These reservoirs are laminated and vertical superimposed with rapid lateral variation. The reservoirs have no obvious architecture on seismic sections. Generally developed beneath lithologic interfaces, reservoir reflections are submerged by the strong reflection of the lithologic impedence interface, making it very difficult to predict reservoir distribution. In order to enhance the precision of laminated pore-dominated limestone reservoir prediction, seismic forward modeling and wavelet decomposition technique are combined to qualitatively predict reservoir development zone; and both facies-controlled stochastic inversion and depth-domain inversion method are applied to quantitatively predict the reservoir distribution. The integrated seismic approach is proved effective in Block M at the eastern margin of the Pre-Caspian Basin, with prediction results matching well with drilling results.
