Abstract

Interpretation of cavern shapes measured by OBRGSChem Chemkop ultrasonic sensorA b s t r a c t: Frommore than 30 years OBRGSChem Chemkop has used a sonar device echosonda of its own design and construction for measuring shapes and volumes of cavities created in salt deposits. At the beginning the image of the cavity was created on electro- sensitive recording paper (analog recording) and its interpretation required the use of a special software. Since 1998 the digital recording of results has been introduced. This made it possible to create applications for automation of the interpretation process. During measurement images of cavities energetic field are obtained. Measurements are performed using aligned converter (energy is emitted horizontally) or tilted under the desired angle. In each case converter makes full circle rotation (360°). The obtained image of ultrasound field is filtered and shape of cavity is proposed. If automated algorithm fails, the shape can be changed by software user. The processes of filtration and interpretation of echograms created using aligned/tilted converter (was presented as well as the process of) and creation of final data file with a cavity image are discussed here.
