Background
Evaporite deposits have been found in many basins of different nature worldwide, with the formation deformation and evolution of about 120 basins being significantly affected by salt formation movement.

A specific example is given below to illustrate the specific application of the salt structure pattern analysis method proposed by the present invention.
The basin of the coastal sea is positioned in the north of the coastal sea, extends in the east-west direction, has the length of 1000km and the widest position of 650km, has an outline similar to an ellipse, and has the basin area of 50 multiplied by 104km2. The riparian basin belongs to the southeast corner of the eastern European terrace in the tectonic zone of the large area, the north and the west of the basin are adjacent to some of the raised constructional units in the south of the eastern European terrace, and the east and the south are adjacent to the sea-west fold belt(including southern Ural, southern Enba, Karakul, etc.) are adjacent.
The lower phylogenetic part of the coastal basin develops salt dunes which are thicker than kilometers, the salt dunes are as thick as 2600m in the west of a work area, and are generally 400-500 m in the east of the work area. The well drilling data show that the zone velocity of the salt layer in the zone is 4500m/s, the average velocity of the surrounding rock of the upper two-layer stacking system is about 3800m/s, but the velocity of the surrounding rock is greatly changed. For marine sedimentary formations, the velocity of the salt deposit is more stable laterally. However, due to the influence of the overlying salt dome, the velocity field of the stratum under the salt dome is abnormal, the position right below the top of the salt dome has the lowest velocity, and the stacking velocity and the RMS velocity corresponding to the high-speed abnormal body are both shown as the phenomena that the velocities of two wings of the salt dome are higher and the middle velocity is lower. The effects of the salt dome boundary on the underburden remain. In the process of manufacturing the depth domain data volume, a certain degree of special treatment is needed at the salt dome to eliminate the abnormal phenomena, so that the 'pull-up' phenomenon can be eliminated to a too large degree, and the local structures under the salt which may actually exist are covered. Therefore, analysis and research on salt formation patterns and formation causes are needed to guide seismic data interpretation and under-salt exploration deployment.

And finally searching a salt structure pattern library, and determining that the salt structure pattern in the region is a salt structure pattern corresponding to D-H & lt 3H, wherein the salt dome is characterized by being a soil dome, and the salt structure is upwards narrowed.
