对目前所用的“松Ⅰ”法推算二次加密井平均地层压力普遍偏低这一现象进行了分析 ,认为以“松Ⅰ”法为代表的“定积法”计算平均地层压力不适应二次加密井储层开采特点。研究应用了一种适合推算二次加密井储层开采特点的平均地层压力计算方法———压力恢复“速度法” ,并通过地层压力实测资料对该方法的计算结果进行了验证 ,同时也给出了该方法的应用条件。结果表明 ,用该方法计算的平均压力能较准确地反应二次加密井的真实压力水平。
The analysis of the phenomenon that the average formation pressure in the secondary infill wells is generally low when the “Song Ⅰ” method is used at present is analyzed. It is considered that the average formation pressure calculated by the “Song Ⅰ” method is not suitable for the secondary formation Crypto well reservoir mining characteristics. This paper studies a method of calculating the average formation pressure, which is suitable for estimating the characteristics of secondary wellbore mining, called the “velocity recovery method” and verifies the calculation results of the method by using measured data of formation pressure. The method of application of the conditions. The results show that the average pressure calculated by this method can reflect the true pressure of the secondary well more accurately.
