Abstract:unit consisting of several laminae.Every one of the four wells, except well Lican- 1, has no industrial gas flow.The distributions of the three sand units were analysed using both drilling data and seismic data. According to the principle that the amplitude of reflection from gas-bearing formation increases with the increase of offset, seismic forward modeling was made, and the seismic data were analysed which had been processed using special methods.It was proved that the gas-bearing sand beds in this area not only have the property which is described in AVO technique but also show interval velocity anomaly and dim spot anomaly.The distributions of the gas-bearing sand beds have been ascertained using seismic data and drilling data.
