摘　　要：从陕甘宁中部气田DST地层测试实测曲线形态出发，根据措施前压力恢复曲线的形态、措施前后产量以及钻井录井显示中有效裂缝段和有效孔洞段之和占气层总厚度的多少将压力恢复曲线与储层特征联系起来，将压力恢复曲线分为四类，其中Ⅱ类曲线形态所对应的储层最好，Ⅰ类稍次，Ⅲ类再次，Ⅳ类最差。为快速方便地决定对储层进行酸化改造与否提供了一种直观的方法。According to the shapes of the pressure the production rate and the ratio of the effect thickness to the total thickness before and after the well treatrnent, we found the relationship between the type of the buildup curves and the characteristics- Among the 4 kinds of the buildup curves,the second type gives the best characters of the reservoir,the first is better,the third is good and the forth girvoir. So that we developed a new quick method to divided weather or not the reservoir need acid treatment.
