New theory and method of fluvial reservoir architecture study:Concepts, contents and characterization of offshore oilfield fluvial compound sand-body architecture
摘要
Abstract
The architecture theory and characterization method of fluvial reservoir, which were based on dense wells data of onshore oilfields, have become relatively mature after decades of research. Nevertheless, it is challenging to apply this theory and method to offshore oilfields, where only sparse wells drilled. Through years of exploration, our research team proposes a new architecture theory and character-ization method for fluvial reservoir of offshore oilfield by combining well data with seismic data and taking compound sand-body as major research target. Compared with previous study, this new approach employs technologies such as 3 D prototype model reconstruction, seismic architecture facies prediction and seismic driving deterministic geological reservoir modeling to detailedly study the 5 th, 6 thand 7 tharchitecture units of fluvial reservoir (compound channel belt, single channel belt and compound point bar) , which shows obvious advantages on substrata division and correlation and discontinuous permeation barriers prediction in development phase. At present, there are still challenges applying this theory and method to fine geological modeling and numerical simulation. It's important to make full use of seismic data and develop artificial intelligence ways to improve seismic interpretation.关键词
