摘要 气井合理产能确定是气田开发早期的一项重要工作,是科学开发气田的基础。其无阻流量是合理产能确定的重要依据。针对气田开发早期开发井、勘探获气井、开发部署井3种不同类型气井并存的现状,通过四川气田多年的开发实践,给出了不同的无阻流量计算方法。在此基础上,提出了合理产能的确定原则,系统地介绍了5种气井合理产能确定方法并对其进行了评价。我们建议,气井合理产能的确定要综合考虑各种计算结果和气藏的地质特征。 It is important work at the early development stage of gas fields and the base of scientifically developing gas fields to determine the reasonable productivity of gas wells.The open flow rate is an important basis to determine the reasonable productivity.Aiming at the situation of 3 different kinds of gas wells,i.e.,assessment wells,exploration wells and development wells exist simultaneously at the early stage of gas-field development,with production practice of Sichuan gas field for many years,the calculating method is provided for different open flow rates.Then,the principle is proposed to determine the reasonable productivity.And 5 methods are systematically introduced and evaluated to determine reasonable productivity of gas wells.It is suggested the different calculating results and the geologic features of the gas reservoir should be considered comprehensively to determine the reasonable productivity of gas wells.
