摘要
过流式过环空找水仪持水率解释较为复杂,依靠实验室得到的刻度图版,人工解释效率低且易产生人为误差.提出基于刻度数据的三次样条函数处理解释方法,实现了测井解释的计算机自动处理.模拟实验与现场应用结果表明,在插值过程中对原始曲线和中间过程曲线进行2次平滑滤波,使计算结果更为准确,提高了工作效率,减少了人为误差,满足测井生产要求.
In-line annular water detector is a new kind of production logging tool which was developed by Daqing Logging and Testing Services Company in 1997.This paper gives a new processing method based on cubic spline interpolation to process the calibration data instead of artificial method,and this processing program can enhance work efficiency,and it can also raise the interpretation accuracy.This paper states the method of cubic spline interpolation and the method of water cut calibration,the analysis of field and laboratory experiment is also mentioned.
