In reservoir research, making full use of computer technology to extract a variety of parameters along the horizon to explore the horizontal variation of reservoirs has become a continuous development direction of reservoir research. Using multi-parameter attribute analysis techniques, it is not only expected to describe the geometry and tectonic features of the reservoir, but also to describe the reservoir’s internal characteristics (such as physical distribution, gyration, fluid-containing properties, etc.). Based on the analysis of the calculation principle of several important parameters, the model parameters forward modeling is studied. Based on this, parameters extraction and research of high resolution 3D seismic data in a salt lake basin are carried out. The results show that for the seismic data with high resolution and high signal-to-noise ratio, it is credible to study the lateral variation of reservoir using attribute analysis
