摘要： 气井系统试井指示曲线常呈现异常,为了利用这些异常资料评价多层气藏的生产能力及流入动态、合理地划分开发层系,建立了二项式-单点法联解的方法,以处理这些异常试井资料,并得到气井各层的唯一的试井指示曲线和唯一的流入动态曲线;在此基础上,进一步分析多层气藏气井的生产能力、层间干扰,以及适宜的分采与合采方式。用该方法对矿场实例进行计算,结果表明,该方法可定量地评价多层气藏的层间于扰,确定合理的开采方式。

Abstract: A method for simultaneous-solution of one-point binomial is established for using the abnormal data or curves from systematic well test of gas well to evaluate the productivity and inflow performance of multilayer gas pool and reasonably clasify the layer series of development. The uniquely indicative curve and unique curve of inflow performance curve from each layer in gas well are based on the processing of these abnormal well test data. Also, the productivity, interlayer interference and corresponding processes of selective zone production and full zone production are analyzed and applied to the case study. The results show that this method can be used for quantitatively evaluating the interference of mulilayer gas pool, thus determining the rational production or recovery process.

Key words: gas reservoir, systematic well testing, anomaly, interlayer interference, recovery process
