Design and comparison of pressurization schemes for Linfen tight gas gathering and transportation network
In response to problems affecting the production increase target such as the diversification of production and pressure of tight gas wells in Linfen,the pressure of some wellheads lower than that of the gathering and transportation network,and the limited capacity of gathering and transmission network,a characteristics analysis of tight gas gathering and transportation network,along with the design and optimization of pressurization schemes,is carried out to improve the gathering and transportation capacity of the pipeline network.With PNS pipeline network simulation software,a systematic simulation model of the gathering and transportation network is established covering wellheads,well sites,gas gathering stations,and pipelines.After model calibration,the network characteristics are analyzed to determine the network gathering and transportation bottleneck and the pressurization position.Simulating calculations are conducted in terms of different pressurization modes,parameters,and schemes.Finally,concerning technological adaptability,economy,and equipment selection,the optimal pressurization scheme of Linfen tight gas gathering and transportation network comes into being,which means pressurizing the pipeline nodes in the Daji Ping18 branch line of Yongning 1 south trunk line and the Daji 1-9 branch line of Yongning 2 north trunk line respectively.The scheme suits best for the production status of tight gas in Linfen with the best pressurization effect.
