Forward study on seismic characteristics of Tarim Basin Ordovician carbonate fractured-vuggy reservoir-scale reservoirs
fault-controlled reservoirs are developed in Ordovician carbonate rocks in a key area of Tarim Basin basin.Reservoir identification and evaluation are based on reservoir reflection characteristics and reservoir structure.According to the geological characteristics and exploration difficulties of fracture-vuggy reservoir in this area,a reasonable geological model is established by forward modeling based on drilling and logging data,it is an effective method to assign the corresponding physical parameters to recognize the seismic response characteristics of reservoir.Based on the actual geological characteristics of the fault controlled reservoir in the area,this study designed a reasonable fault-controlled reservoir model to carry out seismic forward modeling,the relationships between different models and seismic response characteristics,reservoir heterogeneity and seismic response characteristics are systematically analyzed,which lays a foundation for further clarifying seismic characteristics and identifying patterns of high-yield wells.
