摘　　要：在实际生产开发中,测井资料中声波和密度在识别气层,预测气层产能起着重要作用。本文以声波、密度测井资料为基础,分析其与气井生产能力相关性,找到了一种简便预测气井实际生产能力的新方法。利用该方法预测的10口气井的产能与实际产能对比,偏差在-3.38%~23.07%,结果表明该方法具有一定可行性。In the practical exploitation reality,density log and sonic log play an important role in gas reservoir recognition and productivity prediction.By using density log and sonic log information together and analysing the relativity,this paper find a new method that pre- dicts gas well productivity easily and this method is credible by predicting 10 gas wells pro- ductivity and making a comparison between the predict data and the actual data to test the results.The 10 sample＇s predicting result indicates that the error of predicting value range is from -3.38 %-23.0 % by using this method.The result indicates that this method may be feasible.
