废弃压力是计算气藏采收率和可采储量必不可少的参数之一。而废弃压力又受气藏原始压力、气藏埋深、储层非均质特征以及不同废弃条件等多因素的影响。本文以某气田为实例,利用4种传统的经验公式和稳定产能方程法分别计算该气田的废弃压力,旨在加深对该气田的了解,为开发方案设计提供依据。 Abandoned pressure is one of the parameters necessary to calculate the gas recovery and recoverable reserves. The pressure of abandonment is influenced by many factors, such as the original pressure of gas reservoir, the buried depth of gas reservoir, heterogeneity of reservoir and different waste conditions. Taking a gas field as an example, this paper calculates the abandonment pressure of the gas field by using four traditional empirical formulas and stable productivity equation respectively, so as to deepen the understanding of the gas field and provide a basis for the development of the scheme design.
