It can conduct borehole wall imaging with the imaging mode of high resolution in open hole. It can also conduct casing inspection and cement bonding evaluation with the full wave mode in the cased hole. The proposed tool was tested in open hole and cased hole. Results shows that this tool can evaluate the geologic feature information，such as fracture，hole and bedding structure in open hole. The casing thickness imaging，inner and outer diameter imaging and cement impedance imaging can also be measured in the cased hole. This tool can provide quantitative evaluation of casing corrosion and cement bonding quality.
