摘要

The purpose of this work is to identify the reservoir parameters at which efficiency of the line development system using horizontal wells with multi-stage hydraulic fracturing with waterflooding is lower that efficiency of the depletion drive development. The key factor reducing efficiency of developing such objects using the waterflooding methods is low reservoir pressure conductivity and, therefore, relatively long time of well productivity response to injection. The authors use NPV as a criterion of development efficiency. A certain example (low-permeability reservoirs of the Priobskoye field for which oil production is calculated using the methods of numerical hydrodynamic modelling) is considered. An analytical technical and economic model of low-permeability reservoir development in the depletion and using waterflooding with dimensionless parameters has been also built. For each type of impact on a reservoir, the optimum parameters of the development system shall be determined to further compare efficiency of the depletion and development with waterflooding. The results of calculations based on the numerical model have been summarized in the form of a dimensional chart to determine efficiency of waterflooding low-permeability reservoirs of the Priobskoye field. The results of application of the analytical model are provided in the form of a dimensionless chart.
