摘　　要：为提高数值模拟中压力指标拟合精度，充分利用实测压力数据，需要将数值试井与数值模拟方法结合起来。为此，在精细地质建模的基础上，通过数值模型的直接转化，建立精细的数值试井地质模型，编制了实用软件，给出了2种方法有机结合的途径及具体步骤，并在实际区块进行了应用。方法使得单井及平面的试井解释结果更加准确丰富，数值模拟压力拟合速度及精度大大提高，对于水驱油藏进一步精细挖潜，提高剩余油描述精度和油藏监测水平具有重要意义。In order to enhance the match precision of the pressure indexes in numerical simulation and make full use of the measured pressure data, the combined method between numerical well test and numerical simulation is needed. Therefore on the basis of fine geological modeling and with the help of the direct conversion of the numeri- cal model, the fine geological model of numerical well test is established, the practical software is developed and furthermore two organically integrated methods and specific steps are presented. At the same time, the method is applied in actual blocks. Thanks to the above method, the results of the well test interpretation for both individual well and the total horizontal block are more accurate and complete, the match speed and precision for the numeri- cally simulated pressures are greatly increased, thus for those water flooded oil reservoirs, the new method possesses very important significance in further potential tapping and enhancing the precision of remained oil description and the level of the reservoir monitoring.
