摘要
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。
This paper analyzes the phenomenon that the average formation pressure of second time infill wells reckoned with presently using'Song I. 'method is particularly low, it indicates that calculation of average formation pressure with 'definite volume method'represented by'Song I 'does not adopt to reservoir development characteristics of second time infill wells. This paper studies and utilizes a calculation method for reckoning average formation pressure-pressure build-up'velocity method',which is suitable to reservoir development characteristics of second time infill well, and verifies file calculation results of the method through actual formation pressure data, at the same time the application conditions of the method are also given .The results show that the average pressure calculated with the method can accurately illustrate real pressure level of second time infill wells.
