the structural parameters of the pipe network in this paper are verified.
