摘　　要：L气田是南海西部首个深水气田,具有开发模式复杂、数模模型分井区建立等特点。气田以水下井口方式对各井区进行联合开发,传统的研究方式难以考虑气藏、井筒与管网在共同约束条件下对开发生产的影响。本文根据气田研究实际需求,综合考虑气藏、井筒及管网各部分的相互作用关系,建立了包括地下气藏渗流、井筒举升流动及地面管网流动的一体化模型,通过一体化分析技术明确了单井合理配产范围,并进行气藏、井筒、管网、单井见水风险、平台水处理能力及外输压力等约束条件下的方案优化,解决了不同领域模拟间的数值模拟耦合问题,为气田开发方案、管网优化提供了可靠的参考依据。The L gasfield is the first deepwater gasfield in the west of the South China Sea,which has the characteristics of complex development model,digital model and the establishment of the well area.The gasfield is jointly developed in each well area in the form of underwater wellhead,it is difficult to consider the influence of gas reservoir,wellbore and pipe network on development and production with the traditional research.Based on the field study of the actual demand,for the first time considering the gas reservoir,wellbore and the pipe network interaction.This paper establishes the integrated model including gas seepage flow,wellbore lift and pipe flow,through the integrated analysis technique clearly reasonable range of single well production,and gas reservoir,wellbore,pipe network,water breakthrough risk of a single well,optimize water platform for water treatment capacity and output pressure of the constraints of the scheme.It solves the coupled numerical simulation of different field simulation problems between and provides reliable reference for the gasfield development scheme and pipe network optimization.
