【Abstract】 Based on the studies of the fundamental data,the paper analyzes the intrinsic rule of the velocity variety of the upper Guantao Group sandstone which is of meandering river face and the velocity variety of its surrounding rock,concludes the view point that the velocity of the surrounding rock is lower than it of the sandstone,makes clear the seismic reflecting characteristics of the sandstone reservoir,probes into and summarizes the new techniques of reservoir predicting,reservoir depicting and hydrocarbon detecting.The techniques achieved a satisfying benefit in its applying in regions of the north Kendong area and the adjacent area of Gudong.更多还原
