There are many oil and gas discoveries along NE-trending strike-slip faults in Shunnan area

Tarim Basin

indicating that the strike-slip faults can be a controlling factor for hydrocarbon migration and accumulation. Considering deep burial depth

low signal-to-noise ratio and small fault displacement along the faults strike

seismic responses of small fault and fracture zones are not clear and difficult to be interpreted. Based on the actual three-dimensional seismic data of the Shunnan area

we carried out the numerical simulation for two models

model of limestone top surface and model of limestone internal surfaces. We also clarified seismic response characteristics for faults of different scales and established seismic identification model. According to the geological features and seismic recognition pattern of strike-slip faults

we selected sensitive seismic attributes such as trend surface

fine coherent

ant body and likelihood. Finally

based on the results of fracture prediction

the paper gave a description and evaluation on the strike-slip fault zone

such as fracture properties

levels

segmentation

and cavity features

and gave advice to the optimization of exploration plays and prosepects.
