试井实测数据的B样条磨光

由于外界因素的干扰 ,测试压力数据都会产生不同程度的振荡 ,影响试井分析结果的准确性 ,因此 ,在实际试井资料的处理过程中 ,需要对数据进行必要的磨光处理 ,以减少测试噪音的影响 ,达到准确分析的目的。采用B样条曲线对实测数据进行磨光 ,可以保证压力导数曲线具有很好的光滑性、光顺性和逼近度。实例证明 ,该方法简单易用 ,计算精度高

B- Spline Smoothing Method of Measured Data of Well Testing

The disturbance of external factor will make the measured pressure data fluctuate to different extent and affect the precision of the result of subsequent well test analyses.So,while processing the factual well test data,they should be smoothed to reduce the influence of testing noise.The exact analytical result can be achieved.The method,using B-spline curve to smooth measured data,can ensure the better velvet,smoothness and fidelity.The example illustrates that the B-spline smoothing method is effective and the result of calculation is reliable.
