For the conditions of the development of bottom water-drive reservoirs in terrigenous deposits with low permeability of oil-saturated rocks in the dome of the formation, we propose a technology of reverse oil cone creating for effective residual oil reserves development. To visualize the oil recovery process, we created a hydrodynamic model, which makes it possible to increase the efficiency of the proposed technology, as well as to regulate the technology parameters. We considered the issues of the following models creating: the water cone formation during the near-roof part of the formation perforation; the a cone of oil formation in the process of water withdrawing from reservoirs with cutoff water saturation; erosion of the oil cone during its production from the interlayers with the highest oil saturation. The parameters influencing the efficiency of proposed reverse cone technology application are determined.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
