摘　　要：苏里格气田是典型的低渗透气田,要准确计算其采收率和可采储量,必需确定气井的废弃条件。从对苏里格气田认识程度出发,采用经验公式法、气藏埋深法,以及经济—产能方程—井底流压法,计算苏里格气田苏20井区废弃地层压力,旨在为气田开发方案设计提供依据。Sulige gas field is a typical low-permeability gas field.Abandonment pressure must be determined to calculate its recovery factor and recoverable reserves accurately.Basis on the reservoir features of Sulige gas field,this paper adopts empirical formula,buried depth method and theoretical economic-deliverability equation-bottomhole flowing pressure method to calculate abandonment pressure of the area of Well Su20 of Sulige gas field which is used for laying a foundation of development plan of the gas field.
