Flake-Like Reflection' Carbonate Reservoir Appraisal: A Case Study in Tarim Basin

‘Flake-like reflection’ carbonate reservoirs in the Tarim Basin, a kind of secondary carbonate reservoirs formed by honeycomb vugs with complex pore shapes, have not been routinely explored like ‘Bead-like reflection’ reservoir due to its insufficient reflection understanding caused by rock-physics inaccuracy. Therefore, to build the relationship between seismic responses and reservoir properties as precise as possible, DEM-Gassmann model, which not only considers the influence of pore shapes on velocity but also meets the requirement of ‘dilute’ pores by incrementally adding pores, is employed in the first time to systematically model the pre- and post-stack reflections of ‘Flake-like reflection’ carbonate reservoir with different porosities and fluids in the Tarim Basin in this paper. The relationship between ‘Flake-like reflection’ reservoir properties and seismic responses is eagerly required for reservoir appraisal and well deployment, which will definitely improve reservoir appraisal and exploration efficiency in the Tarim Basin.
