ABSTRACT: In order to solve the problem of thin reservoir prediction in the context of horizontal well development, a prestack seismic-geological modeling technology suitable for the characteristics of shale oil in Liaohe Depression was studied and summarized. This technology makes full use of the “two widespread and one high” seismic data, seismic interpretation results, velocity data and pre-stack inversion results to establish high-precision models, so that the seismic information plays a leading role in the modeling process and improves the model’s lateral accuracy. The research results show that seismic-geological interaction modeling under prestack seismic prediction constraints can greatly improve the vertical and horizontal resolution of the model, provide a basis for the optimization of horizontal well trajectory and dynamic adjustment, improve the drilling rate of horizontal wells, and meet the exploration deployment and horizontal well drilling needs of the Shale oil reservoir in the middle of the Damintun sag of Liaohe.
