Factor Dykstra-Parsons was calculated in order to determine the possibility that the effective application of polymer flooding at the field. Since heterogeneity reservoir petrophysical parameters affect the rate of production from a formation. Therefore, the numerical determination of this parameter can be used as one of the criteria for evaluating the possibility of using polymer flooding. The paper was reviewed, a review of thetheory on the principle of determining the heterogeneity Dykstra-Parsons. Matching coefficient similar field where the applied polymer flooding has also been considered. It was also considered further research using the coefficient.Қаралған мақалада Нұралы мұнай кенорындағы біртекті еместілікті Дайкстра Парсонс коэффициентпен анықтау. Дайкстра-Парсонс коэффициенті полимерлік суландыру эффективті қолдану үшін есептелген. Мұнай беріштігіне өткізгіштігіне əсер етіледі. Осыған орай сандық түрінде бұл параметр полимер суландыруына мүмкіндігінің критерийі болып есептеледі. Мақалада Дайкстра-Парсонс теориясы жəне басқа аналогиялық кенорындар коэффициентін пайдалана отырып, келешектегі жұмыс нəтижесі де қарастырылған.Статья посвящена определению коэффициента неоднородности Дайкстра Парсонса нанефтегазовом месторождении Нуралы. Коэффициент Дайкстра-Парсонса рассчитывался для того,чтобы определить возможность эффективного применения полимерного заводнения наместорождении. Так как неоднородность петрофизических параметров пласта влияет накоэффициент добычи с пласта. Следовательно, числовое определение этого параметра можетбыть использовано как один из критериев по оценке возможности использования полимерногозаводнения. В статье был проведен обзор теории определения неоднородности по принципуДайкстра-Парсонса. Также было рассмотрено соответствие коэффициента аналогичныхместорождений, где применялось полимерное заводнение. Также была рассмотрена дальнейшаяработа с использованием коэффициента.Keywords: Dykstra-Parsons coefficient, Reservoir heterogeneity, Polymer Flooding, Permeability Flow,EORIntroductionReservoir heterogeneity is crucial for theEOR methods as the polymer flooding. Nuraly oilfield is located in South Turgay Basin in Kazakhstan. Reservoir is comprised sandstones and the siltstones. Reservoir is the complex structure consisted by the sand lenses. That indicates the depositional environment is the fluvial. There are four main productive horizons. Permeability of themain oil horizons varies from 0,031 to 2,2 μм2. Pilot polymer flooding started in 2014 in this oilfield. Production increase in the oilfield still has been calculating. If it will be reasonable it will be completed the bigger field pattern implementation. Thus the heterogeneity of the oilfield is very important to predict the EOR performance of the field. Dykstra-Parsons coefficient of permeability variation is a common descriptor of reservoir heterogeneity. It measuresreservoir uniformity by the dispersion orscatter of permeability values. A homogeneous reservoir has a permeability variation that approaches zero, while an extremely heterogeneous reservoir would have a permeability variation approaching one.ConclusionFollowing our study of reservoir heterogeneity of the Nuraly oilfield we can conclude1. Reservoir heterogeneity is suitable forsuccessful polymer flooding implementationin Nuraly oilfield.2. Further studies of field different fieldpatterns and reservoir modeling implementingthe Dyksta-Parsons coefficient is necessary tobe conduct.REFERENCE1. L.Jensen, I.D.Currie.
