Abstract: Reservoir description is one of the significant techniques to understand fully the reservoir geology of complex oilfields. The authors have worked for years on this subject, and developed a new integrated method of reservoir description which consists of comprehensive utilization of information of geology. seismics logging and well testing, micro-computer programs, seismic reservoir estimation, multiple-well logging evaluation, qualitative and quantitative survey on the reservoirs. This method has been successfully applied to describing lithological and highly faulted reservoirs and has become a useful tool to reveal the geological mystery in the oilfields. This paper discusses and ruggests five types of geological models for different reservoirs, including oilfield scale model, sedimentary cycle model, single sand-body model, micropore structure model and logging model for the oil-producing intervals. This technique has helped to find more reserves in complicated oil-fields.
