RFT测井资料解释处理方法与软件应用

:基于RFT测井原理和预测试压力曲线资料，根据地下流体的渗流理论，研究了RFT测井资料的解释处理方法，解决了计算机自动拾取和人机交互提取测量点时间压力数据的问题，讨论了压降法求取地层渗透率的适用范围及其公式。应用所研究的方法，开发了RFT测井资料解释处理软件。用积分压降法可以准确地判断地层的渗透性，用绘制出的压力剖面图能够确定流体性质和流体界面。通过生产中的实际应用验证了该方法。

Interpretation and processing software for RFT log data

Based on repeat formation tester (RFT) logging principles and pretest pressure curve data, we studied interpretation and processing methods for RFT log data according to the seeping theory of underground fluid, and solved picking time-pressure values of measured points automatically and interactively. The range of application and formula for computing formation permeability by drawdown method were discussed. Accordingly, software for RFT log data interpretation and processing was developed. Formation permeability is exactly decided by integral drawdown method, and pressure evaluation profile is used to define fluid properties and its interface. The proposed method was verified in practice.
