摘要
目前在中国国内运行的储气库中,有相当数量是从废弃的天然气藏转化而来的。对于这样的储气库,一旦投入运行以后,其工作井的产气能力量值,决定了储库的运行效率。借鉴常规气藏的动态产能评价方法,经研究改进后,应用于储气库条件下的工作井产能评价,推导了简单实用的现场工作井产能监测评价方法,并且针对长南地区下古生界地层拟设计为储气库工作井的气井,推导了储库工作井的IPR曲线,实际验证了这些工作井投入运行后的产能监测及分析方法可行性。
At present,among gas storages operated in China,a considerable amount is from the waste gas reservoirs. For such gas storages,once operated,the magnitude of its gas production capacity determines the reservoir's operating efficiency. By reference of dynamic capacity evaluation method to conventional gas reservoirs,after the study and improvement,and using work well productivity evaluation under gas storage conditions,a simple and practical field work well productivity monitoring and evaluation method is derived,and for the next Changnan Paleozoic proposed design for the formation of gas storage working gas wells,reservoir IPR curves derived work well,the actual verification of the production of these wells put into operation after work to monitor and analyze the feasibility of the method.
