大直径超声测井仪数据处理技术的研究

The Research of Data Processing Technology of Ultrasonic Logger with Large Diameter

针对大直径钻井超声测井仪存在检测数据精确度不高的问题,提出了一套完整的数据处理方案,并通过大量的实验测试数据,建立了超声测距方程,提出了一种改进的曲线拟合算法。实验证明该算法对数据量较大的采样点进行曲线拟合具有明显效果。

Aiming at the problem of low precision of measuring data of ultrasonic logger with large diameter, an integrated data processing project was put forward in the paper. The equation of ultrasonic distance measurement was built up through a great deal of data from experiment and a new algorithm of curve fit was proposed. The results of experiment proved the algorithm has good effect for curve fit of huge amounts of data.
