摘　　要：储量评价贯穿气藏开发始终,系统梳理气藏不同储量计算方法,对认识和开发气藏具有重要意义。前期评价阶段,分气藏类型选择容积法或体积法计算探明地质储量,指导开发概念设计和开发方案编制;方案实施阶段,落实可动用储量,指导井位部署;规模开发后,采用物质平衡与现代递减方法计算单井或气藏动态储量和可采储量,指导井网、井距、生产制度等开发技术政策优化;开发中后期,采用精细气藏描述和数值模拟方法落实剩余储量,指导挖潜部署。综合来看,储集空间结构、流体赋存状态和气藏边界是优选不同储量计算方法的重要依据,也是开发全生命周期不断认识气藏的关键参数。Reserve evaluation is very important in the full life cycle of gas reservoir.So it is of great significance to sort out different calculation methods of reserves systematically in the process of understanding and developing gas reservoirs.In the early evaluation stage,the proved reserves,which are the basis of conceptual design and development plan for gas field development,can be calculated by the volumetric method or reservoir?volume?method according to the reservoir type.During the implementation of the development plan,producing?reserves should be determined to guide well placement.With the large-scale development the dynamic reserves and recoverable reserves of wells or reservoirs are calculated by using the material balance and modern decline method to guide the optimization of technical policies such as well pattern,well spacing and production practices.In the middle and late stage of development,gas reservoir fine description and numerical simulation are used to determine the remaining reserves and guide the tapping potential.On the whole,the three factors,the spatial structure of the reservoir,the occurrence state of the fluid and the boundary of gas reservoir are important bases for optimizing the calculation method of different reserves,are also the key parameters for continuous understanding of gas reservoir in the whole development life cycle.
