The seismic reflection characteristics were analysed for several morphological patterns common in lacustrine sand bodies by means of the seismic analogue technique and experimental work has been carried out for prospecting medium to small sand bodies in Wuhaozhuang-Zhuangxi area of Jiyang depression

using seismic stratigraphic method.In this article

more detailed diseription is given of the seismic analogue profiles

the waveform characteristics and reflection structure of the medium and small sized sand bodies obtain

ed from these sections

such as horizontal stacking

stacked offset

synthetic sonic logging

deconvolution and the like recorded in this area have been also discribed in detail.Meanwhile

in respect to exploration of non-anticlinal reservoirs

prognosis of distribution trend of sand bodies in middle and lower parts of member E

of present area has been made in combination with data on geology

drilling and seismic stratigraphy

etc.

and their oil and gas potential has also been evaluated.
