基于地震响应模式的薄层河道砂体地震储层预测技术
Technique of seismic reservoir prediction in thin channel sand body based on seismic response model
摘要
Abstract
The fluvial-facies reservoirs of Guantao Formation in Chengdao Oilfield are characterized by thin sand body thickness,multi-stage vertical superposition and discontinuity in plane,which lead to complex injection-production relationship and large productivity difference,and the benefit development faces great challenges.According to the geological characteristics of channel sandbody,by utilizing sparse pulse inversion and high-resolution geological statistical methods,combined with seismic sedimentology slicing,this article accurately decribes the reservoir distribution range of channel sand body,and successfully solves the difficulties of reservoir description during the development of Chengbei area.Firstly,the seismic reflection characteristic template of river channel sand body is established through seismic response model analysis.Then,through seismic sedimentological slices,the spatial and temporal changes of the reservoirs inside the small beds are described.Finally,through inversion and attribute fusion,the reservoir distribution of channel sand body is realized,and the reservoir thickness is quantitatively described.The precise description of the reservoir from qualitative to quantitative was achieved,and the predicted results matched the sand thickness of the well point by 89％.The existing reservoir prediction techniques are effectively improved,and a complete technical sequence suitable for fluvial reservoir description is established,which lays a good foundation for the fine description of the same type of reservoir in the future.关键词
