Abstract：The paper adopts three steps inversion theory combining non well constrained inversion of seismic low frequency, well constrained, wave impedance model inversion of medium frequency with non linear logging inversion of high frequency, constructs a subtle geological model in combination with drilling, logging and production data of oil field, conducts integrated lateral predicting for thin sand shale interbedding, the resolution of predicting thickness of thin bed is 2～5m. Spreading application of the method for reservoir predicting in three northern blocks of Songliao basin showed a good results. The technique has become a more effective and more perfect applied method for real production; it has a guided role in oil field development.
