【Abstract】 Using seismic method can reduce the number of detailed exploratory wells and appraisal wells, and save exploration investment. Clastic rocks of Shaximiao gas reservoir in Pingluoba gas field have the characteristics of low permeability and super compactedness. It can reduce the exploration risk and raise success ratio of drilling and exploration for using seismic description method to seek gas?bearing sandbody of high porosity and high permeability at the background of tight reservoirs. The features of the sandbody with different physical properties in study area are described using the Jason reservoir description software. The method of successful seismic description for favorable gas?bearing sandbody is summarized, and is applied with good results.更多还原
