The relevance of the research is determined by the fact that the availability of a geological and simulation model of a field adapted to historical data is a powerful tool, which helps engineers control development and consider the effectiveness of the proposed solutions in the near future. Therefore, to obtain reliable results, the quality of constructing reservoir model, taking into account their geological features, is very important. The permeability anisotropy can be considered as one of these models. It is especially important when considering reservoirs with low poroperm properties, the development of which is currently actively started. The object of the study is one of oil fields of the Tomsk region, consisting of terrigenous sediments. A feature of the field is its location in the system of complex local lifted blocks of various orders. The main productive reservoir is represented by Jurassic sediments, which formed in a regressive-transgressive sedimentation series and having a complex distribution of poroperm properties. The research methods are based on constructing a field model and conducting simulation calculations, including the selection of permeability anisotropy close to reality, adaptation of an existing development system, as well as construction and analysis of development maps. The aim of the research includes the assessment of the effect of permeability anisotropy on behavior of reservoir simulation model of oil fields. The aim of the research. It was found that the omission of permeability anisotropy leads to overestimation of cumulative fluid production of field development. Moreover, an increase of anisotropy magnitude does not always lead to increase in cumulative oil production, which undoubtedly emphasizes the peculiarity of geological structure of reservoir. In conclusion, a simulation calculation of the development was carried out in a period 15 years, the results of which also led to conclusions about correctness of use of operations to increase oil recovery.
