【摘要】 综合研究了几种可以用于确定地层系数、表皮因子和原始地层压力的段塞流直线分析方法。如果段塞流测试时间不够长,大部分段塞流数据会受到井筒存储的影响,在这种情况下,既是用合适的考虑井储和表皮的典型曲线也难于获得实际数据的唯一拟合。通过分析冀东油田24 h段塞流测试资料,说明了这些段塞流直线分析方法,特别是反卷积导数方法,在缩短段塞流试井时间方面的应用效果。更多还原

【Abstract】 Several beeline analysis methods for determining formation flow capacity, skin factor and initial reservoir pressure from slug-test data are reviewed. If the slug test is not long enough, most of the slug-test data is dominated by wellbore-storage effects. In such cases, it is difficult to obtain a unique match of the real data with the appropriate wellbore-storage and skin type curves. By analyzing the 24h-elapsed-time slug test data from Jidong oilfield, the applicability of the beeline analysis methods, especially for "Peres modified Peres deconvolution" method, in reducing the slug test time are explained更多还原
