RESERVOIR MODELING OF A BV₈ FORMATION, SEVERO-POKURSKY FIELD

摘要

One of the main directions of improving the quality of design, management and monitoring of the development of oil and gas field is the use of filtration models.Digital hydrodynamic models of reservoirs and fields make it possible to monitor the dynamics of the production of residual hydrocarbon reserves, more precisely predict the oil and gas production, to model the geological and technical measures to improve oil recovery and performance of the enterprise, more reasonably expect the most rational and cost-effective options for the development of productive reservoirs.In the present paper we describe the construction of digital geological and dynamic models of the object BV₈^1-3, Severo-Pokursky field.As a source of information for constructing a three-dimensional geological model were used parameters of the counting inventory. There also was made a unified digital database of geological and geophysical data on the previously drilled and new wells, which include: data directional survey of wells, the curves of geophysical research, the results of the interpretation of geophysical research, data perforation and testing, the correlation of wells, the mark of water-oil contact in wells.Created on basis of geological model, the hydrodynamic model takes into account basic geophysical and technological factors, and with the required accuracy describes the real hydrodynamic processes occurring in the formations of the field. Comparison of calculated and historical development indicators, such as oil production and water cut, suggests high-quality adaptation of a model and them according to the actual data.The digital filtration model of a BV₈^1-3 formation can be used as a tool for the prediction and analysis of the existing system of reservoir development.
