Analysis of the effectiveness of cyclic fluid injection application in various geological and technological conditions of oil fields development

Authors: G.N. Chumako, V.I. Zotikov , I.Yu. Kolychev (Perm National Research Polytechnic University, RF, Perm) , S.V. Galkin (PrognozRNM MIP OOO, RF, Perm)

Key words: cyclic injection, sweep efficiency, displacement characteristics, technological effect, the linear discriminant function, the statistical model .

The analysis of the development of operational facilities with cyclic fluid injection into the formation is analyzed for Perm Krai oil fields. The calculation of the technological efficiency of cyclic injection use according to M.I. Maximov's techniques for water displacement characteristics constructing and specific oil yield dependence on the cumulative oil production by V.D. Lysenko is carried out. The statistical analysis results revealed geological and technological indicators, which have the greatest influence on the efficiency of the implementation of cyclic fluid injection into the formation. The linear discriminant analysis is applied in order to determine the combined effect of informative indicators on the cyclic injection efficiency. Predictive models of the probabilities to gain the technological effect from the introduction of cyclic injection are obtained.
