气井动储量落实及评价

Implementation and evaluation of gas well movable reserves

动态地质储量是指气藏中能够渗流或是流动的那部分天然气地质储量,它既是滚动开发、方案调整、宏观决策及相关科研工作的可靠物质基础和依据;也是探明地质储量可靠程度、动用程度的重要标志之一,气田开发的不同阶段,不断落实动态地质储量对气田的开发具有重要的指导意义。针对近年在气田应用过的动储量计算方法,对其理论原理、应用结果、适用范围等进行对比,优选出适用于榆林南区、子洲-米脂、苏里格东区的动储量计算方法。

Movable reserves is the foundation of performance analysis and dynamic index p rediction of gas well or gas reservoir. Material balance, production decline analysis and non - stabilized well test analysis are the proven methods calculating dynamic reserves of gas reservoirs. Taking Zizhou-and-Mizhi gas filed as an example, application condi2 tions and characteristics of different calculating methods are discussed. Movable reserves in Zizhou- and-Mizhi gas field can be determined by analyzing the calculations.
