摘要
分析了Saphir试井软件中段塞流压力资料解释方法原理:由段塞流压力数据得到定产量压降试井考虑井筒储存和表皮效应的等效压力导数,然后和Bourdet压力导数曲线进行拟合,从而求出地层参数,给出了具体的分析步骤。对某油田6口探井的段塞流压力资料进行了分析,并对解释结果进行了定量检验,从定量检验结果可以看出解释结果是比较正确的,从而表明应用Saphir试井软件的段塞流解释方法,可以对段塞流压力资料进行解释从而得到动态条件下的地层特性参数。
The principle of slug pressure data interpretation method in Saphir well testing software is analyzed. A equivalent pressure derivative of drawdown at constant rate is obtained that accounted for wellbore storage and skin. It is matched with Bourdet pressure derivative curve to obtain formation parameter. The concrete steps are given. Slug pressure data from six wells are analyzed. The result is checked quantitatively. The result shows that slug method is correct. Formation parameters can be obtained by applying slug method in Saphir software.
