Establishment of Geological Model of Ancient Pockmarks in Fuman Oilfield, Tarim Basin

doi:10.7657/XJPG20240408

Abstract

Abstract:

For the pockmarks between major faults and in deep marginal-platform beaches in the Fuman oilfield, a seismic geological model 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 altering 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 foundation for the effective prediction of Ordovician ancient pockmark reservoirs in the Fuman oilfield, Tarim basin.

Key words: Fuman oilfield, forward modeling, ancient pockmark, carbonate rock, strike-slip fault, genetic model
