摘要：

试并压力资料能有效表述储层非均质性。导数曲线中期有规律地向下弯曲,表明储层的储能系数增大;反之,储能系数减小。导数曲线中期是台阶状向上或向下偏离水平线时,表明储层的流动系数减小或增大,赫诺曲线径向流直线段的斜率也会相应变大或减小。塔里木盆地几个实例很好地说明了这一点。

Abstract:

The data of well-test pressure could be used to describe reservoir heterogeneity. Whenderivative curves bend downward in middle stage, the storage coefficient of the reservoir increases; on the contrary, the storage coefficient decreases. When the derivative curves stepup or step down from horizon, the flow coeficient of the reservoir also decreases or increases,and the obliqueness of the straight part of radial flow on Horner on.rve would become biggeror smaller accordingly. Several examples in Tarim basin have proved this.
