Establishment of Geological Model of Ancient Pockmarks in Fuman Oilfield,Tarim Basin
For the pockmarks between major faults and in deep marginal-platform beaches in the Fuman oilfield,a seismic geological mod-el was established based on the detailed interpretation of 3D seismic data and the analysis of the drilling and seismic data in the oilfield.This model enabled a simulated analysis of the variations in seismic response characteristics of the ancient pockmarks in the oilfield by al-tering the factors such as pockmark scale and fracture density.Consequently,seismic-based pockmark identification models were proposed,along with an understanding of the distribution,genesis and hydrocarbon potential of the pockmarks.The study results provides a founda-tion for the effective prediction of Ordovician ancient pockmark reservoirs in the Fuman oilfield,Tarim basin.
