Abstract:According to the heterogeneous heavy oil reservoir definition, this paper discusses the reservoir character and classification,and summarizes the unique logging response characters of this reservoir such as upside down oil water location, abnormal oil and water relation. We think that the lithologic trap and abnormal oil-water gravity segregation phenomenon can explain the unique log response characters according to hydrocarbon migration and accumulation theory, then, we put forward new fluid typing method and new inlayer reservoir further classification evaluation method (NIRFCEM), and applied in field examples. This NIRFCEM is newly developed for inlayer lithofacies subdivision, and oil enrichment for logging evaluation. The newly founded NIRFCEM overlay methods for porosity and oil saturation, and effective permeability and movable fluid saturation achieve good geological consistency in practice, which supplies highly accurate logging evaluation results for the development and perforation optimization.
