摘要
通过对超声成像测井中因井壁声斑的非理想性所引造成图像退化因素的详细分析;并基于现场实验数据与实际测井资料的比对深入研究换能器的传输特性并寻求最佳点扩展函数;从而设计出退化图像的最佳复原算法,为进一步提高采样图像的清晰度与分辨率提供了有效方案。
Through the detailed analysis of the image degradation factors that be caused by non-ideal features of Borehole wall＇s Ultrasound speckle in the actual ultrasound imaging logging, Discuss the point that related to the transducer transmis- sion characteristics according to the comparison of the experimental data and the actual logging data deeply and look for the best point spread function, Then design the most suitable image restoration algorithm that face to the degraded image and give the solution that improve the clarity and resolution of sampling images.
