| 摘 要： | 对于低渗透油田，在通常的关井压力恢复测试中，油井测压资料不能出现径向流直线段，针对这种情况建立了一种用早期续流段试井资料解释地层参数的实用方法，通过计算续流量利用褶积分析方法解释早期试井资料，可对实测压力数据点落在半对数直线段上方和下方的两种情况都收到较理想的解释效果，能解释出比较可靠的地层参数。这种新的解释方法大大提前了半对数直线段出现时间，缩短了关井时间．

| Abstract: | For low permeability oilfields, radial flow straight-line portion should not appear in producer measuring data during shut-in build up tests. A practical method to interpret formation parameters based on well testing data at early fillup period has been established With the application of this kind of method, ideal interpretation results can be obtained when the measure pressure data lie above and under semilog straight-line portion, and the formation parameters can be interpreted more reliably. This kind of new method can advance the appearance time for semilog straight-line portion, and shorten shut-in time. |
