Methodical bases of planning and organizing intensive floodingsystems (on example Vateganskoe and Tevlinsko-Russkinskoe fields)

For the oil companies, which are widely used method for the extraction of water flooding of hydrocarbon reserves, always important to address the following challenges: improving the efficiency of water injection; reducing the volume of produced water; reduction of operating costs and the cost of oil production; increasing the volume of oil production. The urgency of the problems increases when it comes to optimizing the development of oil deposits with poorly controlled areal systems or focal flooding. It is for these deposits are characterized by low oil recovery rates and high water cut. In these conditions it is difficult to predict the results of the optimization of water injection by acting on a single hole, which is influenced by others, and, moreover, impossible to solve the main task of production - minimize operating costs and increase oil. Decision of the issue is to improve the process of flooding on the basis of mode control wells. In this case, the term "control regimes" should be treated differently than just a change injectivity. This first pair of geological and technological measures on the production and injection wells, respectively algorithm optimization problem.
Materials and methods
Geological fields data, proxy model, artificial neural network, geological and statistical models, geological and hydrodynamic modeling.
Results
In this work were considered issues of flooding and increase the efficiency of reduction of volumes of produced water by controlling the modes of operation of wells through certain paths algorithms for solving of this problem.
Сonclusions
Establishing mutual well pairs by calculating the Spearman coefficient allows to identify areas not covered by flooding and areas that require waterproofing selective conduct for the purpose of redistribution of filtration flows. The proposed method can be used in the planning of well interventions and optimize flooding system. Principles of perfection flooding system are associated with the lateral anisotropy factor, as well as take into account the structural and gravity factor. The proposed program of work is based on the optimization of operating modes of injection and production wells and is aimed at reducing water production wells and the stabilization of oil production. Formation of the row system development in the central part YuV1 formation necessitates the development of methodical bases and approaches to planning work without preliminary gas separation.
