Research Status of Gas Gathering and Production Technology and Pipe Network Simu-lation in Sulige Gas Field
As the largest integrated gas field in inland China,the Sulige Gas Field has gradually re-duced formation pressure with the continuous extraction of natural gas.The innovation of gas produc-tion technology and the optimization of gas gathering pipeline layout have become the core issues for extending the production life of the gas field.The gas field effectively utilizes geothermal energy through downhole throttling technology to address hydrate blockage issues.The new type of lock core downhole throttling device has achieved a success rate of over 90%in single retrieval.The well layout scheme adopts a single well stringing connection technique,which shortens the length of gas production pipe-lines.Operational and management costs are reduced,resulting in a reduction of approximately 48.8%in construction investment.This article reviews the development trends of pipeline network model re-search in recent years,points out the advantages and disadvantages of different methods,and demon-strates the process of establishing a hydraulic calculation model for the skeleton pipeline network,and the algorithm flow of simulation software under the background of a 30%increase in gas production in Sulige Gas Field.TGNET software is used to simulate the pressure drop amplitude of the pipeline net-work,effectively suppressing hydrate generation and avoiding economic losses.A discussion is conduct-ed on the applicability evaluation of the gathering and transportation pipeline network,pointing out the impact of changes in production conditions on the operational efficiency of the pipeline network,and the necessity of establishing hydraulic calculation models for predicting and avoiding potential risks.
