Abstract:
The feasibility of development seismic inversion and detailed reservoir description are difficult ,in order to solve the problems curve reconstruction was proposed based on frequency division compensating. According to different-frequency logging curves reflecting different geological and sedimentary features, using the theory of high frequency recovery and low frequency compensation rebuild quasi-wave impedance logging curves. Inversion analysis test shows that through key technologies such as re-sampling data, introducing simulated annealing algorithm and highly controlling extent of participating well-pattern. Meanwhile, forward modeling and inversion practice prove that 2 meters sandstone could be recognized by development seismic. But it was unstable about the thin sandstone under 2 meters, unless the sandstone coated by mud surrounding rocks above 2 meters. Well-to-seismic integration correct the change of sedimentary for the vary of channel structural body, continuity, scale, combination and multi-period channel. Multi-period channel was divided through utilizing morphological variation and height deviation of logging curves, researching channel vertical evolution assisted retrieval sections , determining single-period river boundary finally.
