摘　　要：气藏动态储量的预测是制定开发方案、研究剩余储量挖潜的重要依据。针对孤家子气藏非均质性较强、渗透率较低、老区地层压力资料缺失等问题,运用流动物质平衡法以及基于井口套压换算推导井底压力的方法,结合孤家子气藏生产动态及渗流特征,将生产指标曲线分为4种类型,并对每种类型曲线的特征及形成原因进行描述,从而达到预测合理动态储量的目的。对区块动用面积进行圈定,后期通过地质建模及数值模拟对计算结果进行验证。计算结果表明,新的方法具有一定实用性,对以孤家子气藏为代表的老区的有效开发具有一定的指导意义。Prediction of dynamic reserves of gas reservoir is an important basis for formulating the development plan of tapping the potential of remaining reserves. In view of the problems such as strong heterogeneity, low permeability, and lack of formation pressure data in the old area of Gujiazi gas reservoir, the production index curves were divided into four types by using the flowing material balance method and the method of deriving bottom hole pressure based on wellhead casing pressure conversion,combined with the production performance and seepage characteristics of Gujiazi gas reservoir, and the characteristics and formation reasons of each type of curve were described, so as to achieve the purpose of predicting reasonable dynamic reserves.The produced area of the block was delineated, and the calculation results were verified by geological modeling and numerical simulation in the later stage. The calculation results show that the new method is practical and has certain guiding significance for the effective development of the old area represented by Gujiazi gas reservoir.
