Low permeability of the thin sandstone reservoirs is an important area of the oil and gasexploration. It is widely distributed at home and abroad. Fuyang reservoir, north of SongliaoBasin is a typical low-permeability thin alternating layers of sandstone and mudstonelithology reservoir, the main areas of the Daqing oil field exploration. According to theevaluation results of the three resources, the northern Fuyang reservoir vision resourcesamount to27.5×108t. So it has a great resource potential and has a good exploration prospects.However, because of complicated geological conditions, the exploration is very difficult, thespend has been low.In terms of reservoir prediction, from the prediction of sand body recognition–reservoirprediction-oily testing This article explores prestack reservoir prediction in thin alternatinglayers of low permeability. The application of seismic sedimentology interpretation to identifysand bodies, the channel sand body is clear portrayed. By AVO shear wave reflectivityqualitatively characterized reservoir,based on the probabilistic estimation of porositydescripted to prediction techniques for quantitation. Applicate elastic parameter inversiontechnology to predict the oil content. The perstack reservoir prediction technique achieveobvious geologic effect in Taipingtun area, that clearly depicts the channel sand body andforms effective reservoir seismic inversion technique of Fuyu reservoir. We require thechannel sand body reservoir prediction chart of F11, F12, F13, F21and F22oil reservoirgroup according to interpreting153.8km2seismic date.The effective reservoir predictionaccordance rate of more than3meters exceeds70percent.At the same time, on the basis ofenhancing Fuyu reservoir imaging research, this article uttermost avoids T2reflective layershielding effect and improves Fuyu reservoir sedimentary rule understanding.The basicideological of high-resolution sequence stratigraphy is fully introduced Fuyu reservoirreservoir prediction, that is be beneficial to Guide seismic exploration.In this paper, the exploration of prestack reservoir prediction is to see initial results. Iteffectively support the exploration deployment of the Daqing exploration area of Fuyangreservoir, Further deepening reservoir deposition and accumulation of understanding of thelaw of the Songliao Basin Young,It speed up the process of Fuyang reservoir exploration.
