流动物质平衡法在复杂气藏中的适用性研究

摘要

It is vital to accurately judge cross well reservoir connectivity and verify gas dynamic reserves in order to guide gas wells production, initial output adjustment and optimize well pattern array of this special gas reservoir. Based on ideal model, flow material balance method uses gas production and well bore flow pressure to calculate dynamic reserves.This article established the model of complex gas reservoir and demonstrated flow material bal-ance method is suitable for reservoirs of irregular shape and multi well exploitation gas reservoirs.%准确计算气藏动态储量，对指导气井初期配产、产量调整和井网优化部署等都具有重要的意义。基于理想模型而建立的流动物质平衡方法不需要关井，只需使用日产气量和井底流动压力数据计算动态储量。本次研究通过建立复杂气藏模型，应用数值模拟技术论证了流动物质平衡法同样适用在边界形状不规则储层以及多井开采的气藏。
