## 3 Actual Seismic Data Application
### Application Example in YGU Block
According to the Tarim Oilfield, the drilling success rate has increased from 75% in 2017 to more than 95% in 2021, and the proportion of high-efficiency wells has increased from 20% in 2017 to 75% in 2021 (Figure 15). Through the application of this method and process, many wells have achieved high production (Table 1), and the current production state is stable. It supports the exploration of block reserves and promotes the deployment of 1130 km\({}^{2}\) high-density 3D seismic to the south of the HD-YK block (540 km\({}^{2}\) will be constructed first in the winter of 2021), with obvious effects. Figure 14: RMS amplitude attribute plan of target layer of the YGU block. (**a**) the attribute plan based on original seismic data; (**b**) the attribute plan based on heterogeneous SWFA data obtained by this method. Figure 13: An arbitrary profile in the YGU block. (**a**) original seismic data; (**b**) heterogeneous body SWFA data. According to the application effect of the three blocks, this method can be applied to areas with slow changes of structural characteristics or areas with a severe change of structural characteristics, which is obviously helpful to the identification of heterogeneous reservoirs. Through the method of dip scanning structure guided transverse filtering, the fault distribution characteristics in the study area can be effectively understood in the absence of structural horizon interpretation, and the initiative in time can be won for block geological understanding and well location deployment. \begin{table}

Figure 15: The drilling success rate and high-efficiency well ratio of FMOF in recent years (according to Tarim Oilfield Company). The method can be applied to depth domain and time domain stack data. It can also be used for reference by identifying geological abnormal bodies in gravity, electrical and magnetic exploration, and can also be applied to engineering geological disaster investigation.
