| Abstract: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 transmission 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. |
