为了准确对X气田各井生产动态进行预测分析,基于单井及气藏地质特征,建立气藏数值模拟,在历史拟合基础上,对各层剩余油气分布、可采储量和气水关系进行整体分析,最终明确了气藏各气井见水时间,并通过单井产气量预测确定了单井稳产时间,得出大部分气井在预测时间内能保持稳产的结论,这对X气田未来气井的开发和提高采收率提供了指导意义。
In order to accurately predict the production dynamics of each well in the X gas field, based on the geological characteristics of single well and gas reservoir, a numerical simulation of gas reservoir is established. On the basis of history fitting, the relationship between remaining oil and gas distribution, recoverable reserves and gas-water relationship Finally, the water breakthrough time of each gas well in the gas reservoir is finally determined, and the single well stable production time is determined by the single well gas production prediction. The conclusion is reached that most of the gas wells can maintain stable production within the forecast time, which is of great significance to the future development of gas wells in the X gas field And to improve oil recovery provides guidance.
