Об одном методе классификации нефтяного месторождения с использованием комплекса геолого-промысловых данных и машинного обучения

Abstract

In machine learning, k-means unsupervised model is used for classification analysis. In this paper k-means model is applied for productivity prediction of giant Western Siberian oilfield. An essential condition for method’s application is availability of digital databases with representative results. Complex method allows combine different reservoir and production parameters: rates, porosity, saturation, frac parameters etc. The method can be particularly useful in complicated reservoirs, e.g. in dual porosity ones, where the relationship between formation parameters (permeability, porosity, saturation) and production rates is unclear and cannot be set by traditional development analysis, particularly in frac environment.
