Abstract
Conversion of a slow wave propagating in a fluid layer inside an elastic medium into a tube wave propagating in a borehole that intersects this layer is considered. It is shown that the total field of the latter wave consists of three summands of different physical nature. Seismograms of the slow and tube waves are presented. Bibliography: 5 titles.
