摘　　要：英买力凝析气田已进入开发中后期,随着压力逐步下降,已建高压集输系统不满足生产需求。根据产能预测情况结合已建地面系统,提出3种优化布局方案,对末端降压进站、前端分散增压、前端集中增压工艺流程进行详细论证,基于各节点压力计算、工况及能耗分析、投资和经济比选,得出“前端集输系统集中增压、高压油气混合管输至处理厂”的方案更为适用。该方案最大程度利用了已建设施,不改变处理厂工艺流程;选用中、低压压缩机组合式增压技术路线,既节约能耗,又可提高各区块压力衰减不同步时的适应性。As the Yingmaili condensate gas field has entered its middle-late development stage,the pressure decreases constantly,and the existing high-pressure gathering and transportation system can no longer adapt to the production needs.According to the productivity prediction results,this paper proposes three optimal layout schemes on the basis of the existing surface system.The process flow of terminal inlet depressurization,front scattered pressurization,and front centralized pressurization are explored in detail.Scheme comparison and selection are conducted on the basis of node pressure calculation,load case and energy consumption analysis,and investment and economic benefit analysis.The results show that the scheme of“centralized pressurization in the front gathering and transportation system and pipelining of high-pressure gas and oil mixture to the processing plant”works best.Specifically,it makes the most of the existing facilities and does not change the process flow of the processing plant.Moreover,adopting the technical route of combined pressurization with low and medium pressure compressors,this scheme not only saves energy but also improves the adaptability in the case of unsynchronized pressure attenuation in the various blocks.
