数字化声波时差测井曲线逐点判别插值处理法

THE METHOD OF SUCCESSIVE DISCRMINATION AND INTERPOLATION OF DISTORTION POINTS OF DIGITAL SONIC INTERVAL TRANSIT$TIME LOG CURVE

用逐点判别插值法对数字化声波时差测井曲线进行处理，以５个测点或９个测点为一组合，逐点判别，剔除非正常点，再根据界面最大时差变化率和曲线形态及非正常点的分布类型对当前非正常时差点进行插值。

ith five or nine points combination, a log curve of digital sonic integral transit time is handled by the method Of successive discrimination and interPOlation of distortion POints. According to the high-lower limites of sonic Speed of local area stratas, whether or not suddenly changes of the current and nearby POints are distinguished in the combination, and the unnormal points of interval transit time are deleted. After rejecting the distortion POint, the current distortion interval transit time POint is interpolated by the varying rate of maximal interval transit time of interface and the curve form and the distribution type of unnormal POint.
